Snapshot protocol for late-joining subscribers
C-compatible public API (bacaro.h) with 17 functions
oste monitoring tool (prints all property updates with timestamps)
vecio CLI tool (sets a single property and exits, with optional -w delay)
7 test suites covering wire format, cache, lifecycle, discovery, snapshot, pub/sub, batch read
CI via GitHub Actions (Debug + Release, Ubuntu)

No persistence — properties exist only in process memory
Linux only (epoll, inotify)
