fix(ci): copy Lua headers directly from feeds to staging_dir

Previous approach tried to compile Lua package but failed silently,
leaving no headers in staging_dir. This caused lucihttp to fail with:
  fatal error: lua.h: No such file or directory

Root cause: `make package/lua/compile || true` was failing but being
ignored, so headers were never installed to staging_dir.

New solution - Direct header installation:
1. Install lua package to feeds (./scripts/feeds install lua)
2. Find Lua source directory in feeds/packages/lang/lua/src/
3. Directly copy *.h headers to staging_dir/target-*/usr/include/
4. Verify lua.h exists before continuing

This avoids the complexity of compiling Lua and directly provides
the headers that lucihttp needs for compilation.

Fallback: If headers not found in feeds source, search build_dir
for any existing lua.h and copy it.

Changes:
- GitHub Actions: Completely rewrote header installation logic
- local-build.sh: Updated both Lua header installation sections
- Both: Added detailed verification and fallback mechanisms

This should finally resolve the persistent lucihttp compilation
failures in SDK builds.
