v4.2.1: Signed checksums and PATH export fix

A small patch release with two user-facing fixes: mise downloads are now verified against minisign-signed release checksums by default, and the env input no longer leaks the runner's PATH into subsequent steps.

Fixed

Verify mise downloads with signed checksums (#548) by @​jdx

The action now embeds mise's minisign public key and verifies SHASUMS256.txt.minisig before trusting any release checksums, then checks the downloaded mise binary's SHA256 against the verified list. This applies to both GitHub release archives (verified before extraction) and the default mise.jdx.dev CDN path (verified against the signed checksum for the matching release asset). If a CDN download fails verification, the action warns and falls back to the signed GitHub release asset instead of installing an unverified binary.

• The existing sha256 input still works as an explicit override.
• Pinned mise versions older than 2024.12.24 (which predate minisign checksums) get a warning and skip signed verification rather than failing.
• Because tar installs now extract from a verified file on disk, the previous streaming download | tar fast path is replaced with a download-then-verify-then-extract flow.

Thanks to @​potiuk for the detailed threat-model writeup in #547.

Exclude PATH from environment export (#556) by @​jdx

The env input has always documented that "PATH modifications are not part of this", but since the switch to mise env --json in #252 (needed for redaction support), the action was exporting every string value returned by mise — including the computed PATH — into GITHUB_ENV. That effectively snapshotted the runner's entire PATH into subsequent steps and let [env] _.path entries in mise.toml leak past the action's own PATH management.

exportMiseEnv now skips PATH (case-insensitive) when exporting JSON env vars, restoring the documented behavior. Normal mise env vars are still exported, and PATH continues to be managed by the action's own setup (e.g. add_shims_to_path). Fixes #555.

v4.2.0: Bootstrap mode & wget fallback

This release adds an opt-in bootstrap mode for projects that use mise bootstrap, and makes the action work on runner images that ship wget but not curl.

Added

Bootstrap mode (#522) by @​jdx

Three new inputs let the action drive mise bootstrap instead of mise install:

- uses: jdx/mise-action@v4
  with:
    bootstrap: true
    bootstrap_skip: "tools,task"   # comma-separated parts to skip
    bootstrap_args: "--yes"        # extra args forwarded to mise bootstrap

• When bootstrap: true, the action runs mise bootstrap under the existing install gate and sets MISE_EXPERIMENTAL=1 automatically.
• If a repo mise lock file is present, it runs mise --locked bootstrap, matching the auto-lock behavior introduced for mise install in v4.1.0.
• install_args cannot be combined with bootstrap: true — the action fails fast and tells you to use bootstrap_skip / bootstrap_args instead, because full bootstrap doesn't support partial tool install args.
• A new {{bootstrap_hash}} template variable is included in the default cache key (and available in custom cache_key templates) so bootstrap and non-bootstrap configurations don't share caches.

bootstrap_skip relies on mise bootstrap --skip from jdx/mise#10497, so make sure you're on a recent mise version if you use it.

Fixed

• Fall back to wget when curl is unavailable (#521) by @​risu729 — The action used to hard-code curl for fetching the mise binary, tar/zip archives, and the latest VERSION lookup, which broke on minimal runner images that only ship wget. It now prefers curl and transparently falls back to wget, preserving the streaming download | tar fast path for .tar.gz and .tar.zst installs on Linux/macOS. Proxy support is unchanged — both tools honor HTTP_PROXY/HTTPS_PROXY. Addresses jdx/mise#10488.
