+ * Project identity resolution for the Mem0 OpenCode plugin.

+ * The project id (`app_id`) scopes memories to a repo. We derive it from the
+ * git remote so it is stable across clones, worktrees, and sub-directories —
+ * falling back (in opencode-mem0.ts) to the git repo root dir name, then the
+ * cwd. Keeping the parser pure makes the tricky remote formats testable.

+ * Handles https, scp-style ssh, custom ssh host aliases (e.g.
+ * `git@github.com-work:owner/repo.git`), an optional `.git` suffix, and a
+ * trailing slash. Returns null when no owner/repo can be found.
