chore: add npm homepage and bugs metadata

[wowsofine]

Summary

• add standard npm homepage metadata pointing at the existing README
• add standard npm bugs.url metadata pointing at the existing issue tracker
• leave runtime code, dependencies, version, repository metadata, and package exports unchanged

Verification

npm view rollup-plugin-sourcemaps2@0.5.7 name version homepage repository bugs --json
node metadata smoke check for repository/homepage/bugs
npm pack --dry-run --ignore-scripts
npx --yes pnpm@11.1.0 install --frozen-lockfile --ignore-scripts
npx --yes pnpm@11.1.0 run lint:ci
npx --yes pnpm@11.1.0 run typecheck
npx --yes pnpm@11.1.0 run test
npx --yes pnpm@11.1.0 run build
npm pack --dry-run --ignore-scripts
git diff --check

Notes:

• lint:ci exits 0 and reports an existing Biome schema version info message.
• test exits 0 with 1 test file / 11 tests passed and reports an existing Vite missing source map warning for index.js.map.
• Post-build npm pack --dry-run --ignore-scripts includes the generated dist files.
