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

+## [0.8.0] - 2026-07-06
+
+Focused on the Claude Code provider after the tool's on-disk layout changed and
+Claude Code sessions proved hard to find in Joplin.
+
+### Added
+- **Subagent capture.** Claude Code now stores subagent (Task-tool) transcripts as separate `<session>/subagents/agent-*.jsonl` files (with an `agent-*.meta.json` sidecar). These were previously invisible to the exporter — all delegated work (reviews, research, plans) was lost. Each subagent is now folded into its parent session inline at the `Task`/`Agent` call that spawned it, rendered as a collapsible `<details>` block labeled with its `agentType`/`description`. The subagent's own tool traffic is collapsed under the same `EXPORTER_HIDDEN_CONTENT` policy as the main dialogue; nesting is handled at any depth via `toolUseId` matching.
+- **Repo tags in Claude Code titles.** Sessions launched from a workspace root all land in one folder-named notebook, so titles now carry the repos each session touched, e.g. `Resume StartWRT project work [start-technologies]` — visible in the note list and matched by Joplin search. A file's repo is the git repository it lives in (nearest ancestor with a `.git`), resolved from tool_use paths anywhere in the filesystem — so cross-workspace work is captured and non-repo noise (config dirs, one-off files, reference dirs) is excluded because it isn't a git repo. Frequency-ordered, capped at 3. Escape hatch: `CLAUDE_CODE_REPO_TAG_IGNORE` (comma-separated repo names). Tags reflect the current git layout, so a since-deleted/moved repo drops from the tag on re-export.
+- **Multiple projects roots.** `CLAUDE_CODE_DIR` now accepts an `os.pathsep`-separated list of roots (a single path stays backward compatible), and `CLAUDE_CONFIG_DIR`'s `projects/` tree is scanned automatically when set. Sessions from all roots are merged by launch-folder; a session UUID present in two roots keeps the newer-mtime copy.
+
+### Changed
+- **Claude Code gets its own top-level Joplin notebook, `AI-ClaudeCode`** (was nested under `AI-Claude` alongside Claude web chats, which made dev sessions hard to find). Existing Claude Code notes self-heal into the new notebook on the next `joplin` run — `update_note` now sets `parent_id`, so a changed provider→notebook mapping relocates notes in place instead of duplicating them. After migrating, the emptied `AI-Claude/{Myworkspace,Services,…}` notebooks can be deleted by hand (Joplin does not auto-remove empty folders).
+
+### Notes
+- The sibling `<session>/tool-results/*.txt` sidecars (externalized large tool outputs) are intentionally not captured — tool_result content is collapsed under the default policy anyway.
