add tag support, initially readonly

CHANGELOG.md

 ### Added
 - Git remotes in the status bar, with push & fetch commands.
 - "Create branch" command on revisions. 
+- Display Git tags (readonly; they aren't really a Jujutsu concept).
 - Display edges to commits that aren't in the queried revset, by drawing a line to nowhere.
 - Detect changes made by other Jujutsu clients and merge the operation log automatically.
 - Window title includes the workspace path (when one is open).

 * bug: proper fix for https://github.com/tauri-apps/tauri/issues/9127 (currently worked-around via fork; fix may be in beta12, or it might not work)
 * bug: open menu command sometimes opens multiple dialogues
+* bug: no CLI output on windows
 * edge case: mutations can fail due to ambiguity due to other writers; this should update the UI. maybe use a special From on resolve_change
 * perf: optimise revdetail loads - we already have the header
 * perf: better solution to slow immutability check - jj-lib will have a revset contains cache soon
