atlas 39b95c2ede treefmt: apply prettier
Pure `nix fmt` output from the commit before this one — no hand edits.
203 files: 52 md, 42 tsx, 32 js, 32 css, 21 ts, 13 html, 8 json, 3 mjs.

Reproduce with `nix develop -c nix fmt` on the parent commit; the result
should be byte-identical to this tree.

None of the 13 `.prettierignore` entries appears here — verified by
intersecting the changed-file list against the ignore file, with a
control proving the intersection finds a match when one exists.

# hive-forge-notify
Per-agent Forgejo notification poller: a long-running daemon
(`hive-forge-notify`) that watches the agent's unread notification list
and turns each thread into a todo the harness surfaces in
`get_loose_ends`. This is why an agent wakes up when someone comments
on its issue or requests its review.
## When to use it
Look here when changing what a forge notification _says_ when it
reaches an agent, or when it reaches one at all: the poll cadence, the
self-echo filter, the comment / review / new-item / state-change
wrapper formats, body-excerpt truncation, and the assigned-issue
rollup all live in `notify.rs`. The behaviour contract — activation
gates, filtering rules, the review-request override — is documented in
[`docs/integrations/forge.md`](../docs/integrations/forge.md), "Notification poller".
## Shape
One bin, three modules:
- **`main.rs`** — argument-free entry point. Reads `HIVE_AGENT_SOCKET`,
initialises tracing, hands off to `notify::run`.
- **`notify.rs`** — the poller: forge client setup, the 30s loop, the
formatters, mark-read, and the in-process delivery-dedupe map.
- **`todo_client.rs`** — one-shot JSON-line client for the harness's
in-agent socket. No retry schedule of its own; see the module doc.
## Why it is a separate process
It used to be a `tokio::spawn` inside the `hive-agent` serve loop. It
never needed anything from the serve loop except a socket path, and
running it in-process meant a harness restart also took forge
notifications down, and linked the whole forge/HTTP dependency tree
(`forgejo-api`, `reqwest`, `time`, `url`) into the serve-loop binary.
It is now a sibling daemon alongside `hive-bash-daemon` and
`hive-matrix-daemon`, with the same contract: it talks to the harness
over the in-agent todo socket and nowhere else.
Forge's own read-state is the durable, cross-rebuild record of what has
been delivered — there is no persisted cursor to migrate or corrupt. A
restarted poller re-scans only the genuinely-still-unread set, which is
tiny by construction because delivery marks the thread read.
