update_post

Writeposts:write

Update an editable post (draft/scheduled/error/active). Reconciles platform submissions. A requested platform with no active connection never fails this call either (same as create_post) and the response is `{ status: "no_connection", missingPlatforms, scope, post: { id, status } }` instead of the usual `{ id, status }`. PLATFORM RULES (enforced — violations rejected): Post types: `announcement` works on every platform; `event` and `offer` are Google-only (any social platform ⇒ must be announcement). Caption char limits: google 1500, facebook 30000, instagram 2200, x 280 (X thread mode is exempt from the 280 limit), linkedin 2000, pinterest 500, mastodon 500, bluesky 300. Media (per platform, using each item's `platform`): facebook ≤10 images OR ≤1 video, no mix (carousel = 2–10 images only, per-card headline ≤80 / description ≤200); instagram requires ≥1 media, ≤10 images OR ≤1 video, no image/video mix; x ≤4 images OR ≤1 video, no mix; linkedin ≤5 images OR ≤1 video, no mix; pinterest image-only, exactly 1, required; mastodon ≤4 images OR ≤1 video, no mix. Google event ⇒ eventTitle (≤58 chars) + eventStartAt + eventEndAt (end after start) required. Google offer ⇒ ctaType + ctaUrl required. scheduledFor must be in the future. Drafts (draft=true) skip required-field checks but still enforce all structural checks above.
