Tom Boucher 1fa7bc594c refactor(#1190): extract ADR-230 PR-target branch policy into a tested, fork-safe seam (#1246) ...

ADR-230's branching-model gate (pr-target-validator.yml) decided allowed/blocked PR targets via inline regex in github-script — untestable. Extracted the decision into committed scripts/pr-target-policy.cjs (classifyPrTarget(base,head)->{decision}), and rewired the workflow to checkout the BASE ref (trusted; fork-tamper-safe) + require the module. Behavior-identical (Codex-verified char-by-char regex equivalence + all side-effects preserved). 70 tests incl. an equivalence oracle battery + hyphen-boundary negatives. Added contents:read for the checkout. Re-attribution: no ADR-230 test references exist (issue's '2 misattributed files' claim not borne out).

Closes #1190
