Root cause: heartbeat.md instructed Master to append inspection logs to
plan.md on every heartbeat, causing plan.md to grow to 209KB (2922 lines
of repeated 'status stable' logs).

Changes:
1. Truncated master/plan.md from 209KB to 7KB (kept pipeline records,
   removed 2800+ lines of repeated heartbeat logs)
2. Updated heartbeat.md rules:
   - Banned appending inspection logs to plan.md
   - Added token budget awareness (10KB file read limit, prefer grep/find)
   - Normal heartbeats should reply '[心跳正常]' without using tools

Layer 1 (P0): Per-agent session mutex
- heartbeat-service.js: skip heartbeat if previous session still active (30min safety valve)
- agent-chat.js: reject concurrent /chat requests for same agentId with different convId (429)
  Multi-turn conversations on same convId still work normally

Layer 2 (P1): Advisory file lock utility
- server/utils/file-lock.js: O_EXCL-based .lock file mechanism
  Auto-cleanup stale locks, graceful degradation on timeout

Root cause: HeartbeatService creates new convId per heartbeat, spawning
independent Claude CLI processes that concurrently write config.json and
SKILL.md, causing rollbacks and FRAUDULENT scores.

Templates with new train data (hunt/digest/evolve):
- agent-creator, auto-publisher, clickbait-copywriter
- community-manager, competitor-spy, data-harvester
- digester, weibo-scraper, interactive-video-selector
- lemonv_drama, reddit-scraper, story-architect

Updated configs & plans for all active templates.
Updated agent states (master, innovator, hunter, evolver, digester).
Added CLAUDE_EFFORT=low to .env (global disable thinking).
Updated bin/lemon.js CLI tool.

.gitignore: exclude evolve intermediate artifacts (FRAUDULENT, batch/eval
scripts, iteration logs/scores, scorer versions, SKILL versions, .env)

- New template: content-selector with skills, train data (hunt/digest/evolve)
- youtube-crawler: add workspace archive, digest_v2, evolve_v2, mock data
- Update agent todo/plan/SKILL files for digester, evolver, hunter, innovator, master
- Update server/routes/agent-chat.js
- Update .gitignore: exclude runtime data (memory, sqlite, __pycache__, temp files)

- Add YouTube Data API v3 key to .env
- Update start.sh to auto-load .env file on startup
- Add youtube-crawler Skill template with full lifecycle
- Add digester/evolver agents for YouTube crawler
- Update scheduled tasks and master plan logs

…day window, skip old files

…writes (4KB/1s), remove messages.log fallback in loadHistory

…to prevent EADDRINUSE

1. Workspace page: left file tree + right detail/editor panel
   - File info: name, path, size, created/modified timestamps
   - Three view modes: Code / Preview / Edit with save
   - HTML files auto-open in Preview tab (sandboxed iframe)

2. Backend APIs:
   - GET/PUT /:companyId/workspace/files (list + content + save)
   - PUT /:companyId/files/content (company file save)

3. Navbar: removed Skills/Jobs/Pipeline, added Workspace
4. All nav links open in new tabs (target=_blank)

- Fixed .gitignore: data/system/ prefix was missing (old paths never matched)
- Removed tracked memory/, conversations/, uploads/, .tasks/ files
- Only memory.md and hippocampus.md are kept (template skeleton)

- Added inline editing for template description and type fields
- Implemented Delete Template functionality (removes both file system and registry entry)
- Added confirmation safeguards for the destructive delete action
