feat: emit github.pr.opened / github.pr.merged on the event bus#24
Merged
Conversation
Broadcast PR lifecycle events (ADR 0039) so consumers can surface them without
polling — e.g. protoAgent's Fleet Room activity feed rendering "opened PR #123 ·
<title>" for a member agent.
- get_write_tools() takes an optional `emit` (the host's namespaced registry.emit).
github_create_pr emits `pr.opened` {repo, number, title, url, head, base};
github_merge_pr emits `pr.merged` {repo, number, method}. The registry namespaces
them to `github.*`.
- register() passes `emit=getattr(registry, "emit", None)` — hasattr-guarded like the
plugin's other host couplings, so an older host without the seam still loads the
tools, just without events.
- _emit swallows everything: telemetry can never fail a write tool.
Tests: 91 passed.

The conflict resolution (keeping main's `+ get_review_tools(...)` alongside the new `emit=` arg) was hand-wrapped; ruff format wants it on one line. `ruff format --check` is a CI gate, so this unblocks the run. No behavior change.

Broadcast PR lifecycle events on the host bus (ADR 0039) so consumers can surface them without polling.
Why: protoAgent's Fleet Room activity feed can now render "opened PR #123 · <title>" for a member agent, instead of that row being impossible to source.
