// ─── _applyRuntimeRewrites(cursor) — bare-form regression (#1356) ────────────
//
// Prior to this fix the cursor branch only rewrote trailing-slash ~/.claude/
// and $HOME/.claude/ forms.  Bare end-of-token references (end of line,
// inside backtick spans, before punctuation) survived and triggered the
// post-install audit "Found N unreplaced .claude path reference(s)".
//
// Fix: add three bare-form rewrites (mirroring augment/windsurf/trae) using
// (?![\w-]) to avoid corrupting .claude-plugin / .claudeignore.
//
// TDD proof: these assertions FAIL before the fix and PASS after.
