feat: PS4RP daemon source + working PS4 build

Full daemon source (C, PS4 native):
- log/cfg/jsonlite/b64: logging, /data/PS4RP/config.json, JSON, base64
- http.c: OAuth2 token exchange via SceHttp (authorization_code + refresh)
- ws.c: WebSocket over SceNet + LibreSSL (SSLv23_client_method),
  DNS via sceNetResolverStartNtoa, OrbisNetSockaddr packing
- discord.c: gateway connect/identify/heartbeat/presence set+clear
- detect.c: foreground game via sceUserServiceGetForegroundUser
  + app.xml/app.db title-name resolution
- main.c: poll loop (config poll_interval_s)

Build verified on macOS (LLVM 21 + OpenOrbis toolchain v0.5.4):
- 9 objects compile, lld 21 links build/ps4rp.elf (169KB)
- create-fself produces valid SCE ASLR payload build/ps4rp.fself
- libSceLibreSSL exports the OpenSSL-style TLS API used by ws.c
