vasilito cb424d7448 build: static patch-sanity linter (shift-left the malformed-patch class)
verify-patch-sanity.py validates every active recipe .patch has internally-
consistent hunk line counts — catching the 'malformed patch at line N' failure
at commit/CI/preflight time instead of hours into a cook. This cycle hit that
class three times (qtwaylandscanner, sddm, xwayland), each only discovered when
cookbook tried to apply the patch.

Running it across the repo found 29 latent malformed patches (validated against
GNU patch: e.g. relibc/P3-sysv-ipc reproduces 'malformed patch at line 22').
They were harmless only because they sit in vendored recipes (baked, not re-
applied) — but would fail on any version-bump re-derivation. --fix recounts the
hunk headers (body untouched) and repaired all 29.

Wired into build-preflight.sh (Phase 1.0D) and redbear-ci.yml, with a unit test
(test-patch-sanity.sh). Skips archived/legacy trees and unvalidatable formats
(empty placeholders, bare-@@ git hunks).

llvm-cgdata - LLVM CodeGen Data Tool
====================================
.. program:: llvm-cgdata
SYNOPSIS
--------
:program:`llvm-cgdata` [**commands**] [**options**] (<binaries>|<.cgdata>)
DESCRIPTION
-----------
The :program:llvm-cgdata utility parses raw codegen data embedded in compiled
binary files and merges them into a single .cgdata file. It can also inspect
and manipulate .cgdata files. Currently, the tool supports saving and restoring
outlined hash trees and stable function maps, allowing for more efficient
function outlining and function merging across modules in subsequent
compilations. The design is extensible, allowing for the incorporation of
additional codegen summaries and optimization techniques.
COMMANDS
--------
At least one of the following commands are required:
.. option:: --convert
Convert a .cgdata file from one format to another.
.. option:: --merge
Merge multiple raw codgen data in binaries into a single .cgdata file.
.. option:: --show
Show summary information about a .cgdata file.
OPTIONS
-------
:program:`llvm-cgdata` supports the following options:
.. option:: --format=[text|binary]
Specify the format of the output .cgdata file.
.. option:: --output=<string>
Specify the output file name.
.. option:: --cgdata-version
Print the version of the llvm-cgdata tool.
EXAMPLES
--------
To convert a .cgdata file from binary to text format:
$ llvm-cgdata --convert --format=text input.cgdata --output=output.data
To merge multiple raw codegen data in object files into a single .cgdata file:
$ llvm-cgdata --merge file1.o file2.o --output=merged.cgdata
To show summary information about a .cgdata file:
$ llvm-cgdata --show input.cgdata
