Conversation
Replace the state->repeat checks that guard mark saving and restoring with an explicit save_marks counter maintained where repeat and possessive contexts are entered and left. Each push is now paired with a pop decided by the same condition. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Replace the state->repeat checks that guard mark saving and restoring with an explicit save_marks counter maintained where repeat and possessive contexts are entered and left. Each push is now paired with a pop decided by the same condition. As a side effect, POSSESSIVE_REPEAT no longer allocates the placeholder repeat context introduced in gh-101955.
Extracted from #152027, which needs mark saving outside of any repeat context and will be rebased on top of this.
