Christian Nennemann 372dd67a3b feat: add OpenWrt cross-compilation and packaging (Phase F7)
- packaging/openwrt/: opkg Makefile, procd init script, uci config
- scripts/cross-compile.sh: build for musl targets with size checks
- .github/workflows/openwrt.yml: CI cross-compile + 5 MB size gate
- docs/openwrt.md: installation and configuration guide
- Targets: x86_64-musl, armv7-musleabihf, aarch64-musl
- Uses cargo-zigbuild for Docker-free cross-compilation

# Cross-compile quicproquo for musl targets (OpenWrt / embedded Linux).
#
# Produces statically linked, stripped binaries optimised for size.
# Requires: cargo-zigbuild (preferred) or cross.
#
# Usage:
# ./scripts/cross-compile.sh # all targets
# ./scripts/cross-compile.sh x86_64-unknown-linux-musl # single target
#
# Output: target/<triple>/release/qpq-server (stripped)
