Narrow the test-deploy-{server,universal,workstation} matrix to roles
actually impacted by the branch's diff against origin/main, expanded
transitively over run_after + dependencies + shared services.
Why: full-matrix deploy CI on every PR is wasteful; explicit per-PR
whitelisting is error-prone. The resolver derives the affected set
automatically while remaining fail-safe.
Behaviour (in resolve_effective_whitelist.sh precedence order):
- whitelist input "__ALL__" -> empty whitelist (force full deploy)
- whitelist input non-empty -> verbatim
- whitelist input empty -> diff vs origin/main
- empty diff or any path outside roles/<role>/ -> __ALL__
- all paths under roles/<role>/ -> reverse closure
Fail-safe: any seed that is not modellable in CombinedResolver
(no application_id and not referenced by any role's run_after) and
any resolver runtime error MUST trigger a fall-back to __ALL__.
The closure never silently shrinks the deploy matrix.
test-deploy-local.yml is intentionally exempt (local/manual dispatch
keeps explicit whitelist semantics).
