docs(commercial): one source of truth for the money — prices, entitlement, channels

The commercial plan was spread over five documents written in five different weeks,
and they contradicted each other: product.md sold the Store, decisions.md called the
Store dead then re-opened, Distribution.md (736 lines) still described Polar as a
download host, MARCOM.md quoted "no subscription" next to a paid tier, and README.md
promised "free forever". An outsider could not tell what ships.

docs/ai/commercial.md is now the only place money is decided: free = whole app at a
921,600 px / 30 fps output profile covering the recording as well as the stream; Pro =
$10/mo or $400 lifetime through Polar, key bound to the buyer's YouTube channel ID via
a claim page, 2 activations, 7–14 day lease with offline grace, fail closed, never
downgrade a running stream; one portable zip + winget primary, Steam and the Store
parked; Azure Trusted Signing (~$9.99/mo), no EV; Founding 200 promo; ~$135/yr costs;
anti-piracy posture and what is permanently rejected.

Everything else now points at it instead of restating it:
- product.md — money sections replaced with pointers; packaging rewritten to
  winget-first, Store parked; signing updated to Trusted Signing.
- decisions.md — graveyard with cause of death for free-forever, the Store ordering,
  the updater, and the 2026-10-30 reversal of the quality-ceiling rejection.
- Distribution.md — rewritten to release mechanics only (artifact, GitHub Releases,
  winget manifest, signing, checklist, takedown): 736 → 120 lines.
- TASKS.md — TASK 54 rewritten, TASK 48's route settled, TASK 10 superseded, five new
  rows (entitlement seam, output-profile gate, licence UI, system messages, packaging).
- README.md — "free forever" replaced with the real split.
- capture.md — obs-backgroundremoval is GPL-3.0 and so licence-INCOMPATIBLE since the
  proprietary EULA; the old "compatible" line was falsified by that change.
- TASKS/task-10, task-48, task-51, task-54 — superseded-banner at the top of each, so
  none of them reads as current policy.
- HANDOFF.md — rewritten: plan settled, next code unit is the entitlement seam.

MARCOM.md and MONETIZATION.md (gitignored) were corrected in place: policy pointer at
the top of each, the flash removed from every live claim, the Polar fee break-even
corrected to ~$900/mo, and the projections flagged as written against a dead model.
