release — tiered compatibility & release workflow

A config-driven release orchestrator. Mechanics live in scripts/release.py (unit-tested, stdlib-only); this file is the workflow you (or an agent) follow. Read reference/config-schema.md for release.config.json and reference/standards.md for why each step exists.

Scope honesty: reference-tested on a Tauri + Rust + SvelteKit repo (Cull). Other stacks are supported by config, not yet validated. Treat first runs on a new stack as a dry run (see "Dry run" below) until you trust it.

When to use

The user says "release", "ship it", "cut a version", "bump version", "tag a release", "update the changelog/COMPATIBILITY". Requires a release.config.json at the repo root (scaffold from templates/release.config.json.tmpl).
