chore: remove deprecated settings older than 12 months

[jdx]

Summary

• Remove 14 deprecated setting aliases that have had replacements for 18+ months (since Sep-Nov 2024)
• Settings removed: asdf, cargo_binstall, disable_default_shorthands, npm.bun, pipx_uvx, python_compile, python_default_packages_file, python_patch_url, python_patches_directory, python_precompiled_arch, python_precompiled_os, python_pyenv_repo, python_venv_stdlib, vfox
• Removes associated migration code in settings.rs and legacy e2e tests
• asdf_compat and profile are kept (still has active code usage / env var fallback)

Test plan

• cargo build compiles cleanly
• mise run lint passes
• Schema regenerated
• CI passes

Note

Medium Risk
Removes multiple long-deprecated settings and their migration code, which can break existing configs or env var usage that still relies on the old names. Changes are otherwise straightforward and largely limited to config/schema/docs and e2e coverage.

Overview
Drops support for multiple deprecated settings/aliases (e.g. asdf, vfox, cargo_binstall, disable_default_shorthands, legacy python/pipx aliases) by removing them from the generated settings.toml/schema/mise.json and deleting their migration wiring in src/config/settings.rs.

Updates docs and e2e coverage to reflect the supported replacements, notably standardizing npm tests on MISE_NPM_PACKAGE_MANAGER and documenting disable_default_registry in docs/configuration.md.

Greptile Summary

Removes 13 long-deprecated settings (asdf, cargo_binstall, disable_default_shorthands, pipx_uvx, and 9 python_* flat-name aliases) from settings.toml, schema/mise.json, and their migration logic in settings.rs, along with related e2e coverage. Note that npm.bun is listed in the PR description as removed but remains defined in settings.toml/schema/mise.json and its migration code (if self.npm.bun { ... }) is intentionally kept — only its e2e tests were removed.

Confidence Score: 5/5

Safe to merge — removing 18+-month-old deprecated aliases with no P0/P1 findings

All canonical replacement settings preserve the same environment variable names (MISE_CARGO_BINSTALL, MISE_PIPX_UVX, MISE_PYTHON_COMPILE, etc.), so no user-facing env var breaks occur. The only finding is a cosmetic P2 leftover unset line in a test file.

e2e/backend/test_npm_package_manager has a leftover unset MISE_NPM_BUN on line 30 that can be cleaned up

Important Files Changed

Filename	Overview
src/config/settings.rs	Removes migration blocks for 13 deprecated settings; intentional npm.bun handling retained
settings.toml	Drops 13 deprecated flat-name settings; npm.bun kept as still-deprecated (hidden) alias
schema/mise.json	Schema entries for all 13 removed deprecated settings deleted cleanly
e2e/backend/test_npm_package_manager	Legacy npm.bun tests removed; leftover unset MISE_NPM_BUN on line 30 is dead code
e2e/backend/test_backend_missing_deps	Correctly replaces MISE_NPM_BUN=true with MISE_NPM_PACKAGE_MANAGER=bun
docs/configuration.md	Updates example to use disable_default_registry instead of removed disable_default_shorthands

Code Review

This pull request removes a significant number of deprecated configuration settings from the mise codebase, including asdf, cargo_binstall, disable_default_shorthands, npm.bun, pipx_uvx, and multiple python-specific options. The changes span documentation, the JSON schema, settings.toml, and the internal Rust configuration logic, effectively cleaning up legacy code and tests. I have no feedback to provide.

If it's intended sorry, but npm.bun is deprecated in last December, not that old.
