Function parseGitPushBranch

src/tools/shared/gitOperationTracking.ts:93–98

* Parse branch name from git push output. Push writes progress to stderr but * the ref update line ("abc..def branch -> branch", "* [new branch] * branch -> branch", or " + abc...def branch -> branch (forced update)") is * the signal. Works on either stdout or stderr. Git prefixes each ref line

(output: string)

 * with a status flag (space, +, -, *, !, =); the char class tolerates any.
