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 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

// Phase 285W-Syntax-0: WeakRef basic test with weak x syntax

// Test: weak x creates WeakRef, weak_to_strong() returns Box when alive
|
|
// Note: Full drop semantics test deferred (needs GC/scope analysis)
|
|
// VM: PASS expected
|
|
// LLVM: SKIP (Phase 285A1)
