feat(10-07): add Replit and CodeSandbox scraping sources

- ReplitSource scrapes /search HTML extracting /@user/repl anchors
- CodeSandboxSource scrapes /search HTML extracting /s/slug anchors
- Both use golang.org/x/net/html parser, 10 req/min rate, RespectsRobots=true
- 10 httptest-backed tests covering extraction, ctx cancel, rate/name assertions
