Function reinstall_tracked_agents

src/update_cmd.rs:291–307

Re-runs full `install()` + `post_install()` for every tracked agent so tool permissions, hooks, and MCP config stay in sync with the running binary — a superset of `refresh_generated_plugins`, which rewrites generated artifacts only. Mirrors the canonical `handle_reinstall_command` (global scope: `project_root: None`). Continues past a failing agent; returns [`ReinstallOutcome::PartialFailure`] li

/// resolved, no install runs and a descriptive failure is reported so the
