Replace the dual task/monitor model, NO_REPLY string protocol, and Agent
self-delivery with a single Scheduled Run path: claim-time JobRun snapshots,
isolated Root/named Agent execution, exactly-once complete_scheduled_run
termination, and Scheduler-owned policy delivery through a persistent outbox.
- SQLite v11: drop job_kind/model/delete_after_run, add job_runs with
status/outcome joint constraints and delivery lease columns; one-shot
BEGIN IMMEDIATE migration with atomic rollback.
- Non-blocking JoinSet event loop with bounded run/delivery concurrency;
terminal commit before any channel I/O; recover unfinished runs as unknown.
- ExecutionOrigin::Scheduled propagates to descendants, completion sink is
top-level only, background delegation downgrades to foreground.
- Typed delivery receipts, fixed target_session_id, idempotent
scheduled:<job_run_id> history insert.
- New cron_runs read-only tool; cron_add/update drop kind/model; WebUI and
Health consume the same JobRun projection.
- Bump version to 1.22.0.
- Store default SQLite database at <config_dir>/data/picobot.db instead of
the workspace, keeping session data independent of the workspace; the
reload equivalence check and docs follow the new default
- Add per-skill enable/disable persisted in <config_dir>/skills_state.json;
skills default to enabled, disabled skills are excluded from prompts,
listings, and get_skill at load time
- Add mcp.servers[].enabled (default true); disabled servers are skipped
at activation and by health checks
- WebUI Tools page: switches for Skills and MCP servers, plus a concrete
MCP tool list with connection status and errors
- Add PUT /api/skills/{name} API and expose enabled/tool details in the
skills/status APIs
- Bump version to 1.15.0
