chore: bump version to v0.1.3

[kaiitunnz]

Purpose

Release-prep bump for the v0.1.3 release. Drops the -rc.1 pre-release suffix and synchronizes all published package versions and first-party pins ahead of tagging and the PyPI publish.

Changes

• pyproject.toml, cli/pyproject.toml, cli/stack/pyproject.toml, hook/pyproject.toml, sdk/pyproject.toml, sdk/stack/pyproject.toml — bump version from 0.1.3rc1 to 0.1.3 and update internal first-party == pins to match.
• sdk/src/flowmesh/_version.py (_STATIC_VERSION) and src/shared/_version.py (FLOWMESH_RELEASE_VERSION) — bump the runtime version literals.
• uv.lock — re-locked for the new synchronized version.

All edits are the mechanical output of scripts/dev/bump_version.py 0.1.3 + uv lock.

Design

N/A — version bump only.

Test Plan

uv run scripts/dev/bump_version.py 0.1.3
uv lock
uv run scripts/ci/check_release_version.py --tag v0.1.3
uv build --all-packages --out-dir dist && uv run scripts/ci/check_package_build.py --dist dist
uv sync --all-packages --group ci --frozen
uv run pre-commit run --all-files
uv run pytest tests/ --ignore=tests/worker/test_mp_executor_cleanup_gpu.py

Test Result

$ uv run scripts/ci/check_release_version.py --tag v0.1.3   # synchronized at 0.1.3
$ uv build --all-packages && check_package_build            # 6 distributions built + smoke-tested, exit 0
$ uv run pre-commit run --all-files                         # isort / black / ruff / mypy / codespell / gitleaks / sync-requirements passed
$ uv run pytest tests/ --ignore=...gpu                      # 1071 passed

• I have verified that uv run pytest tests/ passes locally.
• If I changed shared schemas or proto definitions, I have checked downstream compatibility across Server and Worker. (No schema/proto changes.)
• If I changed the SDK or CLI, I have verified the affected packages work (uv sync --all-packages --group ci --frozen; built and smoke-tested all distributions).
• If this is a breaking change, I have prefixed the PR title with [BREAKING] and described migration steps above. (Not a breaking change.)
