v1.1.2 — v1.3 hardening for client launch

Pre-client-launch hardening. The v1.3 core is unchanged and verified accurate against the live docs, the real implementation, and the internal docs.

Changed

• v2 section reduced to a drift-proof pointer to https://api.qapla.dev/v2/ — removed specifics that conflicted with the deployed API (auth field, version label, scopes, endpoint table, "preview" wording). The skill targets v1.3; for v2 follow the live docs.

Fixed

• webhooks.md: corrected the return-webhook refundMethodCode example ("ORIGINAL" → "0001").

Removed

• Internal docs/merge-plan.md; sanitized internal references in evaluation/scenarios.md.

Wired

• trackingbytimeframe.md and apivirtual.md added to the reading order in SKILL.md / AGENTS.md / the Cursor rule.
