[plan] Add missing MCP properties to main workflow schema

[github-actions]

Objective

Add 4 missing MCP properties to main_workflow_schema.json that are already implemented in the codebase but not validated by the schema.

Context

From discussion #11706: The main schema is missing registry, allowed, entrypoint, and mounts properties that are already implemented in pkg/parser/mcp.go, pkg/workflow/mcp-config-custom.go, and tested in mcp_config_compilation_test.go. This causes users to not discover these fields via schema validation.

Approach

Update pkg/parser/schemas/main_workflow_schema.json (lines 3398-3477) in the tools.additionalProperties section to include:

1. registry (string) - URI to installation location from MCP registry
2. allowed (array of strings) - List of allowed tool names
3. entrypoint (string) - Container entrypoint override
4. mounts (array) - Volume mounts with pattern ^[^:]+:[^:]+:(ro|rw)$

Files to Modify

• pkg/parser/schemas/main_workflow_schema.json - Add 4 missing properties to tools.additionalProperties

Acceptance Criteria

• registry property added with type string and description
• allowed property added as array of strings
• entrypoint property added with type string
• mounts property added as array with pattern validation
• All properties include examples matching existing documentation
• Schema remains valid JSON
• Run make build to embed updated schema
