PiTTy v0.5.10

PiTTy v0.5.10 adds a Memory entry to Settings, so the memory browser is reachable on terminals where Ctrl+M can't be distinguished from Enter.

Memory Access from Settings

Added a "Memory" entry to Settings (Ctrl+X), so the memory browser (pi-hermes-memory) is reachable without Ctrl+M. Several terminals — notably Konsole without the Kitty keyboard protocol enabled — send Ctrl+M as a plain Enter keystroke, so the shortcut previously looked like it "did nothing" there.
Escaping out of Memory when opened from Settings now returns to the Settings root list instead of leaving the dialog stuck open or dropping focus back to the main chat.
Updated the in-app /help text and docs (README.md, docs/USAGE.md) to point at Settings > Memory (or /memory) as the reliable fallback when Ctrl+M isn't distinguishable from Enter on a given terminal.
