* fix(git): reconcile pull requests after branch changes
Treat persisted change-request metadata as a branch-bound hint and prefer current tracking configuration when it identifies the checked-out branch.
* fix(git): preserve enterprise fork identity
Use branch-bound metadata to supplement the owner when explicit tracking points at the same head on a self-hosted remote.
* fix(git): honor local branch upstreams
Treat Git remote dot with a merge ref as explicit current tracking so stale PR metadata cannot override a local upstream.
* fix(git): own change request branch bindings
Centralize persisted hint validation and rebinding so renames preserve change request identity while switches invalidate it, including normalized legacy Enterprise owners.
* fix(git): preserve PR identity through workspace renames
Resolve the backing worktree root during rename without adding a Git call, and retain fork owner identity from explicit same-name tracking configuration.
* fix(git): trust current enterprise fork identity
Explicit tracking now derives repository identity from the current remote path, so stale checkout metadata cannot override a repointed fork.
* fix(git): recognize enterprise repository aliases
GitHub repository identity is case-insensitive. Normalize equality checks so differently cased aliases cannot turn base tracking into a fork lookup.
* fix(git): reject ownerless legacy fork matches
Owner-qualified legacy hints only belong to their historical owner-prefixed branch names. A later ownerless branch reusing the same head must resolve from current Git state instead.
* fix(git): keep fork feature lookups local
A feature branch may track the upstream base branch for ancestry even when origin is a fork. Only treat that cross-repository base ref as PR identity when the local branch name identifies the tracked head.
