Fixes STA-1513 (#7848). A second launch that loses the single-instance lock logs the failure and calls app.quit(), but app.quit() is asynchronous: the process still reaches the app.whenReady() handler and runs the full startup path. That path publishes orca-runtime.json (runtimeRpc.start) and the agent-hooks endpoint file (startTerminalRuntimeStartupServices), overwriting the live instance's records with the transient's own pid and socket. The transient then exits, leaving metadata pointing at a dead pid while the real app is still running — so `orca status` reports stale_bootstrap and terminal commands fail with runtime_unavailable. `orca open` relaunches, briefly repairs, and the next transient clobbers it again, which is the ready -> stale_bootstrap flap. The module-level guard already skips userData side effects when the lock is lost, and single-instance-lock.ts documents preventing exactly this clobber, but the guard stops at line 671 while the ready handler runs unconditionally. hasSingleInstanceLock was never consulted again. Bail out of the ready handler when the lock was lost, before any side effect. hasSingleInstanceLock is false only when the lock was genuinely lost and app.quit() has already been called, so no legitimate startup is skipped; dev skip and the macOS bypass both resolve to true. Not addressed here: an already-clobbered record still needs an Orca restart to be rewritten. With the clobber prevented, a stale record now only follows a genuine crash, where stale_bootstrap is the correct report. Adds a regression test asserting the bail precedes every side effect in the handler; verified it fails without the guard.
