Expose workspace tools in sandbox mode

[chubes4]

Summary

• Register Data Machine Code workspace tools for sandbox mode in addition to chat and pipeline.
• Keep write/edit/git tools marked as explicit opt-in tools.
• Add a datamachine_code_remote_workspace_backend_should_handle filter so sandbox hosts can force the mounted local workspace backend even when git is unavailable.
• Update the workspace policy smoke test to cover sandbox mode exposure.

Tests

• php tests/smoke-workspace-policy-tools.php
• php tests/smoke-remote-workspace-backend.php
• homeboy lint --path /Users/chubes/Developer/data-machine-code@fix-workspace-tools-sandbox-mode --extension wordpress --changed-since origin/main --errors-only

Fixes chubes4/wp-codebox#175

AI assistance

• AI assistance: Yes
• Tool(s): OpenCode (GPT-5.5)
• Used for: Traced WP Codebox sandbox failures to missing Data Machine Code tool mode registration and backend routing, drafted the minimal mode/filter updates and smoke-test coverage, and ran focused verification.
