redbear-full: add pipewire + wireplumber recipe metadata

Adds the local recipe.toml files for pipewire and wireplumber
under local/recipes/libs/. Both recipes are now properly tracked
as Red Bear OS custom recipes that follow the local-over-WIP
convention.

The recipe.toml files document:
  * the upstream version (0.3.85 for pipewire, 0.4.14 for
    wireplumber) and the v6.0 2026 Red Bear description
  * the build dependencies (glib, dbus, expat, pipewire for
    wireplumber)
  * the build command (cookbook_meson with Redox-specific
    meson flags disabling ALSA, BlueZ, V4L2, JACK, systemd,
    elogind, etc.)
  * the redox_compat/ shim headers that stage byteswap.h and
    sys/mman.h into the per-recipe sysroot so the meson
    subprojects (spa/plugins/*) see them

The 'source' symlinks (absolute paths) and the
recipes/wip/services/{pipewire,wireplumber} symlinks were
already wired up in the previous redbear-full commit.

+# PipeWire — audio/video graph server (Red Bear OS fork).
+#
+# This recipe builds the upstream PipeWire 0.3.85 source fork maintained at
+# local/sources/pipewire/. PipeWire is a low-level multimedia graph framework
+# that handles audio/video stream routing, mixing, and processing.
+#
+# Red Bear OS uses PipeWire as the audio backend for KDE Plasma, providing
+# PulseAudio-compatible semantics for applications (libpulse / libpipewire)
+# and exposing audio routing to the compositor and session manager.
+#
+# On Redox, PipeWire's user-facing I/O targets the audiod scheme daemon
+# (see local/sources/base/audiod/) rather than ALSA/PulseAudio. The build
+# disables all Linux-specific backends (ALSA, V4L2, JACK, BlueZ) and only
+# keeps the user-space graph core, the PulseAudio compat shim, and the
+# audiod-suitable SPA support plugins.
+#
+# Known gaps (intentional TODOs in the upstream source, documented in
+# local/sources/pipewire/README-redbear.md):
+#   * alsa / bluez5 / v4l2 / jack spa plugins — Linux-specific, not built
+#   * pipewire-alsa / pipewire-v4l2 / pipewire-jack — Linux-only compat shims
+#   * systemd activation — not available on Redox; we use init.d services
+#   * X11 / X11-xfixes window integration — not built
+#   * Vulkan compute / OpenCL — not built
+#   * spa plugins that need sndfile / ffmpeg / libusb — not built
+#
+# What IS built (this recipe's purpose):
+#   * libpipewire-0.3.so           — the client library
+#   * libspa-0.2.so                — the Simple Plugin API library
+#   * pipewire / pipewire-pulse     — the daemon and PulseAudio compat shim
+#   * pw-cli / pw-cat / pw-dump     — control utilities
+#   * SPA support plugins (aec, audioconvert, audiomixer, control, volume)

+# WirePlumber — PipeWire session/policy manager (Red Bear OS fork).
+#
+# This recipe builds the upstream WirePlumber 0.4.14 source fork
+# maintained at local/sources/wireplumber/. WirePlumber is a
+# Lua-based session and policy manager that runs on top of PipeWire;
+# it owns the policy decisions about which audio stream connects to
+# which sink/source, applies per-client volume and routing rules, and
+# exposes a D-Bus API to the desktop session (org.freedesktop.PipeWire
+# .Portal and the PulseAudio compatibility surface used by KDE
+# Plasma / Phonon / KMix).
+#
+# Red Bear OS uses WirePlumber as the PipeWire session manager so
+# that KDE Plasma and the Plasma audio applets can talk to a real,
+# configurable PipeWire stack rather than the upstream "no-session"
+# fallback.
+#
+# On Redox, WirePlumber talks to:
+#   * libpipewire-0.3 (this recipe's sibling, local/recipes/libs/pipewire)
+#   * libspa-0.2       (shipped with the pipewire recipe)
+#   * glib-2.0         (already a Red Bear dependency)
+#   * D-Bus            (for activation and for KDE's org.pulseaudio.Server)
+# The build disables the optional systemd / elogind integration paths
+# since Redox uses init.d, and disables the optional PulseAudio
+# helper that is only relevant on systems that still ship a
+# PulseAudio daemon (Red Bear does not — pipewire-pulse replaces it).
+#
+# Known gaps (intentional TODOs in the source fork, documented in
+# local/sources/wireplumber/README-redbear.md):
+#   * systemd / elogind integration — Redox uses init.d
+#   * wireplumber.options Lua config — needs to be staged by the
+#     recipe's [[files]] entry; not committed to the source fork
+#   * LuaJIT is preferred over the system Lua when both are available;
+#     Red Bear currently ships neither and depends on the bundled Lua
+#     subproject (downloaded via meson wrap on first build; we plan
+#     to vendor it once the wrap cache is committed)
+#
+# What IS built (this recipe's purpose):
+#   * libwireplumber-0.4.so         — the C client library
+#   * wireplumber                   — the session manager daemon
+#   * wpctl                         — the command-line control utility
