Adds dynamic matrix evaluation to Gitea Actions: a job's
`strategy.matrix` can be built from the outputs of the jobs it needs.
```yaml
jobs:
generate:
runs-on: ubuntu-latest
outputs:
matrix: ${{ steps.set.outputs.result }}
steps:
- id: set
run: echo "result=[1,2,3]" >> $GITHUB_OUTPUT
build:
needs: [generate]
runs-on: ubuntu-latest
strategy:
matrix:
version: ${{ fromJson(needs.generate.outputs.matrix) }}
steps:
- run: echo "building ${{ matrix.version }}"
```
Such a matrix cannot be expanded at planning time, so the job is planned
as a single placeholder and expanded by the job emitter once its needs
finish. Each combination is then gated by `if:` and concurrency as
usual.
- A matrix that resolves to no combination fails the job, as on GitHub.
- Expansion is capped at `MaxJobNumPerRun`.
- Workflows without a needs-dependent matrix are unaffected.

Add support for `strategy.max-parallel` on Gitea Actions matrix jobs.
**How it works**
Jobs over the limit are inserted as `Blocked` instead of `Waiting`, so
runners never see them. When a job finishes, the job-status resolver
promotes one `Blocked` job per freed slot, in job order. Slots are
counted per `JobID` and scoped by reusable-workflow caller. A
`Cancelling` job still owns its runner, so it keeps its slot.
The cap is applied wherever a job can become `Waiting`: initial insert,
rerun, approval, and resolver promotion.
Best effort, not a hard invariant: two concurrent emitter passes can
each promote into the last slot, overshooting by one. It does not
compound, since every later pass recounts.
**Parsing**
Any YAML number, cast to an int as GitHub does (`1.5` → 1). `0` or
negative means unlimited. Expressions (`${{ ... }}`) are not evaluated
yet and fall back to unlimited.
**Migration**
Adds the `max_parallel` column on `action_run_job`. No index or
constraint changes.
**Compatibility**
Existing rows default to `0`, so behaviour is unchanged. No runner
changes needed: the runner protocol is untouched, and since the server
splits the matrix each runner still receives a single job.
