nyash-codex 192c29efb1 docs: Pattern 4 stub clarification (Phase 195 deferred)
Phase 33-11 Quick Wins - Task 2

Clarified that Pattern 4 (continue statements) is intentionally
not implemented, with explicit error message and migration guide.

Changes:
1. Added clear STUB IMPLEMENTATION header to module docs
2. Updated lower() to return explicit error (not silent stub)
3. Added #[doc(hidden)] and #[allow(dead_code)] annotations
4. Created comprehensive migration guide (phase-195-pattern4.md)

Status:
- Not implemented: Pattern 4 (continue)
- Use instead: Pattern 1-3 (simple/break/if+phi)
- Reason: Continue requires complex PHI analysis, lower priority
- Build:  Success (no errors, no new warnings)

Migration path:
- Pattern 1: Simple while loops (no break/continue)
- Pattern 2: Loops with break
- Pattern 3: Loops with if + PHI (workaround for continue)
- Pattern 4: (FUTURE) Loops with continue statements
