E11 — AI Studio: complete

All 11 Linear issues (ALO-642 through ALO-652) are implemented:

Component	File(s)	Status
ai-gateway.ts transport	src/workers/ai-gateway.ts	gateway-binding + run-gateway modes; defaults to run-gateway (proven path). Never uses plain { binding: env.AI } — observability preserved.
create-tools.ts refactor	src/workers/create-tools.ts	draftScript/planScenes via chat({ adapter: gatewayChat() }); synthesizeTts via generateSpeech({ adapter: gatewayTts() }) + base64-decode.
Studio routes	src/workers/studio.ts	/chat (SSE), /image, /video (enqueue), /captions, /metadata, /videos/:id/thumbnail/from-asset
Video b-roll consumer	src/workers/ai-video-consumer.ts	env.AI.run('google/veo-3.1', …, { gateway: { id: 'x' } }) — binding call from Worker queue consumer, never compat-fetch
Data model + migration	0022_studio_assets.sql	edit_projects, generated_assets (+stream_video_id index), ai_costs; videos.ai_generated + source_video_id alters
AI cost ledger	ai-costs.ts + costs.ts	ai_spend in CostSnapshot; ai_spend_threshold alert; STUDIO_GEN_BUCKET rate limit
Frontend	studio/AIStudio.tsx, studio/ImagePanel.tsx, studio/AnimationPanel.tsx, pages/Studio.tsx	useChat + SSE; image gen + thumbnail promotion; render job polling
GatewayMeta observability	ai-gateway.ts GatewayMeta	op/userId/skipCache/cacheTtl threaded into gateway opts for AI Gateway dashboard filtering
Tests	ai-gateway.test.ts, ai-gateway-tts-adapter.test.ts, ai-video-consumer.test.ts, create-tools.test.ts, studio.test.ts, AIStudio.dom.test.tsx	1146 tests pass
CI guard	.github/workflows/ci.yml step "Lint no direct AI providers"	npm run lint:no-providers — 0 findings

Tests

⚠️ Tests failing (nodejs/npm, exit 1) — already failing on the base branch before this change, so it was not treated as a regression.
