v0.10.0

Workspace module resolution, browser stability hardening, and zombie process cleanup

Summary

v0.10.0 adds --resolve-from for workspace module resolution and ships two critical browser stability fixes — zombie server detection with safe process cleanup, and Chrome crash prevention from /dev/shm exhaustion in containers.

Highlights

• --resolve-from CLI flag for workspace module resolution — registers an ESM resolve hook that retries bare-specifier resolution from a specified directory (#178)
• Zombie browser server detection — fast-path /proc status check before health check avoids 2s wasted on dead processes; stale process groups killed only after verifying PID ownership via cmdline check (#182)
• --disable-dev-shm-usage on all Chromium launch paths — Chrome uses /tmp instead of /dev/shm for IPC, eliminating renderer crashes from shared memory exhaustion in containers (#185)
• Transient /json/list failure tolerance — browser server idle monitor now requires 3 consecutive failures before exit; non-OK HTTP responses correctly count as failures (#185)
• Chromium launch args centralized into chromiumArgs() helper; idle poll evaluation extracted into pure evaluateIdlePoll() with 18 unit tests
