Fixes #14775

With `MISE_OVERRIDE_TOOL_VERSIONS_FILENAMES=.combined-tool-versions`, commands that load tracked configs (`mise ls --prunable`, `mise prune`, `mise upgrade`) warned `unknown config file type` for every tracked `.tool-versions`, and skipped them, so `mise prune` could treat those projects' versions as unused.

Tracked files now fall back to recognizing the builtin `.tool-versions` name regardless of the override, so they load without warnings and their versions stay protected.

MISE_OVERRIDE_TOOL_VERSIONS_FILENAMES=.combined-tool-versions mise prune --dry-run

Added e2e test `test_prune_tracked_tool_versions_override`.

Note

Low Risk
Narrow change to tracked-config type detection when a filename override is active; reduces incorrect prune behavior without touching auth or global config resolution.

Overview
When MISE_OVERRIDE_TOOL_VERSIONS_FILENAMES is set, tracked .tool-versions paths were no longer classified during load_tracked_config_files, which produced unknown config file type warnings and let mise prune (and similar commands) treat those projects’ pinned versions as unused.

Tracked config loading now falls back to ToolVersions for paths whose basename is .tool-versions, even if the override hides that name from normal filename detection, so tracked pins stay loaded and protected.

An e2e script asserts mise prune --dry-run under the override emits no tracked-config errors and only prunes versions not referenced by the tracked file.

Summary by CodeRabbit

• Bug Fixes
  • Fixed an issue where mise prune --dry-run could incorrectly report tracked .tool-versions files as unknown when filename overrides were active.
  • Protected versions referenced by tracked configuration are now correctly recognized and excluded from pruning.
  • Dry-run output no longer includes erroneous tracked-configuration or unknown-file errors in this scenario.
  • Untracked tool versions remain correctly identified as eligible for pruning.

📝 Walkthrough

Tracked config loading now recognizes .tool-versions files when filename detection returns no type. An end-to-end test checks that mise prune --dry-run does not report config errors or prune a tracked version when a temporary filename override is active.

Changes: Tracked config recognition

Layer / File(s)	Summary
Tracked file fallback and prune validation src/config/mod.rs, e2e/cli/test_prune_tracked_tool_versions_override	Tracked .tool-versions files fall back to ToolVersions when filename detection returns no type. The end-to-end test checks for config errors, retains tracked dummy@2.0.0, and reports untracked dummy@3.0.0 for pruning.

Full details: Linked Issues check

Explanation

The pull request satisfies active issue #14775. src/config/mod.rs classifies a tracked file with basename .tool-versions as ConfigFileType::ToolVersions when the filename override prevents normal detection. This removes the unknown-file warning and preserves tracked versions for pruning. The added e2e/cli/test_prune_tracked_tool_versions_override test verifies no warning, protection of dummy@2.0.0, and pruning of untracked dummy@3.0.0.

Add a positive prune assertion.

The current negative assertions pass if mise prune --dry-run produces no output. Assert that the installed but unreferenced dummy@3.0.0 version is reported by the same command.
