fix(GREEN): semantic match guard kills follow hallucination at 3 layers

Implements the _intent_matches_node() guard — a shared SSOT function that
validates clicked elements against intent keywords before trusting any
verification result.

Fixes applied:
1. action_memory.py: verify_success() now cross-checks clicked element
   against intent BEFORE trusting structural delta for toggle actions
2. action_memory.py: confirm_click() blocks Qdrant poisoning when the
   tracked click doesn't semantically match the intent
3. q_nav_graph.py: 'follow' added to action_checks map (screen-sanity)
4. goap.py: Pre-click semantic guard prevents device.click() on elements
   that don't match toggle intents (follow/like/save)

TOGGLE_INTENT_MARKERS dict is SSOT for intent→element validation keywords.
Supports DE locale (gefolgt, abonnieren, gefällt, speichern).

162 passed, 0 regressions. All 5 previously-RED tests now GREEN.
