A rebuild's MetaSync resolves the head of the swarm's internal/meta once and
records it; the prebuild and the swap build that flake instead of the hive's
own, and a first deploy does the same in Create. hive-priv takes the commit as
a validated meta_rev on UpdateContainer and CreateContainer and builds from its
own forge URL (HIVE_PRIV_FORGE_URL).
The head is used only when its flake lists the agent at the config commit the
forge's main is at; otherwise, and when the repo has no commit or this hive has
no core token file for nix's git, the hive renders locally as before.
hive-c0re's and hive-priv's gitconfig now share the forge credential helper and
rewrite the forge's https URLs to http, which hive-priv lacked.
A deploy request whose rev hive-c0re refuses (fetch failed, or the rev
does not descend from applied/main) no longer tries to comment on the PR
that merged it. Off the forge host that attempt always failed with "forge
core token absent". The refusal now logs at ERROR, message unchanged, and
the new `hh-config-rev-refused` Grafana rule fires on it.
Deleted with the posting: actions::post_rev_deploy_failure_to_pr, the
whole forge/pr_comment.rs (config_repo, merged_pr_for_commit,
post_pr_comment), and ReaderToken::value, whose only caller was
merged_pr_for_commit.

swarm-controller now gives every hive in its directory a forge account,
`hive-<hive>`, in a new `hives` team of `agent-configs` (read on
`repo.code` + `repo.pulls`, every repo including later ones), and mints
one `read:repository` token named `swarm-hive` into the store at
`swarm/hives/<hive>/forge/token`. A five-minute pass queues a
`MintHiveForgeToken` node for a hive whose token is missing or no longer
matches the forge, whose account is missing, or whose team membership or
team settings drifted. A hive whose store or forge read failed is never
queued, so an outage cannot rotate every hive's token. The token decision
reuses `agent_token`'s classifier and replace step, now parameterised by
name and scopes.
An agent may be called `hive-<x>`. The hive account is created with
`hive-<hive>@hives.hyperhive.local` and the job refuses an account by that
name with any other email before it locks it down, adds it to the team or
mints for it; agent creation already refuses the hive's account by the
same email check.
The controller's bao policy gains the `swarm/hives/+/forge/token` leaf
(create/read/update), pinned by the bao-grants module-eval assertion. The
hive's own policy already reads `swarm/hives/<hive>/*`.
hive-c0re reads that token through `forge::reader_token()`, falling back
to the core token file when the store holds none, and uses it for:
fetching a merged config rev (swarm deploy, `hivectl forge
reconcile-config`), reseeding a purged `applied`, the meta-update
cascade's fast-forward, seeding `proposed` on first deploy, and finding
the PR that merged a refused rev. Those reads no longer require a local
`hive-forge` container. The `/knowledge` clone moves from the forge
host's boot sweep into the knowledge pull, so every hive clones it.
Posting the deploy-failure comment on that PR stays on the core token.
