Parallelize the serialized server test suite

[patroza]

Summary

• remove the blanket single-worker constraint from all 197 server test files
• cap file workers at four to retain predictable load for git, SQLite, temp-worktree, and orchestration tests
• keep test isolation and execute every assertion normally

Evidence

The Vite+ migration introduced fileParallelism: false, making the server package dominate the workspace critical path. Profiling shows the reported import time is aggregate module evaluation serialized behind one worker—not 90–130 seconds of TypeScript transformation.

Run	Wall time	Result
Full workspace before	114.77s	passed
Server before	97.10s	passed
Server, four workers #1	25.18s	passed
Stress #2	25.23s	passed
Stress #3	25.22s	passed
Stress #4	25.16s	passed
Full workspace after	41.93s	passed

That is a 74% reduction for the server package and 64% for the complete local workspace suite. All runs executed 194 passing + 3 skipped files and 1,793 passing + 11 skipped server tests.

--no-isolate was also tested and abandoned after making no progress for more than 137 seconds. This PR does not cache test outcomes or weaken isolation.

Verification

• four repeated server-suite stress runs with four workers
• complete pnpm exec vp run test workspace run
• focused format/lint check for apps/server/vite.config.ts
