chore: bump pnpm to v12

[rozenmd]

Summary

• pin pnpm 12.3.4 for local and CI installs
• update Vite+ to 0.3.1 for pnpm 12 package-manager support
• migrate the removed onlyBuiltDependencies setting to the pnpm 12 allowBuilds policy
• update the lockfile and apply the new formatter output

Validation

• vp install --frozen-lockfile

• pnpm typecheck

• pnpm test (1,308 tests)

• pnpm lint

• pnpm format:check

• Reviews

• bonk has reviewed the change

• automated review not possible because: this is a toolchain migration with generated lockfile and formatter output

• Tests

• Tests included/updated

• Automated tests not possible - manual testing has been completed as follows: not applicable

• Additional testing not necessary because: the existing install, typecheck, test, lint, and format checks cover this migration

Review notes

• Confirming PR chore: bump pnpm to v12 #794 and inspecting its existing reviews, changed configuration, lockfile changes, and applicable workspace guidance.
• Verified the target is PR chore: bump pnpm to v12 #794 at the supplied head commit, with no prior reviews. The configuration diff is whitespace-clean; next I am checking all package-manager installation paths and the lockfile's pnpm-12 migration records.
• The review environment has neither pnpm nor Node installed, so install/test commands cannot run. I found that pnpm 12 records the package-manager dependency as a separate YAML document at the start of the lockfile; I am verifying this new lockfile format and the build-approval policy against pnpm's documentation and the resolved dependency metadata.
• Verified pnpm 12's documented two-document lockfile format: the added env document correctly pins pnpm@12.3.4. The allowBuilds map preserves the former allow-only policy by allowing workerd and explicitly denying the four other dependency build scripts present in the resolved graph.
• GitHub checks show the install-dependent jobs failing before lint, typecheck, and test run, while static lockfile-structure checks pass locally. I am inspecting the failed CI logs to determine whether the pnpm migration causes the shared setup failure.
• CI logs confirm every install-dependent job fails at vp install --frozen-lockfile with Cannot find binary path for command 'pnpm'. Setup recognizes pnpm 12.3.4 but Vite+ 0.2.6 cannot execute it, so the migration currently blocks the PR's build, docs, preview, format, and changeset workflows.
• Upstream Vite+ 0.2.7 specifically adds support for pnpm 12's native binary distribution; this repository remains pinned to 0.2.6. I will post one inline suggestion on that pin, which addresses the confirmed CI failure.
• Posted one inline suggestion on pnpm-workspace.yaml; it upgrades the Vite+ pin required for pnpm 12 CI installs.

Review notes

• Reviewing PR chore: bump pnpm to v12 #794 at its current head. The prior Vite+ compatibility finding has been addressed by the updated 0.3.1 pins; I’m now checking the complete changed configuration and lockfile resolution.
• I verified the prior inline comment is stale and no additional reviews were published. The current workspace policy explicitly allows only workerd builds and denies the other dependency scripts; the required Kumo changeset is present.
• The regenerated lockfile contains pnpm 12’s package-manager dependency document, resolves the Vite+ 0.3.1 toolchain consistently across all importers, and has no whitespace errors. CI’s format and changeset jobs now pass; the remaining build and docs jobs are still in progress.
• Corepack resolved the declared pnpm 12.3.4 binary, and pnpm install --lockfile-only --frozen-lockfile --ignore-scripts passed its 1,248-entry supply-chain-policy validation without changing the lockfile. The CI build job has also passed; no actionable regressions found.
