feat(tasks): support markdown scheduled-task loops in .agents/loops

Adds markdown-based scheduled-task definitions ("loops") discovered from
.agents/loops/*.md (project scope, ancestor directories up to the
worktree root) and ~/.agents/loops/*.md (user scope), mirroring the
skills discovery pattern.

File format: YAML frontmatter (name, schedule cron, enabled, model as
provider/model, optional agent/timezone) plus the markdown body as the
execution prompt. Discovery and parsing live in
scheduled-tasks/loops.js; project-config gains reconcileLoopTasks which
runs inside the project write lock on every syncProject:
- identity by task name; a loop takes over a matching task, preserving
  its id and runtime state (markdown wins on conflict with JSON)
- tasks whose loopFile is gone are unscheduled; JSON tasks are never
  removed
- new loops are created under deterministic loop:<scope>:<name> ids
- project scope shadows user scope on name collisions
- malformed files are skipped with a warning and never block valid ones

Runtime state stays in the project config/state store; it is never
written to the markdown files. Module documentation updated with the
file format and reconciliation rules.

Fixes #2583

/**
* Reconcile discovered `.agents/loops` definitions with the persisted JSON
* task list.
*
* Rules (documented in scheduled-tasks/DOCUMENTATION.md):
* - Identity is the task NAME. A loop whose name matches an existing task
* takes that task over: its schedule/execution/enabled are overwritten
* from the file while its id and runtime state are preserved (markdown
* wins on conflict).
* - A task whose loopFile no longer matches any discovered loop file is
* unscheduled (removed). JSON-configured tasks (no loopFile) are never
* removed.
* - Loops with no matching task are created under a deterministic
* `loop:<scope>:<name>` id, so runtime state survives restarts.
* - Malformed definitions are skipped with a warning and never block valid
* loops; the scheduler passes only parsed definitions, and normalization
* failures here are isolated per loop.
