fix(linkedin-studio): N1 — prune-regex no-op + dato-uavhengige kalender-fixtures (TDD) [skip-docs]

Browse source 
B-F1 (prod-bug, prune de facto no-op): fjernet `m`-flagget fra Recent Posts-
regexen i `state-updater.mjs`. Med `/m` matchet `$`-alternativet i lookahead
slutten av hver linje, så den late capturen stoppet etter FØRSTE entry-linje;
gamle entries under en fersk (nye prepender øverst) ble aldri skannet/prunet.
Ny regresjonstest (old-under-fresh) rød->grønn beviser mekanismen.

B-F2 (kalender-flake): `pruneContentHistory` fikk valgfri `today = new Date()`-
param (deterministisk rotårsak-fix; CLI/hook-kall uendret via default). Prune-
testene injiserer fast syntetisk today og asserter kun på Recent Posts-seksjonen
(ikke helinnhold/frontmatter), så today-100d aldri kolliderer med SAMPLE_STATE-
datoer. Samme grep i `scripts/check-replace-safety.mjs`.

Suiter (alle grønne): test-runner 138/0 · hooks 140/0 (+1 regresjonstest) ·
trends 245/0 · brain 134/0 · tests 35/0 · render 20/0.

Utført av Fable 5 (high) subagent, orkestrert + verifisert av Opus-hovedkontekst.
