swarm-builder: build each agent config PR head and post a commit status

A new `swarm-builder` service, in its own container on the host that sets
`deploy.builder.enable` (defaulted on by `allSwarmServices` where the host
has the builder's store leaf, like the review classifier).

When an `agent-configs/<agent>` PR is opened, reopened or synchronized,
swarm-controller queues a `build_agent` jobq node. The node sets a
`swarm-builder` commit status to pending on the PR head, sends
`{agent, rev, pr}` to the builder over NATS request-reply
(`$SWARM.builder.build`), and writes success (store path), failure (last
line nix printed) or error (no builder / no reply) on the head. The node
fails when the build does, so the Jobs page matches the PR.

The builder builds nix/builder/check-flake's `check` with every input
overridden: hyperhive and nixpkgs to the host's own
`c0re.hyperhiveFlake`/`c0re.nixpkgsFlake` (what a hive there renders into
its meta flake), and the agent to the PR head on the forge. Evaluation is
pure and runs in the container; builds go to the host nix daemon as an
untrusted client. The private config repo is fetched with the token of a
new read-only `builder` forge account (in the `hives` team), which the
controller mints into `swarm/services/builder/forge/token`; git gets it
from a credential helper reading the child's environment, so it is in no
argument or URL.

Credentials: a `builder` store leaf minted by glue-bao-tls on the store
host, a `swarm-builder` reader policy (forge token + its own OIDC client
secret), an authelia machine client, and a `--builder-client` grant in the
queue's auth-callout responder. The controller gains a grant on the token
path and the secret publisher a deny on it.

This is the agent-config build check atlas scoped on #5081 (slice 3):
nothing is pushed to a cache, nothing is written to KV, and a red status
gates no deploy. The check composes agent-base + the config without the
values a hive adds (CA, docs, claude-code path, ports, input follows), so
it can disagree with a hive's own build.

