Documentation and API behavior

• Quickstart: API key creation is documented as Dashboard-only; removed references to a non-existent Public API endpoint for creating keys.
• 402 Payment Required: Documented in Authentication and Error Handling. Described payment_required code, redirect_url, and reason (e.g. trial_not_started, trial_expired, insufficient_credits).
• Error responses: Request validation (422) now returns the same Truedy envelope (error + meta) as other errors. Rate limit (429) responses now include meta.request_id and meta.ts.
• Rate limits: Documentation updated to match implementation: per-minute only (default 100), no per-hour/per-day tiers, no rate limit headers; use 429 body details.limit and details.reset_at.
• OpenAPI: Added 402 to standard response codes. Examples fixed: system_prompt (not instructions), meta.ts and meta.request_id (not timestamp/count), snake_case error codes (validation_error, unauthorized, etc.).
• Pagination: Clarified offset-based vs page-based pagination; contacts list documented as page-based (page, limit, total, pages).
• Webhooks: Documented payload shape, X-Truedy-Signature / X-Truedy-Timestamp, HMAC-SHA256 verification, event_id/dedupe, and retry behavior. Configuration stated as Dashboard-only.
• Versioning: Added versioning and changelog pages.
