- 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

+ * Functions which do automatically cancel operations or release resources upon
+ * driver detach.
+ *
+ * These should be helpful to avoid mixing the manual and devm-based resource
+ * management which can be source of annoying, rarely occurring,
+ * hard-to-reproduce bugs.
+ *
+ * Please take into account that devm based cancellation may be performed some
+ * time after the remove() is ran.
+ *
+ * Thus mixing devm and manual resource management can easily cause problems
+ * when unwinding operations with dependencies. IRQ scheduling a work in a queue
+ * is typical example where IRQs are often devm-managed and WQs are manually
+ * cleaned at remove(). If IRQs are not manually freed at remove() (and this is
+ * often the case when we use devm for IRQs) we have a period of time after
+ * remove() - and before devm managed IRQs are freed - where new IRQ may fire
+ * and schedule a work item which won't be cancelled because remove() was
+ * already ran.
