Merge 'master' into 'dogfood feature branch' (smoke test run) (#82)

* Fix: human surface lifecycle hardening (#81)

* fix: harden agent-idle, redis loop, git errors, escalation audit

- i_am_idle no longer 500s when auto-pausing a task whose commits are
  stored as dicts: tolerate dict-or-object commit refs and run the
  synthetic-checkpoint computation inside the swallowing try block.
- The stream event loop no longer logs an idle redis read-timeout as an
  ERROR every cycle; the blocking-read timeout is treated as a normal idle.
- Git command failures surface git's own (secret-scrubbed) stderr in the
  error message instead of a bare 'Command failed', so push/fetch
  rejections are diagnosable; the injected PAT is redacted.
- The escalate-to-pool redirect emits the task.pending audit event,
  closing a status mutation that previously skipped the audit log.

* fix: let privileged operators set task status via an audited override

The task update route silently dropped a 'status' field in the request body,
so a CEO/admin could not transition a task wedged in a state with no valid
in-band move (e.g. a blocked task whose work merged out-of-band) — the panel
returned 200 while nothing changed. Add 'status' to the update schema and
apply it through a new audited 'admin_set_status' that bypasses the strict
transition validator but always records the audit event. The override
requires elevated permissions; ordinary field updates are unchanged.

* fix: stop human chat sessions from expiring between messages

Messaging sessions fell back to a hardcoded 300s idle timeout, shorter than a
normal pause in a human conversation: the sweeper closed the session and the
next message opened a new one, so a person could not hold a continuous chat.
Make the idle timeout configurable (session_idle_timeout_seconds, default
3600) and resolve an unset timeout to it at every session-creation path
instead of the 300s column fallback.

* fix: resolve doubled doc paths and stop the indexer warning flood

The doc-path resolver returned absolute paths verbatim, so a documenter path
that doubled the base segment (/app/docs/docs/...) never resolved on disk and
the docs never indexed into RAG. Reduce an absolute path under the docs base
to a relative one before normalizing, leaving truly-external absolute paths
for the indexer to skip. The indexer now skips non-markdown source files and
logs a missing/non-doc source at debug instead of warning on every pass.

* fix: reject project repo URLs that point at a protected repository

Add a configurable denylist (protected_git_urls) enforced in the project
create and update paths, so a project cannot be registered against a
repository that must not receive agent commits or merges (e.g. the roboco
source repo during a smoke run). Empty by default (no behavior change);
operators set it to sandbox smoke-test projects.

* fix: let an agent release a blocked task back to the pool

A developer (or QA/doc) trapped on a 'blocked' task had no legal forward
move — every verb rejected from that state — so the dispatcher kept
respawning it with nothing to do. Allow 'unclaim' to release a blocked task
the agent owns back to pending (assignment cleared, work session abandoned,
audited), so the cell PM can re-delegate it instead of the agent churning.

* fix: keep blocked-dev churn out and cell tasks out of board hands

- The dispatcher no longer respawns the owner of a blocked task: from blocked
  the owner has no legal move, so respawning only churns; it is revived on
  unblock or released via unclaim.
- Escalation no longer hands a cell (backend/frontend/ux_ui) coordination task
  to a board/advisory role — such an escalation is diverted to the cell pool,
  matching the existing executable-task guard. main_pm targets are unaffected.

* chore: add an opt-in full clean-slate to the reset script

FULL_RESET=1 wipes everything under the roboco data root except the
persistent service stores (ollama/postgres/redis) and clears the persisted
agent Claude session dirs (ROBOCO_CLAUDE_STATE_DIRS), which otherwise replay
across runs. Default off — the existing DB/Redis wipe + workspace git-reset
is unchanged.

* fix: read the real commit key (hash) and audit the restore-unblock path

- The auto-pause checkpoint and _extract_first_commit_sha read commit dicts by
  key 'sha', but persisted commits are keyed 'hash' (CommitRef.hash) — the prior
  change stopped the crash but silently dropped every ref. Read 'hash' (sha
  fallback) at both sites; the test now uses the production dict shape so the
  regression can't hide.
- unblock_with_restore set status directly and skipped the audit log; emit the
  status-transition audit there too, like the other direct-set paths.
