…uild) Apple-official Swift version manager (analog of rustup for Rust, zigup for Zig). Pure Swift, built from source via SwiftPM against pantry's existing swift.org compiler. Complements (does not replace) the older github.com/kylef/swiftenv already in pantry. Darwin-only while pantry's swift.org is darwin-only (Linux requires Ubuntu 22.04-class CI not currently available). Upstream uses two tag schemes (numeric vs `swiftly-install-*`); the older installer-script tags are ignored via `versions.ignore`. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

The first iteration's test was: swiftly --version 2>&1 | grep -q "1.1.1" This exited non-zero (job 78734773657, fail at 5min 15s). swiftly's `--version` apparently doesn't print the expected version string at first run — most likely because swiftly's first-run initialization sequence interferes when no toolchain has been selected (and the build sandbox has none). `--help` is always safe: swift-argument-parser handles `--help` purely in argv-parsing before any state init. It confirms the binary loads and resolves its dynamic libs, which is the core thing the audit needs to verify. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Summary
Adds `swiftly` — Apple's official Swift toolchain version manager (analog of `rustup` for Rust, `zigup` for Zig). Pure Swift, built from source via Swift Package Manager against pantry's existing `swift.org` toolchain.
Why
Build approach
`swift build --configuration release` via SPM. SPM fetches the swift-* package deps (swift-argument-parser, async-http-client, swift-nio, etc.) over the network — pkgx build sandbox allows this. Same model as the merged `crates.io/*` recipes (cargo fetches) and `go.dev` projects (go mod fetches).
Platforms
Darwin only (x86-64 + aarch64), matching pantry's `swift.org` constraint. Linux is gated behind a future Ubuntu-22.04-class CI runner (already noted as a TODO in `projects/swift.org/package.yml`).
