feat(bilibili): add following adapter — get user's followed accounts

Discovered via Playwright MCP Bridge workflow (CLI-CREATOR.md):
 - Navigate to space.bilibili.com/{uid}/fans/follow
 - Sniff network: GET /x/relation/followings (Cookie-tier, no Wbi needed)
 - Verify API response: total=1342, fields: mid/uname/sign

Also fixed .d.ts loading bug in build-manifest.ts and engine.ts:
 - build-manifest now scans .js files in dist/ (not .ts)
 - engine.ts skips .d.js declaration stubs
