cannot use (commits for `c`) or more rows than it accepts (several branches
for `d`) is still the action's own error.

While a target is being picked (`c`, `C`, `f`), the rows the pending command
takes are marked `▸` in the same gutter, outranking `✓`: what the command
takes matters more than what is selected, and `Space` cannot change the
selection anyway. Rows the command names are marked in full; rows a source
only subsumes are marked dim — the files under a `zz` header, and, for `C`,
the `[local changes]` header and the staged files under it, since the index
it commits is named by no row and the header is drawn even closed. The mark is
what keeps the source visible once the cursor moves on to the destination;
the pane title names the same sources (`Commit <sources> → [dest]`,
`Fold <sources> into...`, a count when they do not fit), for the ones
scrolled off. Both go when the mode does.

Add a regression test for both type-change mappings.

The current tests cover regular-file modifications and untracked files only. On Unix, replace a tracked regular file with a symlink and call get_working_changes before staging. Then stage the symlink and call it again. The first assertion covers is_wt_typechange; the second covers is_index_typechange. Reverting either mapping would evade the current tests and return a blank status for that case.

minimal, and validate.

In `@src/core/repo.rs` around lines 1117 - 1136, Add a Unix-only regression test
for the status mappings in get_working_changes: replace a committed regular file
with a symlink, assert the unstaged change reports a worktree modification, then
stage it and assert the change reports an index modification with a clean
worktree. This should fail if either is_wt_typechange or is_index_typechange is
no longer mapped to 'M'.
