v2-ci / unit-tests (push) Waiting to run
feat(scripting): out-of-process pre-emptible script runner behind Scripting:Runner (lmxopcua#780 P1)
Opt-in (Scripting:Runner=OutOfProcess; InProcess stays the default and its code path is unchanged). Implements
the P1 slice of docs/plans/2026-11-09-out-of-process-script-runner-design.md with the owner's §14 decisions:

- Options: Scripting:Runner (InProcess | Shadow | OutOfProcess), Scripting:Runner:Seams, Scripting:Worker:*
  (Shards 2, HardGrace max(1 s,T), HeapLimitBytes 512 MiB, QuarantineAfterKills 2, UnavailableGrace 5 s,
  IsolationProbationRuns 20, PeCacheDir validated absolute + outside the content root (fail closed),
  ExecutablePath). Shadow is not implemented yet: runs InProcess with a startup Warning.
- Core.Scripting: IScriptRunner seam + InProcessScriptRunner (today's guard, the parity baseline).
- Core.Scripting.Protocol: protobuf envelopes, 4-byte LE framing (zero/oversize/truncated/garbage refused),
  Variant carrying the exact CLR type; unsupported types are explicit failures.
- ScriptWorker app: compiles in the worker, P-thread scheduler, host-driven soft cancel, fail-fast
  watchdog, heartbeats, ctx.Logger forwarding, exits on pipe EOF / parent gone, forbidden-assembly
  self-check; Akka and Grpc.Core.Api excluded from its folder. Shipped in script-worker/ (Build + Publish).
- Core.Scripting.OutOfProcess: K shards + isolation worker, soft T / hard T+G kill, attribution
  (deadline kill = one key; crash = suspects -> isolation; isolation crash = strike), kill-strike
  quarantine, backoff 250 ms -> 30 s, fail closed, cleared allow-listed env, nonce + pid handshake on a
  current-user pipe, Windows Job Object.
- VirtualTag + Calculation seams use the runner when selected; a runner-side failure (worker restarted /
  runner unavailable) publishes BadResourceUnavailable (0x80040000) — ScadaBridge#112. Script faults keep
  BadInternalError. The scripted-alarm seam stays in process (alarms last).

Tests: new ZB.MOM.WW.OtOpcUa.ScriptWorker.Tests (Category=ScriptWorker, real processes; green on macOS and
on windev/Windows), seam tests in Host/Runtime/Calculation suites; mutation-checked.
