Adds diagnostic navigation to the TUI/editor surface. Reuses the
existing `pmacs.diag.next` / `previous` walkers (which already wrap
around) and the cross-file jump ring so `M-,` returns from a
diagnostic jump just like an LSP definition jump.
Surface:
* `pmacs.command.define { name = "diag.next" / "diag.previous" }`
* `pmacs.keymap.bind { sequence = "M-g n" / "M-g p" }` — Emacs's
`next-error` / `previous-error` chord.
The command walks the diag store for the active buffer's attached URI,
falls back to a status-line message ("no LSP server" / "no diagnostics
in buffer") rather than faulting when there's nothing to jump to. On a
hit it pushes the jump ring, moves the cursor via `pmacs.editor` motion
primitives (so every overlay observer sees the navigation), and sets a
status line of the form `diag (warning): ...`.
Test verifies the commands are registered, bindings exist, and the
no-server status path lands.
