T-015: Build Smoke Test — CI Passes on Windows, VST3 DLL Produced, task build Clean

Type: Task | Phase: 0 | Autonomy: agent:review-required
Stack: stack:infra | Version: v0.1 | Iteration: iter-1 | Effort: S (half-day)

⚠️ Scope: Add a build job to the GitHub Actions CI workflow (.github/workflows/ci.yml) that runs task build on windows-latest, verifies the .exe exists and is under 30 MB, and verifies the VST3 bundle exists. This is the Day 1 exit criterion proof. If any prior task left broken code, this job surfaces it.

---

Prerequisites

• T-001–T-014 all merged (or all in status:roadmap with known blockers)
• T-007 merged — Taskfile.yml with task build defined
• T-008 merged — CI workflow exists with check and test jobs

Acceptance Criteria

• New build job added to .github/workflows/ci.yml after test job
• build job runs only on push to main (not on every PR — too slow)
• task build runs: cargo tauri build + cargo xtask bundle synesthesia-plugin --release
• CI step verifies .exe exists at kansas/target/release/synesthesia.exe
• CI step verifies .exe size is < 30 MB (fails if Chromium accidentally bundled)
• CI step verifies target/bundled/Synesthesia.vst3/ directory exists
• Build job result posted as a comment on the triggering commit
• cargo check --workspace and pnpm typecheck still pass

Add to .github/workflows/ci.yml
