This upgrades our Effect library from a beta to the newer release-candidate version. The next PRs need it, because Alchemy, the infrastructure tool we're moving to, requires this version.

Why

Layer 1 of the Alchemy migration stack. Every Alchemy v2 build requires effect >= 4.0.0-rc.115; the preview build we're pinning in layer 2 needs rc.117. We're on 4.0.0-beta.93. Doing the upgrade on its own keeps the infrastructure PRs readable.

Implementation

• effect ^4.0.0-beta.93 → ^4.0.0-rc.117 (lockfile pins 4.0.0-rc.117). rc.117 has no runtime dependencies of its own, so the lockfile shrinks.
• .repos/effect now vendors the upstream tag effect@4.0.0-rc.117 from Effect-TS/effect, which is where v4 lives now. The old subtree had been renamed from repos/ to .repos/, so git subtree pull couldn't find it. The old tree is removed in one commit and re-added with git subtree add --squash. HEAD:.repos/effect has the same tree hash as the upstream tag.
• API changes (only 2 files edited):
  • Schema.TaggedErrorClass → Schema.TaggedError in src/features/audio/audioErrors.ts. That one renamed base class caused all 63 type errors across 17 files.
  • onExcessProperty: "preserve" was removed upstream → Schema.StructWithRest(..., [Record(String, Unknown)]) in scripts/share-deployment-bindings.ts. Layer 2 deletes this script.
• Drops the Graphite stacked-PR guidance from AGENTS.md.

Review

• No app behavior changes are expected. Smoke test: import a local MP3 and a FLAC, edit tags, and save. Also do one YouTube or SoundCloud URL import against a dev Cobalt.
• Worth a look:
  • Schema.TaggedError instances now use the tag as name, and toString() reads like a native error (AudioDecodeError: …). Nothing in the repo matches on error names or strings, and all tests pass.
  • decodeWranglerConfig still keeps unknown keys, but the decoded key order changes. Wrangler doesn't care.
• Verified automatically:
  • vp check (0 errors; 59 warnings, the same count as main), bun run typecheck, vp test (661 tests, same as main) and vp build all pass.
  • Playwright on Chromium passes.
  • One Firefox test (metadata-formats.spec.ts:49, the suggestedFilename extension) fails identically on main.
  • WebKit can't launch on the build host because system libraries are missing. It still needs a run in CI or on a Mac.
