v0.9.2: complete standalone Proxy distribution

[0.9.2] — 2026-08-17

A packaging-only maintenance release completing the standalone Forge Proxy
distribution introduced in 0.9.1. Forge’s forwarding, routing, backend, and
guardrail behavior is unchanged.

Fixed

• Platform release builds are exercised before publication. Proxy release
  pull requests build Windows x64, Linux x64/glibc, and macOS ARM64 artifacts
  through their documented platform entrypoints, then retain the exact tested
  bytes as one release candidate.
• Linux artifacts use the declared compatibility build. The published Linux
  executable is produced by the Ubuntu 24.04/Python 3.14 Docker build and those
  same bytes are exercised on Ubuntu 24.04, Debian 13, and Fedora 43.
• Proxy publication no longer rebuilds release artifacts. Post-merge
  publication verifies the retained candidate against the release tag and
  uploads it unchanged, with direct asset identities available for rollback.
