Add 7 optional bot-token fields (plane_bot_analyst..stream) read from the ORCH_PLANE_BOT_* env vars, default empty. Required for per-agent comment authorship; empty values fall back to the shared orchestrator token.
The watchdog used to time.sleep(timeout) then immediately SIGKILL, which cut
claude off mid-write and left half-written artifacts. It now sends SIGTERM,
polls os.kill(pid, 0) for up to agent_kill_grace_seconds, and only SIGKILL if
the process is still alive; ProcessLookupError is tolerated at every step.
Timeout is now configurable via config.py: agent_timeout_seconds (default 1800),
agent_kill_grace_seconds (default 20), and agent_timeout_overrides_json for
per-agent overrides (e.g. {"reviewer": 3600}). AGENT_TIMEOUT is kept as a
backward-compatible alias. The recorded exit_code stays -9 so the ORCH-1
monitor retry/fail logic is unchanged (timeout-kills classify as permanent and
requeue within max_attempts, no retry loop).
ORCH-6: src/projects.py introduces ProjectConfig + resolvers
(get_project_by_plane_id/by_repo, known_plane_project_ids) keyed by
Plane project uuid. Source: ORCH_PROJECTS_JSON env (config.projects_json),
with a built-in default registry (enduro-trails + orchestrator) and
robust parsing (malformed JSON/entries fall back to default).
