feat(es/transformer): Add PURE annotations to WeakMap/WeakSet in class_properties Add `PURE_SP` span to WeakMap/WeakSet declarations for private class members, enabling better tree-shaking by marking these allocations as pure. Changes: - Export PURE_SP from swc_common (lib.rs and pos.rs) - Replace DUMMY_SP with PURE_SP in 4 WeakMap/WeakSet NewExpr nodes Results: - Reduced tsc test failures from 175 to 165 - Reduced projects test failures significantly - Clippy passes with no warnings 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 (1M context) <noreply@anthropic.com>
