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.
