## Message

```
Indent statements under C/C++ case labels (#60758)

# Objective

Fixes #60261

Nothing under a `case` gets indented in C or C++, and the next `case`
doesn't come back out. It stays flat until you hit `editor: format`.

## Solution

The indent queries had no rule for case labels. Added the same pair
`cpp/indents.scm` uses for `access_specifier`: open an indent range at
the label, close it at the switch's `}`, outdent on the next label.

The part that got me: `@start` uses the *end* of the node you capture.
Fine for `access_specifier`, which is just `public:`. But a
`case_statement` swallows the statements under it, so capturing the node
starts the range after the last one. Capture the `:` instead. `default:`
is a `case_statement` too, so it comes along free.

Only affects what happens after a label, so existing `case` alignment
doesn't move.

## Testing

`test_c_autoindent_switch_case` and `test_cpp_autoindent_switch_case`
cover a plain case, fall-through labels and `default`. Both fail on
main. The `access_specifier` tests still pass.

Not mine, but worth knowing: `typescript::tests::test_outline` and
`test_generator_function_outline` are flaky on main, failing about half
my full `cargo test -p languages --lib` runs with or without this
change.
