feat: enable Linux PATH inheritance for autostart & extend loginShellPath to Linux (#11372)

Merged via consolidated batch validation. Fixes autostart on Linux failing to inherit the user's shell PATH (CLI-dependent features like Kiro's Google OAuth broke). Resolved a conflict against a batch sibling in bin/cli/commands/doctor.mjs (kept the more complete prebuilds-aware candidate list) and setup-claude.mjs (formatting only). Own test (login-shell-path-3321.test.ts, 10/10) passes + typecheck:core clean. Thanks!
