/**
|
|
* Parses a GitHub repository URL of the form
|
|
* https://github.com/<owner>/<repo>[.git][/][?query][#fragment]
|
|
* (scheme and `www.` are optional).
|
|
*
|
|
* Returns `{ owner, repo }` on a match, or `null` for empty input or any URL
|
|
* that doesn't match the repo pattern. The input is trimmed before matching;
|
|
* a `.git` suffix and a single trailing slash are tolerated and stripped, and
|
|
* an optional `?...` query string or `#...` fragment is allowed before EOL so
|
|
* canonical share URLs like `github.com/owner/repo?tab=readme` parse cleanly.
|
|
*
|
|
* PR URLs (`/pull/<n>`) intentionally do NOT match here — callers that need
|
|
* to recognize PRs layer their own regex on top before falling back to this
|
|
* helper.
