Create GitHub pull request(s) from the current branch. If this session touched multiple repos (check conversation context, plan issue, or ask the user), create a PR in each repo. Run steps 1-8 for each repo in sequence. 1. **Check state**: Run `git status` and `git branch --show-current`. 2. **Prepare a branch**: - Always fetch the latest base branch (main/master) first. - If the current branch is main/master, create a new branch off the freshly fetched base. Pick a short, descriptive branch name from the conversation context (e.g. `resource-tags-docs`). Move any uncommitted changes to the new branch. - Otherwise, rebase the current branch onto the freshly fetched base. If there are conflicts, stop and ask the user to resolve them. 3. **Handle uncommitted changes**: If there are uncommitted changes on the (now non-master) branch, ask the user if they want to commit first. Do not proceed until the working tree is clean. 4. **Push the branch**: Push the current branch to remote with `git push -u origin`. 5. **Gather context**: Read the git log for all commits on this branch since it diverged from the base branch. If a plan issue was referenced in this conversation, read it for additional context. Check for a PR template at `.github/pull_request_template.md` or `.github/PULL_REQUEST_TEMPLATE.md` in the repo. If one exists, use it as the structure for the PR description. 6. **Create the PR**: Use `gh pr create` with `--title`, `--body`, and `--web` (opens the browser wi
