fix: clean plugin test temp directories

[thunderavi]

Summary

• Move plugin/reload test temporary directories from the repository root to os.tmpdir().
• Clean the generated plugin test directories with fs.rmSync(..., { recursive: true, force: true }).
• Ignore future generated plugin temp folders and tsconfig.tsbuildinfo.
• Remove already tracked generated tmp-easy-plugin-*, tmp-easy-plugin-reload-*, and tsconfig.tsbuildinfo files.

This is a clean maintainer version of the useful temp-directory cleanup approach from PR #2, without the unrelated dependency, TypeScript, frontend, or CI changes from that branch.

Closes #1

Testing

• npm test -- tests/unit/plugins.test.js --runInBand
• npm run verify
• npm run typecheck
• npm test -- --runInBand
• npm run validate:production
• npm run lint:easy
• npm run test:coverage

Also verified that running the plugin tests creates 0 new tmp-easy-plugin-* directories in the repository root.

Pull request overview

This PR prevents repository-root pollution from plugin unit tests by moving their temporary plugin directories to the OS temp directory and ensuring they are always deleted after each test run. It also cleans up already-tracked generated temp folders and ignores future generated artifacts (including TypeScript build info).

Changes:

• Update plugin unit tests to create temp plugin/reload directories under os.tmpdir() and delete them in finally blocks via fs.rmSync(..., { recursive: true, force: true }).
• Add .gitignore entries for tmp-easy-plugin-*, tmp-easy-plugin-reload-*, and tsconfig.tsbuildinfo.
• Remove previously committed generated temp plugin directories and tsconfig.tsbuildinfo from the repository.
