Subject: [PATCH] refactor(platform/mod): selective re-exports replace 8 star
 re-exports (ADR-025 L3)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

platform/mod.nu had 8 `export use X *`. Each is now explicit symbol list.

Symbol counts per target:
  target.nu           12
  discovery.nu         5
  health.nu            4
  credentials.nu       6
  connection.nu        9
  cli.nu               7
  autostart.nu         7
  service-manager.nu  15

Total: 65 symbols re-exported.

Pre-existing duplicate symbols surfaced by the explicit listing (not caused
by this commit — the `export use X *` pattern silently shadowed them):
  - get-service-status: connection.nu (arg) + autostart.nu (no arg)
  - start-required-services: service-manager.nu + autostart.nu
  - load-deployment-mode: target.nu + service-manager.nu

Leaving duplicates as-is; resolving the naming collisions is out of scope
for ADR-025 (tracked as pre-existing bug to address in a separate commit).

Validation:
  nu --ide-check 50 platform/mod.nu -> 0 errors
