fix(desktop): independently replace cursor values

[Sun-GLiang]

Summary

• replace the cursor glyph, motion configuration, close-enough gate, normalized scorer, and terminal heading with the independently derived values published for legal: independently replace the cursor values recovered from a proprietary binary #3293
• preserve the Maka candidate family and surrounding behavior while enforcing the nine-candidate budget, action hotspot, and 2100 ms presentation deadline
• synchronize PiP/status assets and rewrite cursor provenance around the public clean-room derivation
• keep overlay readiness tied to real animation frames, disable background frame throttling, and invalidate stale presentation state on reset

Clean-room provenance

The complete independent derivation was published before the replaced implementation and provenance values were inspected:

Closes #3293

Verification

• npm --workspace @maka/desktop test — 1054/1054 passing
• npm --workspace @maka/desktop run typecheck
• npm --workspace @maka/desktop run build:overlay
• npm run lint
• npm run format:check
• deterministic status-icon regeneration and PiP source/build comparison
• 1×/2× light/dark complex-background visual QA
