fix(cli): bundle patched diff parser dependency

[juliusmarminge]

Summary

• bundle @pierre/diffs into the published t3 CLI bundle
• expose and test the server pack dependency predicate so the patched Pierre subpath stays bundled

Why

The workspace uses a pnpm patch to add @pierre/diffs/utils/parsePatchFiles to the package exports map. Local builds work because that patch is applied. Published npm users install vanilla @pierre/diffs, so the current t3@nightly bundle crashes immediately with ERR_PACKAGE_PATH_NOT_EXPORTED when Node resolves the external subpath import.

Bundling @pierre/diffs keeps the source subpath import, preserves the React Native-compatible import strategy, and removes the external runtime dependency on the patched exports map.

Validation

• vp test apps/server/src/packageConfig.test.ts apps/server/src/checkpointing/Diffs.test.ts
• vp run --filter t3 build:bundle
• node apps/server/dist/bin.mjs --help
• checked apps/server/dist/bin.mjs has no external @pierre/diffs import
• vp check
• vp install to repair a partial local install from filtered deploy probes
• vp run typecheck

Note

Low Risk
Packaging-only change to dependency bundling; reduces runtime failure risk for published CLI users without touching auth or data paths.

Overview
The published t3 CLI was resolving @pierre/diffs at runtime using a pnpm-patched subpath that npm installs do not export, causing immediate ERR_PACKAGE_PATH_NOT_EXPORTED crashes.

This change always bundles @pierre/diffs into the server pack output alongside existing internal prefixes, and replaces the inline alwaysBundle predicate with an exported shouldBundleCliDependency helper backed by bundledPackagePrefixes so the bundling rule is explicit and testable.

Note

Bundle @pierre/diffs dependency in CLI packaging

Adds @pierre/diffs to the list of prefixes in vite.config.ts that are always bundled during CLI packaging. Extracts the prefix list into a bundledPackagePrefixes constant and a shouldBundleCliDependency helper, replacing the previous inline predicate.
