fix(lazy-load): exclude function_manifest.sh from the early find-loop

The early loop in sourceInitilize() sources every .sh under source/files/
recursively — including the new arrays/function_manifest.sh, which now
carries ~860 autoload stub definitions (~50 ms parse cost). Even in
eager mode where lazy infrastructure is never touched, every invocation
was paying that cost up front.

The manifest is only needed in lazy mode, where it's sourced explicitly
at the top of the lazy branch. Excluding it from the early loop:
  - Eager mode: drops the ~50 ms regression introduced by Phase 5.
  - Lazy mode: unchanged — the explicit source still runs.

This brings eager back to the pre-Phase-5 baseline and lets the lazy
container-stub gain (skipping sourceScanFiles containers, ~70 ms) show
through as a real saving.
