v0.1.0 — first public release

First public release.

• Full-featured CLI for Super Productivity over WebDAV (sync-data.json):
  tasks (CRUD, subtasks, tags, moving, ordering), day planning
  (today/planner/agenda), scheduling (reminders, deadlines, repeats), time
  tracking (live timer, corrections, worklog), notes, boards, habit counters,
  day metrics, ICAL/CalDAV providers, archive/restore, backups, doctor
  invariant checks.
• Sync-safe write path: operation log (recentOps), vector clock, ETag/
  If-Match conflict detection with retry, automatic rotating backups before
  every PUT.
• MCP stdio server (sp-mcp) exposing every CLI command as an sp_* tool,
  generated from the argparse parser (1:1 coverage, zero extra dependencies),
  with read-only/destructive annotations and --include/--exclude filtering.
• Agent skill (integrations/skill/superproductivity/) and registration
  guides for Claude Code, Cursor/VS Code/Claude Desktop, Codex, Hermes Agent,
  and OpenClaw.
• 1108 tests: unit (no network) + MCP end-to-end against a loopback WebDAV
  emulator.
