v0.4.0 - MCP Specification Compliance Fixes

This patch release focuses on MCP specification compliance and project improvements.

Bug Fixes

• Flattened Schema Handling (#93): Added automatic transformation of flattened schemas (string, number, boolean, array) to MCP-compatible object schemas. The MCP specification requires all tool input schemas to be of type "object" - abilities using flattened schemas now work correctly.

Improvements

• Tool Annotations Mapping (#91): Fixed annotation field name mismatches between WordPress Abilities API format and MCP specification. The adapter now correctly maps readonly → readOnlyHint, destructive → destructiveHint, and idempotent → idempotentHint for full protocol compliance.

• Added .gitattributes to exclude development files from releases (#94)

• Added GNU General Public License v2 (#97)

Documentation

• Fixed missing comma in transport permissions example (#85)

• Applied WordPress PHP documentation standards (#92)

• @BrianHenryIE made their first contribution in #94
• @jeffpaul made their first contribution in #97
