test(repo): execute packed subpaths

[jrusso1020]

What

Execute every promised packed subpath in clean Node and browser consumers.

Why

Manifest generation alone cannot prove that an exported subpath installs, resolves peers, or bundles in its declared environment.

How

Install packed tarballs, import all Node promises, typecheck consumer code, and run a Vite browser build according to descriptor environments.

Test plan

• 94 packed exports resolved; 89 Node exports executed; TypeScript and Vite consumer validation
• Stack-wide lint, format, build, typecheck, and relevant integration gates

Fixed the exact-head Build failure in 634cd71. The packed browser-consumer check had classified parsers Node-only ./ff-binaries and ./asset-resolution exports as browser-safe, so Vite attempted to bundle their fs, path, and child_process imports. Their descriptors now correctly declare bun,node only.

Validated with bun run sync:package-subpaths, bun run check:package-subpaths, and bun run verify:packed-manifests: 12 manifests are publish-safe; the packed consumer resolves 100 exports, executes 95 Node exports, and passes TypeScript/Vite resolution plus CLI startup. Restacked and republished #2169–#2174; fresh exact-head CI is running.

Exact-head review completed at 634cd719a26742ae92a33c38348da4d8fd37fc52.

The packed-contract verifier now exercises the actual tarballs in environment-appropriate consumers: Node exports are resolved and executed, while browser-declared typed exports are kept live through namespace bindings and bundled with Vite. That specifically prevents sideEffects: false from making the browser check vacuous.

The parser correction is consistent with the implementation: ./ff-binaries and ./asset-resolution import Node built-ins, so declaring them Bun/Node-only fixes the root contract mismatch. The descriptor-driven checks, focused 9/9 test suite, clean diff check, zero unresolved threads, current ancestry, and exact-head CI are all green.

Non-blocking nit: the PR description's 94/89 export counts are stale; the exact-head run reports 100 resolved and 95 executed.

Verdict: APPROVE
Reasoning: The packed-contract gate now detects both published export/alias drift and Node-only entrypoints incorrectly advertised to browser consumers, with meaningful execution/bundling coverage and green exact-head evidence.
