fix(aqua): extract 7z archives

[risu729]

Summary

• route aqua format: 7z archives through the existing archive extractor
• detect .7z assets in the aqua registry mirror when format is omitted
• add Windows e2e coverage using a small local aqua registry and the existing 7z fixture

References

• Addresses `mise use -g aqua:ImageMagick/ImageMagick` fails with `unsupported format: 7z` #10215 (aqua:ImageMagick/ImageMagick failed with unsupported format: 7z)
• Unblocks registry: add imagemagick backend aqua:ImageMagick/ImageMagick for Windows support #10214, the mise registry PR adding aqua:ImageMagick/ImageMagick for Windows support; that PR exposed that mise's aqua backend did not support 7z extraction
• Aqua registry reference: Add ImageMagick/ImageMagick aquaproj/aqua-registry#50281 added ImageMagick/ImageMagick to aqua, where aqua can install the Windows .7z release assets

Testing

• cargo fmt --all -- --check
• git diff --check
• Attempted cargo test -p aqua-registry test_format_detects_7z_asset, but local execution was blocked for an extended period by the shared Cargo build-directory lock from other worktrees; CI should cover this path
• Windows Pester e2e not run locally on Linux

Summary by CodeRabbit

• New Features

  • Added support for 7z archive format detection to recognize and handle 7z compressed archives
  • Implemented Windows-optimized extraction handling for 7z packages ensuring proper decompression and installation

• Tests

  • Added end-to-end test suite validating 7z package installation workflow on Windows
  • Test coverage includes local registry configuration, tool installation, and execution verification

📝 Walkthrough

Walkthrough

This PR adds 7z archive format support to the Aqua package manager backend. Format detection recognizes .7z extensions with a unit test validating the detection. The extraction logic on Windows routes 7z through the untar-based path, and an end-to-end test verifies the complete install and execution workflow with a bundled 7za.exe fixture.

Changes

7z Archive Format Support

Layer / File(s)	Summary
7z format detection crates/aqua-registry/src/types.rs	detect_format recognizes .7z extensions (reformatted across lines without functional change), and a unit test asserts that assets ending in .7z return format "7z".
Windows extraction routing src/backend/aqua.rs	The AquaBackend::install extraction condition now includes format == "7z" on Windows to route 7z archives through the untar-based extraction path.
End-to-end test e2e-win/7z.Tests.ps1	A Windows test suite sets up a local registry with a 7za.exe fixture, overrides Aqua environment variables, runs mise install, and validates mise x aqua:example/7zip -- 7za outputs the expected 7-Zip version.

🐰 A seven-zee archive hops on by,
Format detected, extraction's nigh,
Windows paths unfold with care,
Testing proves it's working there! 🎯

Greptile Summary

This PR adds 7z archive support to the aqua backend by routing format == "7z" through the existing file::untar / un7z path on Windows and detecting .7z extensions in detect_format when the format field is omitted from the registry entry.

• crates/aqua-registry/src/types.rs: Inserts "7z" into the detect_format suffix array (between "zip" and "gz", where ordering doesn't conflict), and adds a unit test for the new detection path.
• src/backend/aqua.rs: Extends the tar-branch condition to format.starts_with("tar") || (format == "7z" && cfg!(windows)); on non-Windows the compile-time guard evaluates to false, so a 7z format still hits bail!("unsupported format: {}") as expected.
• e2e-win/7z.Tests.ps1: Adds a Windows Pester test that bootstraps a local aqua registry, installs example/7zip from the existing test fixture, and validates end-to-end extraction.

Confidence Score: 5/5

Safe to merge — the change is narrowly scoped to the aqua 7z path, the Windows-only guard is expressed at compile time, and non-Windows behaviour is unchanged.

All three changed files are small and self-contained. The cfg!(windows) guard correctly prevents the new code path from executing on non-Windows hosts, the format detection insertion doesn't conflict with any existing suffix, and the e2e test exercises the full install-and-execute flow against a real fixture.

No files require special attention.

Important Files Changed

Filename	Overview
crates/aqua-registry/src/types.rs	Adds "7z" to the detect_format suffix list so packages with .7z URLs/assets are correctly identified when format is omitted; adds a unit test covering the new detection path.
src/backend/aqua.rs	Routes format=="7z" through file::untar on Windows via a cfg!(windows) compile-time guard; on non-Windows the condition is false and execution correctly falls through to the existing bail!("unsupported format") arm.
e2e-win/7z.Tests.ps1	Adds a Windows Pester e2e test that spins up a local aqua registry pointing at the existing 7z test fixture, installs via the aqua backend, and verifies 7za executes correctly; env vars are saved/restored cleanly in AfterAll.
