feat(coding-agent): add named-only filter toggle to /resume picker (#1128)

Adds Ctrl+N toggle to filter sessions by named-only vs all in the /resume picker.

- Add NameFilter type and filtering logic to session-selector-search.ts
- Add toggleSessionNamedFilter app keybinding (default: ctrl+n)
- Show Name: All/Named state in header
- Empty state mentions toggle keybinding as escape hatch
- Export hasSessionName() to avoid duplication

 - Added `rpc-demo.ts` example extension exercising all RPC-supported extension UI methods ([#1144](https://github.com/badlogic/pi-mono/pull/1144) by [@aliou](https://github.com/aliou))

 - Added `PI_PACKAGE_DIR` environment variable to override package path for content-addressed package managers (Nix, Guix) where store paths tokenize poorly ([#1153](https://github.com/badlogic/pi-mono/pull/1153) by [@odysseus0](https://github.com/odysseus0))
+- `/resume` session picker now supports named-only filter toggle (default Ctrl+N, configurable via `toggleSessionNamedFilter`) to show only named sessions ([#1128](https://github.com/badlogic/pi-mono/pull/1128) by [@w-winter](https://github.com/w-winter))
