The repack step in build-wheels.mjs was producing wheels where copilot/bin/copilot had 0o644 (-rw-r--r--) permissions because setuptools strips the executable bit when building package data. After extracting the wheel for repack, restore chmod 0o755 on the CLI binary so that zf.write() captures the correct permissions. This ensures pip/uv install the binary as executable on Unix.

Pull request overview
Fixes the Python SDK wheel repackaging step so the bundled Copilot CLI binary is installed with correct Unix executable permissions, avoiding post-install manual chmod.
Changes:
- During wheel repack, re-apply
0o755to the extractedcopilot/bin/copilot(andcopilot.exe) before re-zipping so the wheel captures executable mode bits correctly. - Add the necessary import to support the new permission-restoration logic in the embedded repack script.

Problem
When installing the Python SDK via pip/uv, the bundled CLI binary at copilot/bin/copilot is installed without the Unix executable bit, requiring users to manually chmod it.
Root Cause
setuptools strips the executable bit when packaging data files. The repack step in build-wheels.mjs then captures this 0o644 permission into the wheel ZIP.
Fix
After extracting the wheel for repack, restore chmod 0o755 on the CLI binary so zf.write() captures the correct permissions.
