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.

+# Replace unwrap() in Daemon::ready() with graceful error handling.
+# When hwd or pcid-spawner spawns a daemon fire-and-forget (dropping the
+# pipe's read end before the child signals readiness), the unwrap() causes
+# a BrokenPipe panic that kills the child and cascades into boot failures.
+#
+# The write may fail because init already closed the read end (service
+# timeout, duplicate start, or oneshot completion). In all cases the
+# daemon should continue running rather than panic.