| `swarm/agents/<agent>/matrix/main` | `swarm-controller`, with the swarm's appservice token, at agent creation and in a five-minute pass | the agent container itself, under the certificate its hive passed in | ✅ the pass re-mints when the stored token is missing, unknown to the homeserver, or someone else's | ✅ `hive-matrix-daemon` exits when the homeserver rejects its token, and a five-minute timer restarts it, which reads the store again |
| `swarm/agents/<agent>/matrix/<account>` | `swarm-controller` | the agent container itself, under the certificate its hive passed in | must be stated | must be stated |
| `swarm/agents/<agent>/matrix-recovery/<account>` | `swarm-controller`, a random passphrase for every account listed under the agent's `matrix/`, in a five-minute pass | the agent container itself, under the certificate its hive passed in, when `hive-matrix-daemon` brings the account up | ❌ never replaced: the account's server-side key backup opens only with the passphrase it was enabled with, so the pass writes only to an empty path | ❌ read when the account comes up; an account whose passphrase lands later turns backup on at the next daemon start |
| `swarm/controller/swarm-controller/matrix/appservice-token` | `swarm-matrix-ctl`, inside the `hive-matrix` container, once | `swarm-controller`, under its own certificate | ❌ `swarm-matrix-ctl` mints it once; the container keeps its copy and republishes it when the store's differs | ✅ the controller reads it on every five-minute matrix pass |
| `swarm/controller/swarm-controller/oidc/client` | authelia, at its first boot; `swarm-secret-publish` copies it in | `swarm-controller`, under its own certificate, at start and on refusal | ❌ authelia mints it once. A re-mint is republished by `swarm-secret-publish`'s path unit | ✅ read at start and held in memory; read again when authelia refuses it, at most once per backoff of 5 s doubling to 5 min while the store holds the refused value |
| `swarm/controller/swarm-controller/forge/token` | the forge, inside the `hive-forge` container, once; `swarm-bao-forge-publisher` on the forge's host copies it in under its own certificate, with a write-only grant | `swarm-controller`, under its own certificate, at start | ❌ the forge mints it once and keeps its copy in the container; the publisher writes that copy each time the forge container starts and each time the mint writes the file | ❌ the controller reads it at start, and in the background with backoff until it first finds it; a replaced token reaches it with the next restart |
| `swarm/agents/<agent>/bao-mtls` | the store's agent PKI mount (`deploy.bao.agentPkiMountPath`), which generates the key, at `swarm-controller`'s request at agent creation | `hive-c0re`, under the hive's own certificate, when it writes the agent's container config; then `hive-agent-bao-identity` in the agent container, under the leaf it holds | ✅ `swarm-controller`'s five-minute pass re-issues a live agent's leaf once it's past half its validity (45 of 90 days, read from the certificate itself) | ✅ `hive-agent-bao-identity` re-reads it every 10 minutes and swaps a new leaf into `/run/hive-agent-bao-identity/`, which every store login in the container presents. It reads under the leaf it holds, so it renews only while that leaf is valid |
| `swarm/agents/<agent>/queue` | `swarm-controller`, at agent creation | `hive-agent` in the agent container, under the agent's own certificate, held in memory — the identity it presents to the swarm queue, naming that one agent rather than its hive; `swarm-logs` in the agent container, under the same certificate, on every query, as the bearer it presents at the log store; `swarm-nats-auth` and `swarm-logs-auth`, each under its own certificate, to check a presented secret | ✅ `swarm-controller`'s five-minute pass re-mints a live agent's secret once it's 45 days old by `minted_at` on the stored object; a secret with no `minted_at` gets one stamped, value unchanged. The pass skips agents declared `Destroyed` — declaring an agent destroyed deletes every version of the path instead, the undo of the mint rather than another one | ✅ `hive-agent` reads the path before its first connect and again on every reconnect attempt, so a reconnect after a re-mint presents the new secret. An open connection keeps the secret it connected with; after a revocation the agent keeps retrying under the queue client's backoff. `swarm-logs` reads it on every query and once more after a 401. `swarm-logs-auth` keeps granting a secret it verified for `deploy.victorialogs.authVerdictTtl` (60 s by default) without reading the path, so a replaced or deleted secret still works at the log store for up to that long |
| `swarm/agents/<agent>/forge-token` | `swarm-controller`, at agent creation and in a pass every 5 minutes over every agent with a store identity | the agent container itself, under its own certificate, fetched to `/run/hive-agent-forge-token/token` | ✅ the controller re-mints when the stored token is missing or no longer matches the forge (last eight characters and scopes) | ✅ the agent re-fetches on a 10-minute timer |
| `swarm/agents/<agent>/forge/<label>` | `swarm-controller`, when an operator links an external forge account in the swarm UI | `hive-agent-forge-accounts` in the agent container, under the agent's own certificate, into `<state>/forge-<label>-token` and `forge-<label>.json` | ❌ an operator's token; replaced only by deleting it and linking the label again | ✅ the agent re-fetches on a 2-minute timer |
| `swarm/agents/<agent>/github-token` | `swarm-controller`, when an operator links a GitHub account in the swarm UI | `hive-agent-github-token` in the agent container, under the agent's own certificate, into `<state>/github-token` | ❌ an operator's token; replaced only by deleting it and linking it again | ✅ the agent re-fetches on a 2-minute timer, and `hive-github-notify` re-reads the file on every poll |
| `swarm/hives/<hive>/matrix/sender-token` | `swarm-controller`, with the swarm's appservice token, for every hive in its directory in a five-minute pass | `swarm-controller` under its own certificate, before it decides whether to mint, and hive-c0re's `stored_sender_token()`, under the hive's own certificate | ✅ the controller's pass re-mints when the stored token is missing, unknown to the homeserver, or someone else's | ✅ hive-c0re's matrix sweep reads the store every run and overwrites its token file when the store's token differs |
| `swarm/hives/<hive>/forge/token` | `swarm-controller`, with the forge's admin API, for every hive in its directory in a five-minute pass | `swarm-controller` under its own certificate, before it decides whether to mint, and hive-c0re's `forge::reader_token()`, under the hive's own certificate | ✅ the controller's pass re-mints when the stored token is missing or no longer matches the forge (last eight characters and scopes) | ✅ hive-c0re reads the store on every forge read |

| `swarm/services/review-classifier/forge/token` | `swarm-controller`, with the forge's admin API, for its `review-classifier` account, at start and in a five-minute pass; the secret publisher's policy denies it | `swarm-controller` under its own certificate, before it decides whether to mint, and on every review it posts as the account; the classifier service's policy doesn't read it | ✅ the controller's pass re-mints when the stored token is missing or no longer matches the forge (last eight characters and scopes) | ✅ the controller reads the store on every review it posts |
