feat(claudbg-x45o): sessions list scopes to current project by default

Add --scope=project|user flag to `sessions list` (default: project).
When project scope is active, only sessions whose project_path matches
the current working directory are shown. Use --scope=user to see all.

 When run inside a project directory, `claudbg sessions` should only list sessions for that project (similar to how `claude /continue` lists sessions for that project). Override with `--scope=[user|project|local]` — default is 'project'.
+
+## Summary of Changes
+
+Added `SessionScope` enum (`Project` | `User`) to `src/cli.rs`.
+Added `--scope` flag to `SessionsCmd::List` with default `project`.
+Updated `sessions::list()` signature to accept `scope: SessionScope`.
+When scope is `Project`, resolves the current working directory and filters raw rows to only include sessions whose `project_path` exactly matches the CWD. Scope `User` shows all sessions (previous behavior).
