submodules: update Cat 2 fork pointers to local path deps and +rb0.2.5

- relibc: variadic sem_open and local fork path deps
- base: already at latest RedBear-OS submodule/base
- bootloader/kernel/libredox/userutils: pushed local path-dep fixes
- installer/redoxfs: diverged from remote submodule/*; local commits saved,
  divergence to be resolved after build
- driver-manager: add syscall path dependency
- AGENTS.md: document +rb build metadata and no-patches-for-local-forks rule
- remove dead patch symlinks from recipes/core/relibc (path-source local fork)

+### Local fork recipe directories must not carry patch files
+
+When a recipe's `[source]` uses `path = ".../local/sources/<component>/"`, the local fork
+**is** the patch. The recipe directory (`recipes/core/<component>/`) **MUST NOT** contain
+`.patch` files or symlinks. Patch files from the pre-fork era must be applied as commits to
+the `submodule/<component>` branch (or, if kept for historical reference, archived under
+`local/docs/archived/` or `local/patches/archived/` and never symlinked into a recipe
+directory). Leaving patch files in a `path`-source recipe directory creates the false
+impression that the build system applies them, which leads to exactly the kind of duplicate
+fix work we just saw with `sem_open`.
+
+The cookbook **does not apply patches for `path` sources**. If a component needs patches,
+it must use a `git` source pointing at a `submodule/<component>` branch, or the patches
+must be merged into the local fork branch.

 ### GOLDEN RULE — Red Bear adapts to upstream, never the reverse
 
 **When upstream Redox changes a dependency version, API, or ABI, Red Bear adapts.**
