Summary

Issue #138 asked to keep mise.macos-x64.lock in sync on mr-boxington bumps. While working on it, I found that on Intel macOS plain mise install and mise lock already exit 1 with the current lockfiles (failed to resolve mr-boxington for macos-x64: selecting the packslip artifact for macos-x64). The base mise.lock packslip entry has no darwin x86_64 asset, and mise tries to resolve it for the current platform. --locked (CI) was unaffected, and replacing the alias with disable_tools did not help. This PR uses mise's per-tool os option so one lockfile works on every platform.

What changed

• mr-boxington is limited to linux, macos/arm64, and windows. A "cargo:mbx" entry is limited to macos/x64. Both read {{vars.mbx}} from a single [vars] mbx.
• Deleted mise.macos-x64.toml, mise.macos-x64.lock, .miserc.toml (auto_env), and the [tasks.lock] workaround. Plain mise lock now works everywhere. CONTRIBUTING.md is updated.
• mise.lock gains a version-only cargo:mbx entry and three mr-boxington baseline platform entries.

Scope

Covers the mr-boxington and mbx install and lock flow only. Other tools and CI workflows are unchanged.

Blast radius

Linux CI installs with --locked and MISE_DISABLE_TOOLS=cargo:hk,mr-boxington. cargo:mbx is os-limited to macos/x64, so it is skipped there. Linux, macOS arm64, and Windows were not verified locally.

Verification

mise 2026.11.1 on Intel macOS:

• mise lock, mise install, and mise install --locked all exit 0. Before this change the first two exited 1.
• mise exec -- mbx --version prints mbx 1.29.2, and relocking is a fixed point.
• Changing vars.mbx to 1.29.1 and running mise lock updated both entries and pruned the old ones (reverted afterwards).

Summary by cubic

Fixes Intel macOS mise install and mise lock exiting 1 because mr-boxington ships no darwin x86_64 release asset, and replaces the unrefreshable per-platform lockfile with a single one that works on every platform.

Bug Fixes

• Limits mr-boxington to linux, macos/arm64, and windows; Intel macOS installs the same version from crates.io via cargo:mbx instead.
• Reads both entries from [vars] mbx, so one mise lock refreshes both on version bumps (closes build: keep mise.macos-x64.lock in sync when mr-boxington is bumped #138).
• Removes mise.macos-x64.toml, mise.macos-x64.lock, .miserc.toml, and the [tasks.lock] workaround; updates CONTRIBUTING.md.
