fix: Silence chmod failures on read-only folders

[Copilot]

The action runs chmod -R +rw on deployment folders to enable rsync operations. When folders are read-only (e.g., root-owned), these commands fail and flood the output with permission errors, even though the deployment succeeds.

Changes

• src/git.ts: Made both chmod commands run silently (silent: true) and wrapped in try-catch blocks without error messages
• __tests__/git.test.ts: Added test verifying deployment succeeds despite chmod failures

The chmod operations are non-critical optimizations—rsync can proceed without them in most cases. This change prevents output pollution while maintaining functionality.

// Before: floods output with permission errors
try {
  await execute(`chmod -R +rw ${action.folderPath}`, action.workspace, action.silent)
} catch {
  info(`Unable to modify permissions…`)
}

// After: fails silently
try {
  await execute(`chmod -R +rw ${action.folderPath}`, action.workspace, true)
} catch {
  // Silently ignore - non-critical optimization
}

<issue_title>bug: 🐝 Unable to modify permissions…</issue_title>
<issue_description>### Describe the bug

The folder I'm deploying is read-only, and permissions can't be changed. I don't know why it is important to modify the permissions in the first place, while I see a lot of warnings/errors, it seems to work just fine. It would be nice if those messages wouldn't be flooding the output.

Reproduction Steps

Use a folder that is read only and owned by root.

<agent_instructions>It has been necessary to modify permissions before now in times where the runner doesn't have access. It should fail this step silently I think. </agent_instructions>
