Alem Tuzlak 6d49ecbb7b fix(showcase, runtime): subagents fixtures, voice mic format, fine-grained shared-state gating
Three follow-ups on top of PR #4837 that I had on the same branch but
didn't make it into the squash merge.

1. **packages/runtime: stamp `audio/webm` on empty-type Blobs in the
   transcription handler.** Browser MediaRecorder writes the audio as
   webm/opus, but the Blob's `type` field is often empty by the time it
   hits the server. `isValidAudioType` lets empty / octet-stream through
   for compatibility, but OpenAI Whisper then rejects the upload with
   `502 Invalid file format. Supported formats: ['flac', 'm4a', 'mp3',
   'mp4', 'mpeg', 'mpga', 'oga', 'ogg', 'wav', 'webm']` because it
   can't pick a decoder. Reconstructing the File with an explicit
   `audio/webm` type (and a `.webm` filename fallback) makes Whisper
   accept the bytes that were already valid. Monorepo-wide — applies to
   every integration using `/api/copilotkit-voice/transcribe`.

2. **showcase/aimock/feature-parity.json: port 12 subagents fixtures
   from d5-all.json** so the three pills (cold-exposure blog, LLM
   tool-calling explanation, reusable-rockets summary) work in
   production. d5-all.json already has the full research → writing →
   critique chain with substantive content; feature-parity only had the
   single LP remote-work pill. Production aimock loads both files but
   any case where feature-parity wins first-match needs the same
   content. Verbatim port — no fabricated text. Net result: no more
   `[sub-agent error] the writing agent...` on the demo's pills.

3. **showcase/aimock both files: scope shared-state-read-write Greet +
   Plan-a-weekend fixtures with a true all-defaults systemMessage
   gate.** The PR #4837 gate (`systemMessage: "tone: casual"`) only
   caught tone changes — name / language / interests changes still hit
   the canned fixture. Replaced with a two-element array gate (aimock
   supports all-present substring matching, verified in
   `/app/dist/router.js`):
     - `preferences:\n- Preferred tone: casual\n` — breaks if name is
       set (Name line inserts between signature and tone) or tone changes.
     - `- Preferred language: English\nTailor every response` — breaks
       if language changes or interests are added (Interests line
       inserts between language and Tailor).
   With `--provider-gemini` already wired in both local docker-compose
   and Railway prod, any state change now proxies to real Gemini and
   returns a personalised reply.

4. **showcase/aimock/feature-parity.json: re-remove bare 'plan' /
   'steps' / 'mars' / 'dashboard' / 'report' substring catch-alls + the
   bare 'alice' / 'Alice' fixtures.** These were removed in commit
   `ddc2e179` on the PR #4837 branch but didn't survive the squash
   merge, so they're back in main and still hijacking hitl-in-app
   downgrade-#12346 ('plan'), shared-state-rw weekend pill ('plan'),
   subagents 'rockets' pills, hitl-in-chat Schedule-1:1 with Alice
   ('alice'). Replace the alice pair with a single scoped
   `Hi, my name is Alice` fixture for the showcase-assistant
   introduction flow.

Local verification:
- `bin/showcase test google-adk --d5` → 38/38 green, 165s.
- Paired curl on shared-state-read-write:
  - Default state → canned fixture ("Hi — I'm your shared-state co-pilot…")
  - `name=alem` → real Gemini ("Hi there! …")
  - `interests=[Cooking, Travel]` weekend pill → real Gemini ("Hey
    there! Since you're into cooking and travel, how about a weekend
    plan that combines both?")

Production deploys this PR will pick up the aimock fixture changes
(prod loads feature-parity.json from GitHub raw at boot — no image
rebuild needed for that file) plus the runtime change once the
packages/runtime build is republished.
