feat(phase285w): Implement weak x unary operator syntax
Phase 285W-Syntax-0: Migrate weak reference syntax from function call
to unary operator for consistency and clarity.
**Changes**:
- Parser: Add UnaryOperator::Weak variant and parse_unary() handling
- MIR: Lower UnaryOp::Weak to emit_weak_new() (reuses existing path)
- AST: Add Weak to UnaryOperator enum + Display/JSON support
- Tests: Migrate 8 files from `weak(x)` to `weak x` syntax
- 7 .hako test files updated
- 1 smoke test shell script updated
- Cleanup: Remove obsolete weak(x) parser/MIR special cases
- Docs: Update Phase 285 README
**Syntax Change**:
- Old: `local w = weak(x)` (function call)
- New: `local w = weak x` (unary operator)
**Validation**: All migrated phase285* smoke tests pass (4/4 relevant)
**SSOT**: docs/reference/language/lifecycle.md
