Tom Boucher da368311ea feat(#1680): ADR-1239 Phase C-1 — imperative embedding adapter (composes loadRegistry) [AC2] (#1803)
* feat(#1680): ADR-1239 Phase C-1 — imperative embedding adapter (composes loadRegistry) [AC2]

Phase 3 slice 2 (AC2). The engine-as-library path: createImperativeAdapter
composes loadRegistry({includeInstalled:true}) — first-party-wins + consent +
fail-closed gates, identical trust semantics to the CLI — and binds the engine
surface behind the SAME HostIntegrationInterface the declarative adapter (AC1)
satisfies, plus a registry accessor for the composed capability set.

- src/adapter-imperative.cts: createImperativeAdapter({runtime}, {loadOptions})
  → ImperativeAdapter (kind:'imperative' + .registry + install/uninstall
  delegating to install-engine). Thin: delegates the loop, does not reimplement.
- tests/adapter-imperative.test.cjs: kind (16 runtimes), registry composition
  (loadRegistry called with includeInstalled:true), loadOptions pass-through,
  install/uninstall delegation, fail-closed construction.
- eslint.config.mjs + docs/INVENTORY-MANIFEST.json: ADR-457 ignores entry +
  cli_modules entry for the new emitted .cjs (the two drift gates that bit AC1,
  applied proactively here).

Concrete host binding (OpenCode/VS Code/pi) deferred to Phase 5 (#1682).

* test: remove dead readStateMd helper from bug-1760 test

readStateMd was defined but never called (writeStateMd is the only state-md
helper this test uses). Clears the lone no-unused-vars warning so the repo
lints fully clean (0 problems). No behavior change — test still passes 2/2.

* chore(changeset): add Changed fragment for imperative embedding adapter (#1680)

* fix(adapter-imperative): reword comment to avoid injection-scan substring match

The prompt-injection scan regex 'act\s+as\s+(?:a|an|the)' was matching the
'act as the' substring inside 'contract as the declarative adapter' (contrACT
AS THE). Reword 'contract as' -> 'shape as' — no 'act' substring, identical
meaning. Clears the 'lib source files are clean' + 'codebase prompt injection
scan' security-gate failures.

Changed 1803

Internal: the imperative embedding adapter now composes the capability registry behind the same HostIntegrationInterface — createImperativeAdapter({runtime}) (new src/adapter-imperative.cts) calls loadRegistry({includeInstalled:true}) (first-party-wins + consent + fail-closed — identical trust semantics to the CLI) and binds the engine surface behind the same contract the declarative adapter (AC1) satisfies, plus a registry accessor for an in-process host to bind its primitives to (ADR-1239 Phase C-1 / #1680 AC2). Concrete host binding is deferred to Phase 5. No user-facing change — the adapter is not yet wired to any runtime path.
