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
  CONSOLE-TO-KDE-DESKTOP-PLAN, DESKTOP-STACK-CURRENT-STATUS,
  local/AGENTS
- 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

-# KWin Wayland compositor — real cmake build attempt with reduced feature set.
-# DRM backend → scheme:drm, libinput → via evdevd, session → seatd.
-# Full build requires Qt6Quick/QML (qtdeclarative exports metadata but downstream QML insufficient).
-# Requires real cmake configure + build; recipe fails hard if configure/build fails.
+#TODO: KWin remains a Red Bear transition stub for now. Upstream 6.3.4 lets us disable X11,
+# KCMs, screenlocker, tabbox, global shortcuts, runners, and notifications, but the top-level
+# CMake still hard-requires non-X11 pieces that are not part of the tracked Red Bear build
+# surface yet: Qt6::Sensors is only available as an uncompiled WIP recipe, libinput is still a
+# WIP port and is explicitly ignored in config/redbear-full.toml, and there is no canberra recipe
+# in-tree.
+# This recipe therefore does NOT invoke upstream CMake yet; it only stages
+# redbear-compositor-backed kwin_wayland/kwin_wayland_wrapper shims plus the minimal
+# KF6WindowSystem/KF6Config CMake config stubs consumed by downstream KDE recipes during the
+# transition.
