fix: comprehensive boot hardening — crashes, warnings, sensors, bare-metal PS/2

- firmware-loader: handle missing INIT_NOTIFY gracefully (Option<RawFd>)
- driver-params: suppress ENODEV (19) on missing driver-manager scheme
- compositor: add wl_seat.name + pointer capabilities for Qt6 compat
- greeter: use redox QPA (libqredox.so) instead of broken Qt6 Wayland
- greeter: reduce DRM wait 10s→2s, kded6 offscreen QPA to avoid crash
- thermald: add CPU die temperature via MSR IA32_THERM_STATUS (Linux coretemp)
- pcid: diagnostic MCFG warning with Q35 guidance, address validation
- dhcpd: auto-interface detection (P0-dhcpd-auto-iface.patch wired)
- procmgr: SIGCHLD EPERM→debug (kernel limitation, not a bug)
- ps2d LED: warn→debug on modern hw without real PS/2 controller
- ps2d mouse: 10×1s→3×250ms retry, fast-fail on unknown response
- i2c RON: handle empty response from i2cd when no adapters present
- base recipe: wire 6 new/improved patches
- config: remove INIT_SKIP, enable all 14 previously-suppressed daemons
