Fix DocC workflow: use xcrun docc convert

[SoundBlaster]

Summary

Fixed the failing DocC workflow by replacing the incorrect swift package generate-documentation command with xcrun docc convert.

Problem

The workflow was failing with:

error: Unknown subcommand or plugin name 'generate-documentation'

The swift package generate-documentation command requires the Swift-DocC plugin to be added to Package.swift, which is not available by default.

Solution

Changed the Build Documentation step to use xcrun docc convert directly:

- name: Build Documentation
  run: |
    xcrun docc convert mcpbridge-wrapper.docc \
      --output-path ./docs \
      --transform-for-static-hosting \
      --hosting-base-path mcpbridge-wrapper

This is the standard approach for converting DocC documentation catalogs.

Changes

• .github/workflows/docs.yml: Replaced swift package generate-documentation with xcrun docc convert

Testing

• Workflow will be tested after merge
• Documentation should build successfully
• GitHub Pages should deploy correctly
