fix(linkedin-studio): S29a terminology-scrub — "thought leadership" → neutral (commands/)

First sub-pass of the S29 plugin-wide terminology scrub: the banned brand phrase
"thought leadership" (FORM A) removed from the user-facing command surface. 15 in-file
phrase occurrences across 9 commands re-sourced to neutral wording (post, video, strategy,
batch, setup, react, outreach, onboarding, monetize) — e.g. "thought leadership content
creator" → "content creator", "Select Thought Leadership Angle" → "Select Content Angle",
"Build thought leadership & authority" → "Build authority & influence", onboarding guide
→ "LinkedIn Studio onboarding guide".

Scope (operator-set): FORM A only. FORM B ("thought leader" as role, incl. the buzzword
denylist at post.md:134) left untouched. The 11 filename pointers to
references/thought-leadership-angles.md deferred to S29e (atomic rename + pointer update);
competitive.md/pipeline.md carry only pointers and are untouched here. Pure history
(CHANGELOG, docs/**) left intact per "history → git".

Verify: assertive non-filename FORM-A in commands/ = NONE; FORM B count unchanged (15);
diff +15/-15 across 9 files (1:1); gate 81/0/0; counts 29/19/26/6 + v0.5.0 unchanged.
