Second PR in single chat session silently dropped (mobile)

Description

When asking Claude Code to create two PRs sequentially in a single chat session (web/mobile), the second PR's code gets committed and pushed to the branch, but the PR itself is never created on GitHub. No error is shown to the user.

Steps to Reproduce

1. Start a Claude Code session (web or mobile)
2. Ask Claude to implement a change and create PR #1 → succeeds
3. In the same chat, ask for a second change and PR #2
4. Code is committed and pushed, but the PR is never opened

Evidence

• Repo: BarakEm/shadow_master
• Branch: claude/mobile-friendly-web-app-hkP70
• PR #166 (first request) → created and merged successfully
• Commit 49928b1 (second request) → pushed to branch but no PR created
• Had to recover manually in a new session → PR #167

Impact

Work is silently lost from the user's perspective. The commit exists on the remote branch but no PR is opened, and there is no error or indication that anything went wrong.

Workaround

Use a separate chat session for each PR.
