Part of #418. The agent-host rewrite is split out to #1661.

What changes

• electron/main.js now calls module.enableCompileCache() before any other require. On warm launches the store/runner/ipc/services require graph drops from about 80 ms to about 70 ms (Electron 35.7 / Node 22.16). Node keys cache entries by file content and runtime version, so an app update cannot load stale bytecode. NODE_DISABLE_COMPILE_CACHE=1 turns it off.
• electron/smoke.js gains a startup gate. It times process start to the first React mount and logs it as {"step":"startup","ms":…}. Smoke fails if that takes longer than SOLENTA_STARTUP_BUDGET_MS (default 15 s). It runs on the macOS, Windows and Linux smoke jobs.

Already on main from earlier work

• Boot data: Interaction polish batch: animation rule, render-first, white-flash audit, caffeinate, cost rounding #364 src/bootSnapshot.ts.
• Lazy transcripts: Performance round: measure on real data, then fix the top costs #1475.

Verification

• Smoke passed twice in a CI-comparable env (no CODER_* vars, node-only PATH), with startup at 1148 ms and 1835 ms.
• With SOLENTA_STARTUP_BUDGET_MS=300 the smoke run exits 1 with startup took 1352 ms, over the 300 ms budget.
• The electron tests that read main.js/smoke.js pass: 193 pass, 0 fail.

Limits

• The 15 s budget only catches multi-second regressions, because CI runners vary about 3x. Tighten it once the CI logs give real per-OS numbers.
• Smoke boots its own harness, not main.js, so main-only boot work (memory supervisor, schedulers) is not timed.
