Fix published CLI runtime startup

[kingmarh-hash]

Summary

• move fs-extra into runtime dependencies so production installs include it
• resolve the CLI version from the package root package.json instead of dist/package.json

Fixes #114.

Verification

• Reproduced the published wc3maptranslator@5.0.0 failure with a clean npm install --omit=dev followed by wc3maptranslator --version: it failed on missing fs-extra.
• npm test rebuilt successfully and ran 52/55 tests; the remaining 3 failures are existing binary round-trip assertions in TranslatorReversion.test.js unrelated to CLI startup.
• npm pack --json --silent
• Installed the generated tarball in a fresh temp project with --omit=dev; ./node_modules/.bin/wc3maptranslator --version prints 5.0.0.
• npm ls fs-extra --all shows wc3maptranslator -> fs-extra@11.3.5.

Note: npm run lint currently fails on pre-existing no-explicit-any errors in src/CommonInterfaces.ts; this PR does not touch that file.
