* fix: migrate eslint config for eslint 10 compatibility

- Migrate from .eslintrc.js (legacy) to eslint.config.mjs (flat config)
- Upgrade @typescript-eslint packages from v6 to v8
- Add @eslint/compat to fix eslint-plugin-security with ESLint 10
  (context.getSourceCode() removed in v10)
- Add @eslint/js, globals, and typescript-eslint packages
- Remove eslint-plugin-rulesdir (use native flat config plugin)
- Rename eslint-disable comments: rulesdir/ -> local/
- Update no-var-requires -> no-require-imports (renamed in ts-eslint v8)
- Update RuleTester to use languageOptions (flat config format)
- Remove --ext .ts from lint script (removed in ESLint 9+)
- Disable new ESLint 10 rules (no-useless-assignment, preserve-caught-error)
  to maintain parity with previous config; enable in follow-up PR
- Add .npmrc with legacy-peer-deps for @typescript-eslint peer dep
  compatibility (ESLint 10 support pending in typescript-eslint)

* fix: drop Node 18 from CI matrix (ESLint 10 requires Node >= 20.12)
