feat: v0.8.0 — Claude Code subagent capture, own Joplin notebook, git-root repo tags, multi-root scanning

- Subagents: fold Task-tool transcripts (subagents/*.jsonl) inline as
  collapsible <details> blocks at the spawn point; their own tool traffic
  collapses under the same policy; nesting handled via toolUseId matching
- Joplin: Claude Code gets its own top-level AI-ClaudeCode notebook;
  update_note sets parent_id so notes self-heal/relocate on re-sync
- Repo [tags] in titles via git-root detection (nearest .git ancestor),
  home-wide and cross-workspace; CLAUDE_CODE_REPO_TAG_IGNORE escape hatch
- Multi-root scanning: CLAUDE_CODE_DIR as os.pathsep list + CLAUDE_CONFIG_DIR;
  merged by launch-folder, newer-mtime wins on UUID collision
- 298 tests passing
