fix(ci): remove deno test step; re-trigger CFL with updated workflow

deno test -A was failing with "No test modules found" — after excluding
_attic/ from deno.json test config, no Deno test files remain. This
Rust/ReScript project has no Deno tests; removing the step is correct.

Extend cflite_pr.yml paths filter to also fire on .clusterfuzzlite/**
changes (not just *.rs), so future build.sh / project.yaml edits re-run
the fuzzer CI without needing a dummy .rs touch.

Add SPDX header to fuzz_main.rs (a .rs change) to force this commit to
trigger a fresh CFL run, picking up the corrected cflite_pr.yml that
drops the undefined sanitizer matrix entry and guards upload-sarif with
hashFiles().
