v2026.4.15

A small release with an important Windows fix and an improved GitHub rate-limit warning. Path-list environment variables now use the correct OS-native separator on Windows, and the 403 rate-limit warning now checks all configured GitHub token sources instead of only the `GITHUB_TOKEN` environment variable.

## Fixed

- **Path-list environment variables broken on Windows** -- Settings that accept colon-separated path lists (`MISE_TRUSTED_CONFIG_PATHS`, `MISE_IGNORED_CONFIG_PATHS`, `MISE_CEILING_PATHS`, `MISE_SHARED_INSTALL_DIRS`, `MISE_TASK_DISABLE_PATHS`) always split on `:`, which conflicts with Windows drive letters (e.g. `C:\foo`). These settings now use the OS-native path separator (`:` on Unix, `;` on Windows) via `std::env::split_paths`, matching how `PATH` itself is handled.

- **GitHub 403 warning shown even when a token is configured** -- The rate-limit warning that appears on GitHub API 403 errors previously only checked the `GITHUB_TOKEN` environment variable. Users who configured a token via `gh` CLI, `github_tokens.toml`, `credential_command`, or `git credential` would still see the misleading "GITHUB_TOKEN is not set" hint. The warning now checks all supported token sources and links to the [GitHub tokens documentation](https://mise.jdx.dev/dev-tools/github-tokens.html).
