fix(models): correct --all flag logic to build both models

Fix bug where --all flag only built CodeT5, not MiniLM.

Issue: The BUILD_MINILM condition excluded --all from the logic:
  BUILD_MINILM = args.includes('--minilm') || (\!args.includes('--codet5') && \!args.includes('--all'))

When --all was passed, this evaluated to false because:
  false || (true && false) = false

Fix: Explicitly include --all in both conditions:
  BUILD_MINILM = args.includes('--all') || args.includes('--minilm') || \!args.includes('--codet5')
  BUILD_CODET5 = args.includes('--all') || args.includes('--codet5')

Now the behavior is correct:
- No flags: MiniLM only (default)
- --minilm: MiniLM only
- --codet5: CodeT5 only
- --all: Both MiniLM and CodeT5
