fix(linkedin-studio): S7 harden batch — format-aware length band on per-post quality check

S7 close-out (1 edit / 1 command-file · lint 81/0 · counts 29/19/26/6):
- batch.md:95 Step-3b Quick Quality Check: replace vague "Character count in range" with a format-aware band (standard 1,200-1,800 · quick 150-500 · carousel/video caption per that format) — the old line named no band, and the 3a structure (:88-92) sums to 960-1640, under the 1,200 standard floor, so a ~1,000-char standard post passed "in range" unflagged

Axis-c (length band) closed; axes a/b/d PASS. Class: hybrid guided/stateful + post-emitting per post (each of 3-5 drafts is a feed post). Buzzword (:98) + no-body-link (:97) already present — the gap S2-S6 found is already closed in batch. Wiring verified: trend-spotter + content-planner resolve; all 5 node helpers (queueUpcoming/queueAdd 8-arg/queueFormatSummary/generateIcalFromQueue/writeIcalFile) export with matching signatures. 3 deferrals (3a single-structure vs mixed-format promise · no per-post differentiation gate by design · weekly_goal-unset micro-fallback). Local-only per push policy.
