restore lost packages from 0.2.3 + fix overwritten 0.2.4 files

- Restore 29 recipe symlinks (libdrm, qtbase, dbus, sddm, pipewire, etc.)
- Restore 33 patches (KDE, libdrm, mesa, pipewire, sddm, wireplumber)
- Restore 20+ local/scripts (audit, lint, test, build helpers)
- Restore src/cook/scheduler.rs, status.rs, gnu-config/
- Restore scripts/patch-inclusion-gate.sh, run_mini1.sh, validate-collision-log.sh
- Recover TLC source from HEAD (was overwritten by 0.2.3 checkout)
- Recover 11 local/docs plans from HEAD (were overwritten)
- Recover qt6-wayland-smoke symlink from HEAD
- Fix MOTD: remove garbled ASCII art, use clean text
- Update version: 0.2.0 -> 0.2.4 in os-release, motd, config
- Reduce filesystem_size: 1536 -> 512 MiB
- Add ABSOLUTE RULE to AGENTS.md: never delete/ignore packages
- Reduce pcid scheme log verbosity: info -> debug

+ * @cleanup:		Cleanup callback (can be NULL).
+ * @data_present:	Callback to determine if data is available
+ *			on the RNG. If NULL, it is assumed that
+ *			there is always data available.  *OBSOLETE*
+ * @data_read:		Read data from the RNG device.
+ *			Returns the number of lower random bytes in "data".
+ *			Must not be NULL.    *OBSOLETE*
+ * @read:		New API. drivers can fill up to max bytes of data
+ *			into the buffer. The buffer is aligned for any type
+ *			and max is a multiple of 4 and >= 32 bytes.
+ * @priv:		Private data, for use by the RNG driver.
+ * @quality:		Estimation of true entropy in RNG's bitstream
+ *			(in bits of entropy per 1024 bits of input;
+ *			valid values: 1 to 1024, or 0 for maximum).
