Default new worktrees to the upstream branch (#2848)

* fix(workspaces): default new worktrees to upstream refs

Use the daemon-resolved upstream as the untouched starting ref so unpushed local commits do not leak into new workspaces. Preserve exact base identity for fork remotes while keeping local-first behavior across version drift.

* fix(workspaces): preserve exact base refs in git actions

Resolve accepted display aliases back to the stored ref before comparisons and updates. Fail closed when a non-origin remote base has no explicit mutable merge target.

* fix(workspaces): reject conflicting qualified base refs

Display aliases remain accepted for compatibility, but a qualified ref carries remote identity and must not be canonicalized to a different stored upstream.

* test(server): make upstream fixtures portable

Keep the checkout-status fixture aligned with the optional upstream field, and select main explicitly when cloning a bare test remote whose default HEAD varies by platform.

* fix(workspaces): preserve exact upstream refs

Qualified remote refs now fail closed when pruned instead of switching lineage. Metadata accepts Git-valid upstream names rather than applying a narrower character whitelist.

* fix(workspaces): preserve qualified local base refs

Local tracking branches are exact upstream identities too. Keep heuristics only for legacy unqualified metadata so origin cannot replace a stored refs/heads base.
