Prune dead host-env compatibility re-exports after module split

[Copilot]

After the host-env module split, src/host-env.ts still re-exported 18 symbols that no production code consumes through that barrel path. This PR removes those dead compatibility exports and aligns remaining test callers with canonical module import paths.

• API surface cleanup (src/host-env.ts)

  • Removed dead re-exports from:
    • ./constants (container names + env size constants)
    • ./host-identity (ACT_PRESET_BASE_IMAGE, MIN_REGULAR_UID, validateIdNotInSystemRange)
    • ./github-env (GitHub env/path parsing helpers + toolchain vars)
  • Kept active production-consumed exports (SQUID_PORT, host UID/GID/home helpers, etc.).

• Test import realignment (canonical ownership)

  • Updated tests that previously imported these symbols via ./host-env to import from their source modules:
    • src/docker-manager-utils.test.ts
    • src/docker-manager-lifecycle.test.ts
    • src/compose-generator.test.ts

• Representative change

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

Pull request overview

Cleans up the src/host-env.ts backward-compat barrel after the host-env module split by removing re-exports that are no longer consumed via that path, and updates tests to import those symbols from their canonical modules.

Changes:

• Removed dead compatibility re-exports from src/host-env.ts (constants, host-identity, github-env symbols).
• Updated tests to import the affected symbols from ./constants, ./host-identity, and ./github-env instead of ./host-env.
• Kept src/host-env.ts focused on the small set of production-consumed exports.

File	Description
src/host-env.ts	Removes unused barrel re-exports and narrows exported surface to production-consumed symbols.
src/docker-manager-utils.test.ts	Re-aligns imports to canonical modules (host-identity + github-env) while keeping host-env-only helpers.
src/docker-manager-lifecycle.test.ts	Switches AGENT_CONTAINER_NAME import to ./constants.
src/compose-generator.test.ts	Switches ACT_PRESET_BASE_IMAGE import to ./host-identity.
