Summary

Add a new command available in the command palette to make sharing the current PR easier. The command should use a configurable message template stored in the app configuration, e.g.

share_pr_message = "Hey Team, could someone please review the PR [$PR_TITLE]($PR_URL)"

Variables like $PR_TITLE and $PR_URL must be replaced by the actual PR title and URL.

Implementation Details

• The message template comes from a new config field called share_pr_message (in TOML format).
• The command should be accessible via the command palette.
• When triggered, the command will:
  • Replace $PR_TITLE and $PR_URL in the template string with the active PR's title and URL
  • Offer two UX options (choose best):
    • Copy the result to the clipboard
    • Or, display the formatted message in the status bar so the user can manually copy it

Acceptance Criteria

• New config field implemented: share_pr_message
• Command added to command palette: "Share this PR"
• PR title/URL variables replaced in message
• Result copied to clipboard OR shown in status bar for copy
• Documentation updated for new feature
