feat: native linux-x64-glibc module packages and reviewed license supplements (ADR 0049, ADR 0052)
Implements ADR 0049's deferred native target and ADR 0052's reviewed
license supplements. The proof case is a real module using sharp.
packageFormat stays 1, and `any` is unchanged.

Packager (@ekklesia/module-pack):
- --target linux-x64-glibc. Native or platform-specific packages, found by
  the same generic rule that refuses them in `any`, stay outside the bundle.
- Each native package's production closure is walked through its own
  dependencies, installed optionalDependencies that match the target, and
  required peers. It is copied as real files flat under node_modules/<name>,
  with no links, dev dependencies, declarations, source maps, or other
  platforms' packages. Missing or foreign-platform required dependencies,
  version conflicts, links, foreign machines, and Node.js range conflicts
  fail closed.
- runtime.nodeApi, nodeAbi, and libcVersion are read from the binaries by a
  small ELF reader: the addon's node_api_module_get_api_version_v1 and the
  newest GLIBC_ symbol version needed. No shelling out. A native target with
  no addon is refused.
- ADR 0052 supplements: package-provided material stays primary. An exact
  match on name, version, and ekklesia-content-v1 digest (sorted normalized
  paths with each file's size and SHA-256; no metadata) adds labelled
  material after the package's own. Any mismatch, a declared-licence
  conflict, or a malformed or unreviewed supplement file fails. Missing
  material with no supplement still fails.

Supplement for @img/[email protected]:
- 184 components and 143 unique texts, assembled from the exact upstream
  sources sharp-libvips v1.3.3 builds linux-x64 from: 27 C/C++ libraries,
  glib's gvdb, librsvg's Rust crates (reproduced with cargo tree), the Rust
  standard library at the rustc commit recorded in the binary, plus the
  LGPL-3.0, GPL-3.0, and MPL-2.0 texts. Each source is recorded with its
  SHA-256 in PROVENANCE.md.
- It pins digest ekklesia-content-v1:sha256:50647b0b…, which is identical
  from the installed copy and from the registry tarball.
- LGPL/MPL source-availability determinations stay open, as ADR 0052
  states. Nothing claims they are met.

Verifier (Core):
- linux-x64-glibc is accepted only on a host whose platform, arch, glibc
  family and version, and Node-API version (from Node itself) match.
- Every ELF file must be x86-64; every .node must be an ELF object.
- `any` packages now also refuse node_modules/ and ELF files.
- Contract: native metadata must state nodeApi or nodeAbi, and Linux targets
  libcVersion (ADR 0049).

Proof:
- A checked-in AGPL native fixture packs byte-identically from unrelated
  copies (8.86 MB) and verifies with Core's verifier.
- Extracted elsewhere, it runs a sharp resize and PNG round trip in an
  empty-environment process. Every resolution stays in the package, and
  only the package's addon and libvips plus host system libraries load.

Signage is untouched.

Cairo is free software.
Every source file in the implementation[*] of cairo is available to be
redistributed and/or modified under the terms of either the GNU Lesser
General Public License (LGPL) version 2.1 or the Mozilla Public
License (MPL) version 1.1. Some files are available under more
liberal terms, but we believe that in all cases, each file may be used
under either the LGPL or the MPL.
See the following files in this directory for the precise terms and
conditions of either license:
COPYING-LGPL-2.1
COPYING-MPL-1.1
Please see each file in the implementation for copyright and licensing
information, (in the opening comment of each file).
[*] The implementation of cairo is contained entirely within the "src"
directory of the cairo source distribution. There are other components
of the cairo source distribution (such as the "test", "util", and "perf")
that are auxiliary to the library itself. None of the source code in these
directories contributes to a build of the cairo library itself, (libcairo.so
or cairo.dll or similar).
These auxiliary components are also free software, but may be under
different license terms than cairo itself. For example, most of the
test cases in the perf and test directories are made available under
an MIT license to simplify any use of this code for reference purposes
in using cairo itself. Other files might be available under the GNU
General Public License (GPL), for example. Again, please see the COPYING
file under each directory and the opening comment of each file for copyright
and licensing information.
