merge: dev into r1/claude-reset-fix

Brings in the n2/ntfy-notifications feature (ntfy.sh push notifications
with per-event toggles, subagent-suppression flag, topic-only input,
Settings UI, dispatcher + transport + config modules, 12+ new tests),
the header declutter (theme picker + Debug panel moved into Settings /
sidebar), the shared theme boot-apply module, and an a11y label for the
remove-panel button.

No code changes from this branch were touched by the merge — the
overlap was purely textual.

Conflict resolution:

1. HANDOFF.md (add/add conflict). Both branches independently put a
   single-purpose HANDOFF.md at the repo root for their respective
   in-flight feature, matching the existing convention (c351719 did
   the same for this branch; 29bdd00 did the same for ntfy). After
   this merge both features ship, so neither is in-flight anymore.
   Archive both into notes/:
     - notes/wake-schedule-handoff.md     (this branch — git tracks as a
                                           rename from HANDOFF.md)
     - notes/ntfy-notifications-handoff.md (dev — recovered from
                                           MERGE_HEAD before deletion)
   The root HANDOFF.md is intentionally absent post-merge; the next
   in-flight branch will create its own.

2. packages/api/tests/routes.test.ts (auto-merged). dev appended ntfy
   stubs to the vi.mock('@dispatch/core', ...) factory; this branch
   appended a 'Wake schedule routes' describe block at the bottom.
   The two regions don't overlap and the textual auto-merge is correct
   (verified: 6 describe blocks, both mock-stub regions and the new
   describe present, no conflict markers).

Verification on the merge commit:

  bun run test       → 31 files, 495 / 495 passing
                       (was 431 on the branch + 64 from dev)
  bun run check      → biome clean, 156 files
  bun run --cwd packages/frontend typecheck
                     → svelte-check 0 errors, 0 warnings

dev can now fast-forward to this commit:
  git checkout dev && git merge --ff-only r1/claude-reset-fix
