player: raw scenario replay without manual cleanup (#14)

First time box-v6.yaml (raw recorder output, 676 lines) replays end-to-end
and actually creates a Box in the SUT — no AI post-editing of target paths
or offsets required. This is the counterpart to #13's recorder-side fixes:
the player now absorbs the remaining record→replay gaps instead of demanding
a hand-cleaned scenario.

Changes (all in Recordingtest.Player):

- PlayerEngine: null-target fallbacks
  - Type with null target → host.Type() against current focus
  - Click with null target + raw_coord → click at screen-absolute raw_coord
  - Other null targets still skipped
- PlayerEngine: strip leading alt+tab hotkey steps (recording-startup noise
  that fights the player's own foreground switch)
- PlayerEngine: preserve recorded inter-step timing, clamped 150ms–3s,
  routed through new IPlayerHost.Delay so the engine itself stays Sleep-free
  (keeps the existing "no fixed sleep" DoD test passing)
- PlayerEngine: per-step console log for live debugging
- UiaPlayerHost: BringSutToForeground() — SetForeground + Focus + 600ms
  settle, called from Program.cs before engine.Run
- Step model: add RawCoord (int[]) and Ts (long?) fields, auto-mapped from
  YAML raw_coord / ts keys

Tests updated:
- PlayerEngine_NullTarget_SkipsWithoutCalling → _Fallback_Issue14
  (verifies the new Click-with-raw_coord and Type behavior)
- FakePlayerHost (both player.tests and runner.tests) implement Delay

Live smoke: box-v6.yaml raw replay produced the expected Box geometry on
the 2nd attempt; 1st attempt dropped the initial "BOX" keystrokes, tracked
as a follow-up (foreground settle is still threshold-sensitive at 600ms).
