commit 6a492bc4c54d87f4fa8e767141d0eba9d3f12e5f

bxhkd.c: Implement command dispatch and harden socket logic.

  - Add dispatch logic in keypress() to route local commands
    to spawn() and socket commands to send_cmd(), using the local
    flag from theHotkey struct.
  - Fix -Wsign-compare warning by changing loop variable to size_t.
  - Add NULL check on getenv("HOME") in send_cmd().
  - Mark send_cmd parameter as const.
  - Replace hardcoded socket path with SOCKET_SUFFIX macro.
