fix(linkedin-studio): S28 ref-consistency B — format magnitudes → SSOT

Browse source 
Reconcile commands/video.md + references/linkedin-formats.md to the algorithm-signals SSOT
in one pass (20 edits/2 files). The unsourced "30% completion rate or zero distribution"
gate (7x) → "completion/dwell is a ranking input; shorter completes better; no published
hard completion gate". The 6 S27-folded link-penalty lines → "correlate with lower reach"
(incl. heading "The External Link Penalty" → "External Links and Lower Reach"). Six other
unsourced format magnitudes softened to direction-without-number (video 5.60% ER, Live
12-24x, polls 1.64x, 3x shares, Creator-Mode 35%). One internal contradiction fixed (3-sec
= 70% retention contradicted the already-reconciled three-second-folklore note).

Bucket D (this file's non-format coefficients: 47-50% reach-decline, AI-comment -30%/-55%,
hashtag -68%) left intact and deferred to S30, which is re-scoped to cover them + the other
files. Gate 81/0/0; counts 29/19 unchanged.
