Third commit on the B-2 replay screen-takeover redesign. Adds the
ability to pause an in-flight replay, step through it one move at
a time while paused, and resume — both via on-screen buttons
(UI-first contract per CLAUDE.md §3.3) and the optional `Space`
keyboard accelerator.
State shape: a new `paused: bool` field on
`ReplayPlaybackState::Playing`. The `tick_replay_playback` system
skips the `secs_to_next` decrement entirely while `paused` is set
so cursor and timer freeze together — resuming starts the next
move from a full interval. Stepping fires the next move directly
via a new `step_replay_playback` API that bypasses the tick path
and is hard-gated to `Playing { paused: true }` so it can't race
the running tick loop.
Public API additions:
- `toggle_pause_replay_playback(state)` — flips the flag, returns
the new value (or None when not Playing).
- `step_replay_playback(state, moves_writer, draws_writer)` —
advances exactly one move when paused; returns true on dispatch,
false on any guard miss.
UI:
- Pause / Resume button next to Stop. Label repaints reactively
via `update_pause_button_label`, which walks `Children` from
the marked button to its inner `Text` so the spawn path doesn't
need a second marker.
- Step button next to Pause. Click fires the next move; while
unpaused the click is a no-op (guarded inside
`step_replay_playback`).
- `Space` keyboard handler reads `Option<Res<ButtonInput>>` and
no-ops when missing — keeps test-app compatibility under
`MinimalPlugins`.
Test coverage: pause-button label truth table, label repaint on
state change, click-toggles-paused, step advances cursor exactly
one with paused flag preserved, step-while-running is no-op,
Space toggles paused flag. 8 new tests (1220 → 1228).
Side-effect: 25 existing `Playing { ... }` construction sites
across `replay_overlay`, `achievement_plugin`, and
`replay_playback` tests gained `paused: false` to satisfy the new
field requirement. Mechanical edit; no behavioral change.

The replay overlay's per-move tick rate has been hardcoded at
REPLAY_MOVE_INTERVAL_SECS = 0.45 s/move since the in-engine
playback shipped. Power users want to scrub faster through older
wins. Adds a Settings slider that tunes the interval 0.10–1.00 s in
0.05 s steps; default 0.45 s preserves existing feel.
Settings.replay_move_interval_secs uses #[serde(default)] so legacy
files load to 0.45. sanitized() clamps out-of-range values.
tick_replay_playback now reads SettingsResource per frame and falls
back to the constant when the resource is absent (test fixtures).
The slider takes effect on the very next playback tick — no need to
restart playback.
Mirrors the existing tooltip-delay slider exactly: SettingsButton::
ReplayMoveIntervalUp/Down variants, the same `slider_row` pattern,
the same per-tick repaint system shape.

Promotes the replay feature from disk-only to a real in-engine
playback path. A new ReplayPlaybackState resource models a three-
state machine (Inactive / Playing / Completed); start_replay_playback
resets the live game to the recorded deal via
GameState::new_with_mode(seed, draw_mode, mode) and a tick system
fires the canonical MoveRequestEvent / DrawRequestEvent for each
recorded move at REPLAY_MOVE_INTERVAL_SECS (0.45s).
The reset path bypasses NewGameRequestEvent because the existing
event always sources draw_mode from Settings — a Draw-1 replay
would silently coerce to Draw-3 (or vice versa) on a player whose
preference doesn't match the recording. Inserting GameStateResource
directly applies the recording's exact draw_mode and sidesteps the
abandon-current-game confirmation modal that would otherwise block
playback.
Recording suppression during playback is non-invasive: a sibling
system snapshots RecordingReplay's length on entry to playback and
truncates the buffer back to that mark every frame while is_playing
or is_completed. game_plugin's recording append paths are
untouched.
Completion lingers for REPLAY_COMPLETION_LINGER_SECS (5s) so the
overlay can show "Replay complete" before the auto-clear flips
state to Inactive.
Six new tests cover the state transitions, tick cadence, canonical
event firing, completion, stop-clears-state, and the
recording-suppression contract.
