What's New
Major version jump from rust-v0.0.56 to v1.12.6 with security backports and bug fixes

- WebhookTest.json fixture made hermetic
Bug Fixes
- MCP flow input schemas derived without running stored component code
- Type Convert JSON and Message outputs accept dictionary inputs
- Numeric columns handled in Replace Value operation
- Bundle release reuse rejected
Upgrade Notes
This represents a significant version jump. Ensure flows using Type Convert JSON or Message are updated to handle dictionary inputs. MCP schemas are now derived without executing component code, which may affect flows relying on schema introspection.
