refactor: consolidate apps/ai into apps/api

[devin-ai-integration]

Summary

Consolidates the Rust AI service into apps/api and removes the legacy TypeScript API.

Key changes:

• Remove old TS API
  • Deleted apps/api (TypeScript app), doxxer.api.toml, and Taskfile.yaml api include.
• Rename ai → api (Rust)
  • git mv apps/ai → apps/api
  • Renamed apps/api/fly.toml → apps/api/fly.ai.toml to preserve existing hyprnote-ai Fly config
  • Cargo workspace: "apps/ai" → "apps/api"
  • apps/api/Cargo.toml: package name "ai" → "api"
• Config updates
  • bacon.toml: default job/api job updated, -p ai → -p api, watch path apps/ai → apps/api
  • doxxer: renamed doxxer.ai.toml → doxxer.api.toml; tag filter ^ai_v → ^api_v
  • packages/api-client2/openapi-ts.config.ts: input path apps/ai → apps/api
  • apps/api/Dockerfile: all self-references updated to apps/api and -p api; binary renamed to api
  • apps/api/AGENTS.md: env output path updated to apps/api/.env
• GitHub workflows
  • Removed legacy: api_ci.yaml (TS), api_cd.yaml (TS), stripe_backfill.yaml, k6.yaml
  • Renamed/updated: ai_ci.yaml → api_ci.yaml and ai_cd.yaml → api_cd.yaml
    • Triggers: apps/ai/** → apps/api/**
    • CI: cargo check -p ai → cargo check -p api
    • CD: doxxer.ai.toml → doxxer.api.toml; concurrency ai-fly-deploy → api-fly-deploy
    • Deploy: fly deploy now expects apps/api/fly.toml (see Notes)
• Docs
  • apps/web/content/docs/developers/1.env.mdx: updated section heading/paths to apps/api and removed reference to apps/api/package.json
  • apps/web/content/docs/developers/5.run.mdx: API run command now cargo run -p api
• Cleanup
  • pnpm install (lockfile regenerated)
  • dprint fmt
  • cargo check -p api (Rust API crate) passed locally

Review & Testing Checklist for Human (5)

• Workflows: Double-check .github/workflows/api_ci.yaml and api_cd.yaml
  • Paths include apps/api/** and relevant crates (llm-proxy, transcribe-proxy)
  • CD uses doxxer.api.toml with tag prefix api_v; concurrency group is api-fly-deploy
  • Deploy command uses apps/api/Dockerfile and expects apps/api/fly.toml (see Notes)
• Fly config: Confirm desired deployment strategy
  • We preserved the old hyprnote-ai config as apps/api/fly.ai.toml
  • api_cd.yaml now points to apps/api/fly.toml by design; create a new apps/api/fly.toml via fly launch for the new API when ready, or update CD to point to fly.ai.toml if you want to keep existing infra
• Dockerfile correctness: Validate apps/api/Dockerfile
  • sed workspace members target apps/api
  • cargo chef cook/build use -p api
  • runtime copies /app/target/release/api and ENTRYPOINT is /usr/local/bin/api
• Lingering references: Scan for any remaining apps/ai paths or -p ai usage (I updated bacon.toml, openapi-ts, Dockerfile, docs, and workflows; grep found no remaining refs in repo content except those intentionally preserved)
• Docs: Verify the updated developer docs read correctly for rust-based API (env.mdx and run.mdx)

Recommended test plan:

1. Local check
   • cargo check -p api
   • cargo run -p api (ensure it starts on port 3001 as before)
2. Client generation
   • pnpm -F api-client2 build (verifies openapi-ts input path now points to apps/api/openapi.gen.json)
3. CI smoke
   • Ensure api_ci runs on this PR (apps/api/** touched) and passes cargo check
4. CD dry-run (optional)
   • Decide whether to create apps/api/fly.toml (new API deployment) or temporarily point CD at apps/api/fly.ai.toml if you want to reuse hyprnote-ai infra
   • If creating a new Fly app, run fly launch in apps/api, commit fly.toml, and re-run api_cd workflow

Notes

• The stripe Taskfile forwarding to 8787 vs. Rust API on 3001 remains as-is; adjust separately when wiring webhooks to the new API if needed.
• api_cd.yaml currently points to apps/api/fly.toml (intentionally). You’ll need to create this before running CD for the new API deployment. The previous hyprnote-ai config is preserved at apps/api/fly.ai.toml.
• Full workspace cargo check failed locally due to missing system library libpipewire-0.3 in this environment. cargo check -p api succeeded.
