TASK-61	Ensure parser utility scripts exit immediately after output	Done		2026-02-16 22:35	2026-02-18 04:11			24000

Description

Update scripts/test-yomitan-parser.ts and scripts/get_frequency.ts so they clean up Electron parser resources and terminate immediately after producing results, avoiding hangs.

Acceptance Criteria

• #1 scripts/test-yomitan-parser.ts exits promptly after printing output.
• #2 scripts/get_frequency.ts exits promptly after printing output.
• #3 Electron-related resources (parser window/app loop) are cleaned up on both success and error paths.

Final Summary

Added deterministic shutdown to both utility scripts. scripts/get_frequency.ts now destroys parser windows in a finally block, calls app.quit() when Electron is loaded, and uses explicit .then/.catch exits so the process terminates immediately after output with correct exit codes. scripts/test-yomitan-parser.ts now mirrors this pattern with runtime cleanup (shutdownYomitanRuntime) and explicit process exit handling.
