Update @modelcontextprotocol/sdk to 1.25.2

Updates the MCP SDK from 1.25.1 to 1.25.2 and recreates the output
validation patch for the new version. The patch continues to convert
strict output schema validation errors to warnings, allowing tools
to gracefully handle schema mismatches.

Changes:
- Update @modelcontextprotocol/sdk from ^1.25.1 to ^1.25.2
- Recreate SDK patch for version 1.25.2
- Remove obsolete 1.25.1 patch file
- All 397 tests pass with new SDK version
