feat(omo-native): add Wave 0 native adapter scaffold

[code-yeongyu]

Summary

Wave 0 for the omo-native plan: this adds the native adapter package boundary and Senpi submodule wiring without implementing the later runtime bridge. The new package builds to a Pi-compatible default-exported extension factory, while the focused native seam test intentionally stays RED for Wave 1's real Senpi/pi type-layer import.

This PR is intentionally draft-only. Do not mark ready and do not merge until explicitly requested.

Changes

• Adds packages/senpi as a git submodule pinned to 4ce93bcfbc7c681a709f2579f664b1bbf92fbc1b.
• Adds private workspace package @oh-my-opencode/omo-native with build.mjs, strict tsconfig, Pi manifest entry, and default-exported extension factory stub.
• Wires root build:native, root package typecheck coverage, and Bun test ignores for the new native/senpi trees.
• Keeps Wave 0 install independent from submodule internals, so CI checkout without submodules can still install/build/typecheck.
• Adds seam-boundary-audit.test.ts to block raw Senpi/pi imports outside src/senpi/**; its positive seam assertion is intentionally RED until Wave 1 replaces the local stub with a real Senpi/pi type-layer import.
• Updates script/package-registration-audit.test.ts so packages/omo-native is recognized as a managed native package/typecheck target without requiring a root workspace:* devDependency.
• Commits PR-facing QA evidence, including an actual rendered terminal/TUI screenshot.

Manual QA / Evidence

• bun install --frozen-lockfile --ignore-scripts: PASS, recorded in .omo/evidence/20260620-omo-native-wave-0/final-convention-fix-verification.txt.
• node packages/omo-native/build.mjs: PASS.
• bun run build:native: PASS, re-run after the package-registration CI fix in .omo/evidence/20260620-omo-native-wave-0/build-native-after-registration-fix.txt.
• node -e "import('./packages/omo-native/dist/index.js').then(m => console.log(typeof m.default))": PASS, printed function.
• bun run --cwd packages/omo-native typecheck: PASS, re-run after the package-registration CI fix in .omo/evidence/20260620-omo-native-wave-0/native-typecheck-after-registration-fix.txt.
• bun test script/package-registration-audit.test.ts: PASS after ac93763dd, 5 pass, 0 fail, recorded in .omo/evidence/20260620-omo-native-wave-0/package-registration-audit-fix-verification.txt.
• bun test: PASS after ac93763dd, 10072 pass, 2 skip, 0 fail, recorded in .omo/evidence/20260620-omo-native-wave-0/root-bun-test-after-package-registration-fix-summary.txt.
• bun run --cwd packages/omo-native test: expected RED; exit 1 is only the planned positive seam assertion requiring a real Senpi/pi type-layer import in Wave 1. The boundary audit itself passes.
• git diff --check and git diff --cached --check: PASS.
• tmux cleanup receipt: no ulw-qa-omo-native-wave0-terminal or omo-native QA session remains.

CI Status

Current head: ac93763dd (test(omo-native): register native package audit).

• GitHub CI is green on the current head after rerunning the previously cancelled Windows test.
• Passing current-head checks include build, Ubuntu/macOS/Windows typecheck, Ubuntu/macOS/Windows tests, Ubuntu/macOS/Windows Codex compatibility, CLA, labels, lazycodex published smoke, and GitGuardian.
• draft-release and auto-commit-schema are skipped by CI as draft/release-gated jobs, not failures.
• Cubic bot: no Cubic review/comment is present on this draft PR at the time of this update.

CI Fix Evidence

• First CI run failed during bun install because checkout does not initialize the new packages/senpi submodule and the initial lock/manifests linked file deps under packages/senpi/packages/*.
• Fix removes install-time Senpi internals from Wave 0 while preserving the pinned submodule.
• Pushed-branch repro: .omo/evidence/20260620-omo-native-wave-0/ci-nosubmodule-install-repro-pushed.txt cloned this branch at e59250899, removed packages/senpi, verified no install-time Senpi package links remain, then passed frozen install, native build, and native typecheck.
• Second CI run failed root bun test because the package registration audit did not yet classify packages/omo-native as managed.
• Fix commit ac93763dd adds nativePackagePaths to the audit and preserves the no-root-devDependency expectation for native packages. Local full-suite verification passed before push, and current-head GitHub CI is now green.

Known Intentional RED

The focused native test is not expected to go green in Wave 0. Its positive seam assertion is the guardrail that forces Wave 1 to replace src/senpi/types.ts with a real Senpi/pi type-layer import.

CI fix update after the first failed GitHub Actions run.

Root cause confirmed: GitHub Actions checkout does not initialize the new packages/senpi submodule, while the first Wave 0 scaffold made root bun install link file:packages/senpi/packages/{agent,ai}. That made every CI job fail during the install prerequisite with Failed to install 2 packages.

Fix pushed:

• e59250899 removes the install-time dependency on Senpi internals while keeping the submodule pinned for Wave 1.
• packages/omo-native still builds/typechecks from the local Wave 0 stub and still carries the intentional RED seam audit.

Fresh proof from the pushed branch:

• .omo/evidence/20260620-omo-native-wave-0/ci-nosubmodule-install-repro-pushed.txt
• Repro cloned code-yeongyu/omo-native-wave0 at e59250899, removed packages/senpi, confirmed no install-time Senpi package links remain, ran bun install --frozen-lockfile --ignore-scripts, node packages/omo-native/build.mjs, and bun run --cwd packages/omo-native typecheck successfully.

PR state remains draft-only, not ready, not merged.

CI fix update for Wave 0, keeping this PR draft-only.

What changed in ac93763dd:

• Reproduced the CI/root-suite failure: package-registration-audit.test.ts expected managed typecheck paths without packages/omo-native, while root typecheck:packages already included it.
• Updated the audit to classify packages/omo-native as a managed native package.
• Preserved the Wave 0 no-install-coupling rule by excluding native packages from the root workspace:* devDependency expectation.

Manual/local verification after the fix:

• bun test script/package-registration-audit.test.ts: PASS (5 pass, 0 fail).
• bun test: PASS (10072 pass, 2 skip, 0 fail).
• bun run build:native: PASS.
• bun run --cwd packages/omo-native typecheck: PASS.
• Cleanup: no ulw-qa-omo-native-wave0-terminal or omo-native tmux QA session remained.
