refactor(coding-agent): restructured tool rendering to merge call and result displays

- Changed tool result rendering to merge call and result displays with tool arguments in headers across 13 tools.
- Added args parameter to render methods enabling display of contextual metadata like patterns, paths, and commands.
- Changed Read tool title to display line range when offset or limit arguments provided.
- Changed worker instantiation to use direct URL import instead of pre-bundled worker files.
- Removed streaming preview rendering logic from write tool.
