Game Profile brain: Pulse director + the four dials + GameWorld

[prakashUXtech]

Stacks on the graduation PR. Adds the runtime brain: a drama director, the evidence-derived dial machinery, and the GameWorld composition that emits the engine-neutral session event stream.

What's in here

• Pulse director (0ea2e3d): L4D-style pacing engine — per-player intensity, BUILD_UP → PEAK (beat-counted) → FADE → RELAX cycle, paces event frequency not amplitude, a mandatory relax window that blocks escalation even under max heat, a yes-and rule that never vetoes a player action, and an enjoyment-signal hook for future telemetry.
• Dials (2734ba4): Challenge / Progress / Choice / Spark as composable 0-1 dials. The design rules are enforced mechanically: Progress must advance on a failed beat (failure-as-progression), Choice never returns fewer than two viable actions, Spark forces variation after K same-kind beats, Challenge maps monotonically onto the director's thresholds.
• GameWorld (73846a7): composes kernels + director + dials + cost meter; beat() runs the loop and appends session events (beat / speech / grudge_change / bond_change / director_phase / cost_tick) to a jsonl stream — the renderer protocol. Counter-based time, no wall clock, replay-safe.

Tests

40/40 (8 director + 8 dials + 6 world + 15 kernel + 3 demo-server from the next PR's base). All deterministic, no LLM, no network.
