www/pomerium-envoy-custom: update to 1.37.0.20260618
Update pomerium-envoy-custom to commit 16ede7a56f2f (envoy f387231af8).
Major changes for this version bump:
- Remove obsolete FreeBSD patches (ares, zlib, zstd cmake targets removed upstream; luajit_build.sh and -GNinja already upstream)
- Regenerate remaining FreeBSD patches for new envoy source
- Replace envoy_toolshed stub with real extraction (v0.3.35)
- Remove rules_oci (not needed for FreeBSD binary build)
- Remove custom LLVM toolchain; use system Clang via --extra_toolchains=@local_config_cc//:all
- Add --override_repository for renamed repos (re2, yaml-cpp, brotli, etc.)
- Add FreeBSD support to toolchains_llvm v1.7.0
- Add FreeBSD support to pomerium's luajit.bzl platform detection
- Create FreeBSD-specific openssh config.h
- Fix LuaJIT getentropy conflict with FreeBSD SSP headers
- Build nghttp2 from source (envoy patches add custom API)
- Add FreeBSD to rules_foreign_cc cmake generator detection
- Add transitive deps to DISTFILES (helly25_bzl, tar.bzl, jq.bzl, yq.bzl, argparse, aspect_bazel_lib, nghttp2 source)
- Update stale GH_TUPLE versions (dd_trace_cpp, libcircllhist, vpp_vcl, etc.)
- Link with -lgcc_eh for LuaJIT dynamic EH frame symbols
