Add a repo-level fetch cache keyed by repo path so that when multiple branches share the same local .git directory, a single git fetch satisfies all of them within the TTL window. Implements "Option C" from the plan: the repo-level TTL gates the "did we recently talk to the remote?" decision, while per-branch refspec tracking ensures any new refspecs get a cheap narrow fetch (without --prune) when the repo is already fresh. Remote projects continue using per-branch caching unchanged. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> Signed-off-by: Matt Toohey <contact@matttoohey.com>
Cover normal Unix path, Windows-style path with colons, branch==base edge case, non-local prefix rejection, and too-few-segments rejection to lock in the double rsplit_once parsing invariant.

On a full fetch (TTL expired, --prune), replace the repo-level fetched_refspecs set with exactly the needed refspecs rather than extending the existing set. This prevents unbounded growth from branches that were opened and later closed. Narrow fetches (within TTL, filling gaps) continue to extend additively as before.
