Fix critical issues in MCP release workflow

Address all critical review comments:

1. Fix malformed Docker tags
   - Change tag suffixes from colons to hyphens
   - standalone: 1.0.0-standalone (not 1.0.0:standalone)
   - combined: 1.0.0 and latest (not :latest)

2. Add checkout ref for manual triggers
   - Use inputs.tag for workflow_dispatch events
   - Ensures manual builds use correct tag ref

3. Add tag input validation
   - Validate tag format (mcp-vX.Y.Z) before processing
   - Provide clear error messages for invalid input

4. Fix release summary overwriting
   - Both matrix jobs now append to summary correctly
   - Each variant creates distinct summary section
