chore(agents): migrate persistent state files to timestamped directories

- Move `CONTEXT.md`, `TODO.md`, `DECISIONS.md`, `TEST_LOG.md` to `context/`, `todo/`, `decisions/`, `test_logs/` directories with timestamps.
- Update `AGENTS.md` and `CLAUDE.md` to define the new workflow: agents must read the latest timestamped file and create a new one when updating.
- Update `daily-scheduler.md` and `weekly-scheduler.md` to initialize tasks using the new file structure.
- Update all daily agent prompts to reference the new directory structure.
- This change prevents merge conflicts on persistent state files by treating them as an append-only log of snapshots.

+# Decisions
+
+- Used `npm` as the package manager because `package-lock.json` exists (per prompt detection rule), even though `pnpm-lock.yaml` is also present.
+- Continued with read-only audit/outdated collection after `npm ci` failed, because `npm audit --json` and `npm outdated --json` still produced valid artifacts.
+- Did **not** attempt dependency upgrades in this run due to Node engine incompatibility (`required >=22`, actual `20.19.6`), to avoid non-reproducible lockfile churn and invalid test evidence.
+- Marked this daily run as completed with warnings rather than failed, since required artifacts and triage report were produced successfully.
