refactor: deconsolidate redox.patch into individual patches

The 556MB monolithic redox.patch was impossible to manage, unreviewable,
blocked GitHub pushes, and could only grow. This commit:

- Moves all 64 absorbed patches from absorbed/ to active use in base/
- Removes the absorbed/ directory (consolidation history is now PATCH-HISTORY.md)
- Removes the redox.patch symlink from recipes/core/base/
- Fixes all recipe symlinks to point to active patches (not absorbed/)
- Patches are now individually wired, reviewable, and independently rebasable

The redox.patch mega-file is no longer needed — individual patches
are applied directly from the recipe.toml patches list.
