fix: KF6 config, kwin stub, docs, greeter, I2C/GPIO drivers, bootstrap

- KF6 config: enable 31 KF6 frameworks + kdecoration + kglobalacceld
  (was only kwin stub; 22 additional recipes now enabled)
- KWin: honest #TODO naming real blockers (Qt6::Sensors WIP,
  libinput ignored, no canberra); kwin_wayland shim delegates to
  redbear-compositor
- Greeter: enable redbear-greeterd replacing /usr/bin/true stub
- Mini config: suppress curl/git/mc (broken deps, not boot-critical)
- Docs: fix KF6 count (9->31 enabled), kwin status (stub, not real
  build), plasma blocked, config surface accuracy across

- P2-i2c-gpio-ucsi-drivers.patch: 10 I2C/GPIO/UCSI daemon sources
  (gpiod, i2cd, dw-acpi-i2cd, intel-lpss-i2cd, i2c-gpio-expanderd,
  intel-gpiod, i2c-hidd, ucsid, i2c-interface, acpi-resource);
  amd-mp2-i2cd + intel-thc-hidd excluded (PCI API changed)
- P0-bootstrap-workspace-fix.patch: empty [workspace] in bootstrap
  Cargo.toml prevents auto-detection of parent workspace (fixes
  base-initfs from-scratch build)
- QEMU boot verified: kernel -> PCI -> NVMe -> ACPI -> display ->
  networking -> services -> RB_SERIAL_PROBE_OK

The recipe no longer injects fake QtNetwork headers into the shared sysroot; instead it uses source-local Redox compatibility headers for the bounded `QHostAddress` / `QHostInfo` surface KIOCore still needs.

 ## Bottom Line
 
 The Red Bear desktop stack has crossed major build-side gates and one important bounded runtime gate:
-- All Qt6 core modules, all 32 KF6 frameworks, Mesa EGL/GBM/GLES2, and D-Bus build
+- All Qt6 core modules, all 32 KF6 recipes, Mesa EGL/GBM/GLES2, and D-Bus build — **but only 9 KF6 frameworks reach the built image** (config gap: 22 additional recipes exist with real builds but are not enabled)
 - Three supported compile targets exist, with desktop/graphics on `redbear-full`
-- the Red Bear-native greeter/login path now has a bounded passing QEMU proof (`GREETER_HELLO=ok`, `GREETER_INVALID=ok`, `GREETER_VALID=ok`)
+- the Red Bear-native greeter/login path now has a bounded passing QEMU proof (`GREETER_HELLO=ok`, `GREETER_INVALID=ok`, `GREETER_VALID=ok`) — but the greeter service is currently **disabled** in config (runs `/usr/bin/true` instead of `redbear-greeterd`)
 - relibc compatibility is materially stronger than before
 - Phase 1 test coverage is comprehensive: 300+ unit tests across all Phase 1 daemons (evdevd 65, udev-shim 15, firmware-loader 24, redox-drm 68, redbear-hwutils 79 host + 12 Redox-cfg-gated, bluetooth/wifi 209); service presence probes (`redbear-info --probe`) and 4 check binaries (`redbear-phase1-{evdev,udev,firmware,drm}-check`) validate Phase 1 substrate; 6 C POSIX tests (`relibc-phase1-tests`) exercise relibc compatibility layers
-- KWin recipe provides cmake config stubs and wrapper scripts delegating to redbear-compositor; real KWin build requires sufficient Qt6Quick/QML proof (qtdeclarative exists, downstream unproven); no compositor session proof exists
-- Critical blockers for Phase 4: kirigami stub (needs Qt6Quick). kf6-knewstuff/kwallet now have real cmake build attempts (enabled in config). QtNetwork surface remains disabled for network-aware KDE features.
+- KWin recipe is a **stub** — downloads real KWin v6.3.4 source but build script never compiles it; delegates to redbear-compositor via wrapper
+- Critical blockers for Phase 4: KWin must become real (currently stub); plasma packages blocked by kf6-knewstuff (needs QtNetwork); 22 additional KF6 recipes need explicit config enablement
 
-The remaining work is **broader runtime validation, compositor/session stability, and the remaining KDE session/runtime proof work**.
-Phase 1 (Runtime Substrate Validation) has comprehensive test coverage; the remaining gate is live-environment runtime validation. The key boundary for Phase 2 is: no compositor session proof exists. The key boundary for Phase 3-4 is: kirigami must become honest (needs Qt6Quick downstream proof), while full KDE network features still wait on QtNetwork. kf6-knewstuff/kwallet now have real build attempts.
