Backfill the two genuinely-uncovered infra-free units from the #244 Part B
test backlog (the rest was already covered by #248/#257):
- use-streaming-dictation: the in-order transcription emitter. Drives the
real hook via renderHook with mocked VAD + deferred transcribeAudio so the
test controls response order. Asserts out-of-order HTTP responses still
emit text in segment order; whitespace trimmed and empty results dropped
while the sequence advances; a failed segment shows one notification and is
skipped so later segments still flush; a response resolving after cancel()
is dropped (stale-epoch guard).
- internal-link-paste (handleInternalLink / createMentionAction): validateFn
reject → no resolve/dispatch; resolve → mention node with the resolved page
+ anchor dispatched via replaceWith at pos; "Untitled" fallback; reject →
raw url inserted as text under a link mark; createMentionAction wiring to
getPageById on success + failure.
Test-only; no production code changed.
