tests: replace host-env barrel imports with canonical host-env split modules

[Copilot]

Several unit tests still imported symbols from src/host-env.ts (backward-compat barrel) instead of the post-split canonical modules, which kept dead re-exports artificially alive and blurred module boundaries.
This PR updates those tests to import from the focused modules (host-identity, github-env, constants) while keeping host-env imports only for symbols still owned there.

• Import path realignment

  • src/docker-manager-utils.test.ts
    • moved identity symbols to ./host-identity
    • moved GitHub env parsing/path symbols to ./github-env
    • kept testHelpers and stripScheme in ./host-env
  • src/docker-manager-lifecycle.test.ts
    • moved AGENT_CONTAINER_NAME import to ./constants
  • src/compose-generator.test.ts
    • moved ACT_PRESET_BASE_IMAGE import to ./host-identity

• Mock consistency for split modules

  • src/config-writer.test.ts
    • switched getRealUserHome test import to ./host-identity
    • wired ./host-env and ./host-identity mocks to the same mockGetRealUserHome function so behavior remains aligned with existing test expectations

• Representative change

  // before
  import { AGENT_CONTAINER_NAME } from './host-env';
  
  // after
  import { AGENT_CONTAINER_NAME } from './constants';

Pull request overview

This PR updates unit tests to stop importing host environment helpers via the src/host-env.ts backwards-compat barrel when canonical split modules exist, helping keep module boundaries clear and preventing dead re-exports from being kept alive by tests.

Changes:

• Replaced ./host-env barrel imports in tests with direct imports from ./host-identity, ./github-env, and ./constants where appropriate.
• Kept ./host-env imports only for symbols that still live there (testHelpers, stripScheme).
• Adjusted config-writer.test.ts mocks so getRealUserHome behavior stays aligned across host-env and host-identity.

File	Description
src/docker-manager-utils.test.ts	Splits a large host-env barrel import into focused host-identity + github-env imports, keeping only remaining host-env symbols.
src/docker-manager-lifecycle.test.ts	Switches AGENT_CONTAINER_NAME import to the canonical constants module.
src/config-writer.test.ts	Updates getRealUserHome import to host-identity and aligns mocks between host-env and host-identity.
src/compose-generator.test.ts	Switches ACT_PRESET_BASE_IMAGE import to the canonical host-identity module.

Addressed in 78e8dc6. I updated Security Guard’s relevance filter to ignore test-only file paths (tests/ and *.test.*) before matching security-critical patterns, so this PR should skip the Security Guard agent job instead of failing on a non-security test-only diff.
