feat(devtools): add release command and trigger PyPI publish

* feat(devtools): add release command and fix automerge on protected branches

Replace gh pr merge --auto with polling-based merge wait that prints the
PR URL for manual review. Add unified release command that chains bump
and tag into a single end-to-end workflow.

* feat(devtools): trigger PyPI publish workflow after GitHub release

* refactor(devtools): extract shared helpers to eliminate duplication

Extract _poll_pr_until_merged, _update_all_versions,
_generate_release_notes, _update_docs_and_create_pr,
_create_tag_and_release, and _trigger_pypi_publish into reusable
helpers. All three commands (bump, tag, release) now compose from
these shared functions.

+# crewai-devtools
+
+CLI for versioning and releasing crewAI packages.
+
+## Setup
+
+Installed automatically via the workspace (`uv sync`). Requires:
+
+- [GitHub CLI](https://cli.github.com/) (`gh`) — authenticated
+- `OPENAI_API_KEY` env var — for release note generation and translation
+
+## Commands
+
+### `devtools release <version>`
+
+Full end-to-end release. Bumps versions, creates PRs, tags, and publishes a GitHub release.
+
+```
+devtools release 1.10.3
+devtools release 1.10.3a1      # pre-release
+devtools release 1.10.3 --no-edit   # skip editing release notes
+devtools release 1.10.3 --dry-run   # preview without changes
+```
+
+**Flow:**
+
+1. Bumps `__version__` and dependency pins across all `lib/` packages
+2. Runs `uv sync`
+3. Creates version bump PR against main, polls until merged
+4. Generates release notes (OpenAI) from commits since last release
+5. Updates changelogs (en, pt-BR, ko) and docs version switcher
+6. Creates docs PR against main, polls until merged
+7. Tags main and creates GitHub release
+
+### `devtools bump <version>`
+
+Bump versions only (phase 1 of `release`).
+
+```
+devtools bump 1.10.3
+devtools bump 1.10.3 --no-push      # don't push or create PR
+devtools bump 1.10.3 --no-commit    # only update files
+devtools bump 1.10.3 --dry-run
+```
+
+### `devtools tag`
+
+Tag and release only (phase 2 of `release`). Run after the bump PR is merged.
+
+```
+devtools tag
+devtools tag --no-edit
+devtools tag --dry-run
+```
