fix(hooks): prevent SSRF via URL scheme validation and extend disable mechanism to HTTP hooks

- Restrict HTTP hook URLs to http: and https: schemes only (blocks file://, data://, ftp://)
- Extend hook disable config to cover HTTP hooks by matching against hook URL identifier
- Update all 5 hook executors (pre-tool-use, post-tool-use, stop, pre-compact, user-prompt-submit)
- Add 6 new tests for URL scheme validation (file, data, ftp rejection + http, https, invalid URL)
