Granular Indentation Control for Specific Method Patterns (e.g., Stream.of())

[config (3).txt](https://github.com/user-attachments/files/19683938/config.3.txt)

Using the Eclipse formatter (via Spotless), we're currently limited by the global nature of the continuation_indentation setting. This results in undesired formatting when using chained methods like:

```
var stream = Stream.of(

[config (3).txt](https://github.com/user-attachments/files/19683922/config.3.txt)

item1,
item2
)
.flatMap(Collection::stream);
```
We'd like to customize indentation specifically for Stream.of() or similar method patterns to produce the following:

```
var stream = Stream.of(
// Desired: 8 spaces for arguments inside Stream.of()
item1,
item2
)
.flatMap(Collection::stream);
```
Problem

- continuation_indentation affects all method chains, so it's impossible to tune just one specific case.
-
- Formatting gets harder to read when method chains are involved, especially for deeply nested calls.
-
- We'd like more flexibility — such as per-method or per-pattern indentation control.

Request
Introduce a way to:

- Apply custom indentation levels based on method name or type.
-
- Optionally override continuation_indentation when a method is in a known list (like Stream.of, List.of, etc.)

Notes
We're using Eclipse formatter via Spotless, which just forwards to this engine. They've redirected us here for this enhancement.
