ci: scope workflow triggers to relevant paths

- codeflash-optimize.yaml: replace paths: ['**'] wildcard with targeted filters
- mypy.yml: add path filters (was firing on every PR/push including docs)
- prek.yaml: add path filters (was firing on every PR)
- unit-tests.yaml: add path filters (was firing on every PR/push)

Docs-only, README, experiment, and LICENSE changes no longer trigger
these workflows. Saves ~20 workflow runs per docs-only PR.
