Consolidate four separate PR labeling workflows (`pr_labeler_file.yml`, `pr_labeler_title.yml`, `pr_size_labeler.yml`, and the PR-handling half of `tag-external-contributions.yml`) into a single `pr_labeler.yml` workflow. The old workflows raced against each other — concurrent label mutations could drop or duplicate labels depending on execution order. A unified workflow with concurrency grouping eliminates that class of bug.

# PR title linting.
|
||
#
|
||
# FORMAT (Conventional Commits 1.0.0):
|
||
#
|
||
# <type>[optional scope]: <description>
|
||
# [optional body]
|
||
# [optional footer(s)]
|
||
#
|
||
# Examples:
|
||
# feat(core): add multi‐tenant support
|
||
# fix(langchain): resolve error
|
||
# docs: update API usage examples
|
||
# docs(openai): update API usage examples
|
||
#
|
||
# Allowed Types:
|
||
# * feat — a new feature (MINOR)
|
||
# * fix — a bug fix (PATCH)
|
||
# * docs — documentation only changes
|
||
# * style — formatting, linting, etc.; no code change or typing refactors
|
||
# * refactor — code change that neither fixes a bug nor adds a feature
|
||
# * perf — code change that improves performance
|
||
# * test — adding tests or correcting existing
|
||
# * build — changes that affect the build system/external dependencies
|
||
# * ci — continuous integration/configuration changes
|
||
# * chore — other changes that don't modify source or test files
|
||
# * revert — reverts a previous commit
|
||
# * release — prepare a new release
|
||
# * hotfix — urgent fix
|
||
#
|
||
# Allowed Scope(s) (optional):
|
||
# core, langchain, langchain-classic, model-profiles,
|
||
# standard-tests, text-splitters, docs, anthropic, chroma, deepseek, exa,
|
||
# fireworks, groq, huggingface, mistralai, nomic, ollama, openai,
|
||
# perplexity, qdrant, xai, infra, deps
|
||
#
|
||
# Multiple scopes can be used by separating them with a comma. For example:
|
||
#
|
||
# feat(core,langchain): add multi‐tenant support to core and langchain
|
||
#
|
||
# Note: PRs touching the langchain package should use the 'langchain' scope. It is not
|
||
# acceptable to omit the scope for changes to the langchain package, despite it being
|
||
# the main package & name of the repo.
|
||
#
|
||
# Rules:
|
||
# 1. The 'Type' must start with a lowercase letter.
|
||
# 2. Breaking changes: append "!" after type/scope (e.g., feat!: drop x support)
|
||
# 3. When releasing (updating the pyproject.toml and uv.lock), the commit message
|
||
# should be: `release(scope): x.y.z` (e.g., `release(core): 1.2.0` with no
|
||
# body, footer, or preceeding/proceeding text).
|
||
#
|
||
# Enforces Conventional Commits format for pull request titles to maintain a clear and
|
||
# machine-readable change history.
