Support `continue-on-error` for workflow jobs when aggregating an
Actions workflow run status.
Previously, `continue-on-error` was parsed from workflow YAML but was
not persisted or used when calculating the overall run result. As a
result, a failed job could incorrectly fail the entire workflow even
when the workflow explicitly allowed that job to fail.
This PR stores the parsed `continue-on-error` value on each action run
job and treats failed jobs with `continue-on-error: true` as successful
when computing the workflow run status, matching GitHub Actions
behavior.
## Changes
- Add `ContinueOnError` to `jobparser.Job`.
- Add `continue_on_error` to `ActionRunJob` with a `NOT NULL DEFAULT
FALSE` migration.
- Populate `ActionRunJob.ContinueOnError` when creating workflow run
jobs.
- Update workflow status aggregation so failed `continue-on-error` jobs
do not fail the overall run.
- Leave `resolveCheckNeeds` unchanged so dependent jobs still see the
job result as `failure` and are skipped by default.
## Compatibility
This is backward compatible.
If only the runner or only the server is updated, `continue-on-error`
continues to degrade to the previous behavior and is effectively ignored
until both sides support it.
