Avoid allocations in `ForkMap::contains` (#20023) ## Summary `ForkMap::contains` currently calls `get`, which collects every matching value into a temporary vector only to test whether that vector is empty. This checks the underlying entries with `any` instead, avoiding the allocation and stopping at the first matching scope. The existing `ForkMap` test covers both matching and excluded scopes. This was identified while reducing resolver overhead in #19993, but applies independently to existing `ForkMap` users.

Split slow group `run_groups_requires_python` test (#20012) `run_groups_requires_python` performs a long sequence of interpreter selection, virtual environment replacement, reuse, downgrade, and error checks in one test. The repeated `uv run` invocations make it substantially slower than nearby tests and cause frequent slow timeouts. This splits the scenario into focused tests for automatic interpreter selection, environment reuse and explicit downgrade, and error reporting. Each test uses only Python 3.12 and 3.13, empty dependency groups, and `python --version`, preserving the group `requires-python` behavior without unrelated registry resolution or package installation.

Add jitter to Docker release builds (#20021) ## Summary - add a random 0–10 second delay before versioned Docker release builds enter the release environment gate - leave pull request dry-runs and `uv-dev` builds unchanged This staggers the extra-image matrix jobs and reduces the chance of race conditions in the release environment gate. ## Test plan - `uvx prek run prettier --files .github/workflows/build-docker.yml` - `uvx zizmor .github/workflows/build-docker.yml` - `git diff --check`
