chore(build): update @playform/build dependency

Updates Playform Build toolchain to v0.2.4 to leverage latest bundling improvements for the Cocoon extension host environment. This aligns with Land's strategy to maintain modern build tooling for:
- Enhanced JS/TS compilation of Shim layer code
- Improved tree-shaking in Rest's extension host bundle generation
- Better sourcemap handling for debugging extension host interactions

Ensures compatibility with latest TypeScript features used in VS Code extension shim development while maintaining stability in the MVP Path A architecture.
