* ci: move secondary, scheduled and contract workflows to GitHub-hosted runners
Public-repo standard hosted runners are free under Enterprise. Release, build,
benchmark, e2e and unit workflows stay on Blacksmith. ci-xterm-cache seeds both
cache stores since its PR consumer's pool is undecided.
* test(pi): resolve the smoke bundle's external packages from the repo
#34148 pulled zod into the commit-message planner graph; the bundle in the
OS temp dir could not resolve it on any runner.
* ci(unit): use four workers on the hosted four-core x64 runner

Extract subprocess execution and process contracts into @orca/process-host with explicit public entry points, independent checks, and one Node 18 compatible CommonJS runtime. Migrate application consumers and integrate package builds, dependency selection, import enforcement, and runtime resource staging.
Preserve daemon startup ownership and profile isolation, and qualify development rebuild recovery and concurrent output publication. Remove unnecessary aliases, test forwarding exports, and a duplicate output scan.
Validation: full typechecks, changed-code quality, package and artifact checks, native Windows builds/types plus 306 runtime tests, and independent native reviews.
Matched full E2E controls on original main and unchanged reviewed head both pass all 17 applicable tests (nine skips). Earlier intermittent E2E failures are documented in the PR; no assertions were weakened. The final combined-tree audit preserves both branches with no import-boundary violations.
