기존 4-line narrowing 체인 (e.kind !== 'empty_trash' && ... && ...) 이
union 확장 시 길어짐 → hasNoteId(ev) type predicate 로 통합.
- telemetryEvents.ts: NO_NOTE_ID_KINDS Set + hasNoteId(ev): ev is ... export
- TelemetryService.test.ts: 2 narrowing callsite 단축
- 단위 +2 cases (noteId-bearing / noteId-less)

- EmitInput union 13 → 15
- narrowing guards (noteId 없는 kind 분기) 에 tag_vocab_hit/miss 추가

Earlier test used '/proc/0/...' as the unwritable dir. On Windows this
resolved to 'C:\proc\0\...' and mkdir({recursive: true}) silently created
it — the silent code path was never exercised, plus filesystem side-effect
leaked outside the test tmpdir.
Replace with a path that points to an existing file (mkdir on a file path
fails on every platform). Also add a companion test that confirms silent
is opt-in: without {silent: true}, the same fs failure DOES throw.
7 tests pass (was 6).
