Subject: [PATCH] Fix build script path resolution for customer Makefile usage

- Added BUILD_DIR=/home/teknari/Sync/Programming/VibeCoding/nostr_core_lib to capture absolute build directory
- Changed relative paths to absolute paths in archive extraction
- Fixes 'No such file or directory' error when build.sh is called from customer Makefiles
- Maintains backward compatibility for all existing use cases
