feat(plane): unified status-comment format with duration line (ORCH-016)

Все агенты (analyst..deployer) теперь пишут финальный коммент через единый
хелпер usage.build_status_comment(...) — заголовок «{icon} {Role} — {описание}»,
опциональная строка Verdict/Status из YAML-frontmatter, строка
«Длительность: 4m 12s» (явный duration_s от launcher, fallback из agent_runs
для аналитика), HTML-блок Документы, тех-хвост <sub>tokens · cost</sub>.

- Новые публичные функции в src/usage.py: build_status_comment, fmt_duration,
  get_agent_duration. usage_comment(...) → тонкая deprecated-обёртка (legacy
  тесты в tests/test_usage.py продолжают работать). artifact_links(...)
  переписан на HTML <li><a>…</a></li> (breaking change для внутреннего API,
  но единственный внешний клиент — _post_usage_comments — мигрирован).
- Новый модуль src/frontmatter.py: defensive YAML reader, никогда не raise.
- stage_engine._build_analyst_ready_comment(...) теперь тонкая обёртка над
  build_status_comment(agent="analyst", ...); task_id пробрасывается из
  _handle_analysis_approved_flow для DB-фоллбэка длительности (AC-14).
- launcher._post_usage_comments(...) принимает duration_s, резолвит stage из
  tasks для deployer и worktree_root для AC-8 graceful skipping.

Тесты (16 файлов, 56 новых тестовых функций, покрывают TC-01..TC-25):
fmt_duration table, build_status_comment по всем агентам, DB-фоллбэк,
authorship под per-agent ботами, дедуп-инвариант, regression на
status-only verdict аналитика и финальный notify_done, snapshot
QG_CHECKS + STAGE_TRANSITIONS.

Документация: docs/architecture/README.md (раздел Plane Sync),
CHANGELOG.md (Unreleased Added/Changed).

+
+Unit tests for src.usage.build_status_comment(...) — the single hot path for
+every agent's "I just finished a stage" comment in Plane (ADR-001).
+
+Covers:
+  * Header per agent (icon + role + description from AC-1..AC-5).
+  * Verdict / Status line read from frontmatter (reviewer / tester / deployer).
+  * Длительность line shown when duration_s is supplied; suppressed otherwise.
+  * <a href="..."> link items per agent.
+  * URL base picks gitea_public_url, falls back to gitea_url.
+  * Graceful behaviour when files are missing / no frontmatter (AC-8).
+
+No DB / no network — only the worktree filesystem (via tmp_path).
