feat(parser): Phase 285A1.4 & A1.5 - Weak field sugar + Parser hang fix

A1.4: Add sugar syntax `public weak parent` ≡ `public { weak parent }`
A1.5: Fix parser hang on unsupported `param: Type` syntax

Key changes:
- A1.4: Extend visibility parser to handle weak modifier (fields.rs)
- A1.5: Shared helper `parse_param_name_list()` with progress-zero detection
- A1.5: Fix 6 vulnerable parameter parsing loops (methods, constructors, functions)
- Tests: Sugar syntax (OK/NG), parser hang (timeout-based)
- Docs: lifecycle.md, EBNF.md, phase-285a1-boxification.md

Additional changes:
- weak() builtin implementation (handlers/weak.rs)
- Leak tracking improvements (leak_tracker.rs)
- Documentation updates (lifecycle, types, memory-finalization, etc.)

feat(weak): Phase 285A1 - Weak Field Contract (Strict Type Enforcement)

Remove automatic WeakNew conversion and enforce strict compile-time type
checking for weak field assignments. Only 3 assignment types allowed:
1. Result of weak(x) call (WeakRef type)
2. Existing WeakRef variable (e.g., me.parent = other.parent)
3. Void/null (clear operation)

**Implementation**:
- Added MirType::WeakRef to type system (src/mir/types.rs)
- Track WeakRef type in emit_weak_new() even in pure mode
- Weak field reads return WeakRef without auto-upgrade
- Removed automatic WeakNew conversion from field writes
- Implemented check_weak_field_assignment() with actionable errors
- Fixed null literal type tracking (Phase 285A1.1: Unknown → Void)

**Testing**:
- 5 test fixtures (3 OK, 2 NG cases) - all passing
- Smoke test: phase285_weak_field_vm.sh
- Error messages guide users to use weak() or null

**Documentation**:
- Updated lifecycle.md SSOT with weak field contract
