Closes #18.

What changed

adds explicit preserve/change/clear patch semantics for todo updates
validates todo domain values before writes
implements calendar-correct recurrence and duration-aware conflict checks in storage
makes todo/tag/occurrence changes transactional
exposes complete and reopen through the public Python and agent tool surfaces
documents supported recurrence and scheduling behavior

Why

The prior storage contract could not intentionally clear optional values, accepted invalid data, approximated month/year recurrence, and detected only identical scheduling timestamps.

Validation

nix develop -c pytest -q t/test_todos.py — 19 passed
full required gate after merging current master — 155 passed and every scripts/test-*.sh passed
nix build — all five derivations built

Current origin/master was merged into this branch with a normal merge commit. No rebase was used.
