fix(monitor): route assistant messages to channels for ACP .claude workdirs (#3286)

* fix(monitor): replace dots in project-hash slug so JSONL is found for .claude workdirs (#3286)

Claude Code's project-directory slug replaces every `.` in a path segment
with `-`. Aegis's computeProjectHash preserved the dot, so workdirs like
`<repo>/.claude/worktrees/x` produced a slug that didn't match the actual
`~/.claude/projects/-...-aegis--claude-worktrees-x/` directory.

discoverFromFilesystemFallback then looked in the wrong folder, the
monitor never found the JSONL, and channels.message('message.assistant')
never fired — so assistant replies never reached Telegram / Slack /
webhooks / the legacy transcript endpoint.

Add a `.replace(/\./g, '-')` to segment sanitization and an assertion
covering the .claude case.

Closes #3286

* fix(monitor): forward messages when watcher hasn't started for THIS session (#3286)

The poll-cycle hand-off between checkSession and the JsonlWatcher missed
historical entries discovered via the filesystem-fallback path.

The guard `!this.jsonlWatcher` only checked whether the watcher
*instance* existed (it always does, once initialized). On the discovery
poll — where readMessagesForMonitor's fallback just set jsonlPath and
read every existing JSONL entry — those entries were dropped, then the
watcher attached at end-of-file and saw no further changes for content
that pre-dated its attachment.

Switch to `!this.jsonlWatcher?.isWatching(session.id)` so checkSession
forwards historical entries on the exact poll where the fallback
discovers the JSONL. The watcher takes over for subsequent appends.

Verified end-to-end with the Telegram channel: assistant messages now
fan out to channels for ACP sessions whose workdir was discovered via
the filesystem fallback (combined with the slug-mismatch fix in the
previous commit).

Closes #3286 (combined with previous slug-mismatch fix).

* chore: trigger CI refresh
