restore lost packages from 0.2.3 + fix overwritten 0.2.4 files

Browse Source 
- 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

* RPC client per-operation statistics provide latency and retry
* information about each type of RPC procedure in a given RPC program.
* These statistics are not for detailed problem diagnosis, but simply
* to indicate whether the problem is local or remote.
*
* These counters are not meant to be human-readable, but are meant to be

* such, the counters are sampled by the tools over time, and are never
* zeroed after a file system is mounted. Moving averages can be computed
* by the tools by taking the difference between two instantaneous samples
* and dividing that by the time between the samples.
*
* The counters are maintained in a single array per RPC client, indexed
* by procedure number. There is no need to maintain separate counter
* arrays per-CPU because these counters are always modified behind locks.

*
* x1:x2:x3:x4:x5:x6:x7:x8.p1.p2
