Wild Dragon Dev 0d479d043d feat(framecache): phase 2 — deltacast-bridge writes to shm ring
- fc_writer.h/fc_writer.c: new framecache slot writer module
  - Registers slot via POST /slots to framecache HTTP API on signal lock
  - Opens shm file returned by API (O_RDWR + mmap MAP_SHARED)
  - fc_writer_write(): atomic write_cursor advance + sem_post per frame
  - fc_writer_close(): DELETE /slots/:id + munmap + sem_close
  - HTTP calls via raw POSIX sockets (no libcurl dependency)
  - Parses host:port from FC_URL env var or --fc-url arg

- main.c changes:
  - PortState gains slot_id, fc_url, fc_writer fields
  - --fc-url CLI arg + FC_URL env var (default http://localhost:7435)
  - On signal lock: fc_writer_open() before thread launch;
    falls back to FIFO if framecache unreachable (fc_writer == NULL)
  - video_thread: shm path primary (fc_writer != NULL),
    FIFO path fallback (fc_writer == NULL or LEGACY_FIFO=1)
  - Format JSON now includes slot_id field for node-agent consumption
  - Cleanup: fc_writer_close() before VHD_CloseBoardHandle

- CMakeLists.txt:
  - Add fc_writer.c to build
  - Link rt (shm_open, sem_open)
  - LEGACY_FIFO option (OFF by default) for nodes without framecache

Audio thread unchanged — audio stays in FIFO (shm audio is roadmap).
