Ryan Walker 85af3c7e43 editor: Fix folding for unindented multiline strings and comments (#50049)
Closes #5057

## Summary

The indent-based code fold detection does not account for lines inside
multiline strings or block comments that have less indentation than the
surrounding code. This causes the fold scanner to think the enclosing
block ends prematurely.

For example, folding `fn main()` here would fail because the raw string
content at indent level 0 gets treated as the end of the function body:

``` rust
fn main() {
    let s = r#"
unindented content
"#;
}  
```

This PR checks whether a low-indent line falls inside a string or
comment override region and skips it if so. This works across all
languages that define `@string` or `@comment` overrides in their
`overrides.scm`.

## After


https://github.com/user-attachments/assets/cd5b36db-6d4d-420b-9d60-79f9fad8638e

## Test Plan

- Added `test_fold_with_unindented_multiline_raw_string`
- Added `test_fold_with_unindented_multiline_block_comment`
- All existing fold tests pass
- Manually tested both Rust and Python examples

Release Notes:

- Fixed code folding incorrectly collapsing when multiline strings or
block comments contained unindented content

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.

Sponsorship

Zed is developed by Zed Industries, Inc., a for-profit company.

If you’d like to financially support the project, you can do so via GitHub Sponsors. Sponsorships go directly to Zed Industries and are used as general company revenue. There are no perks or entitlements associated with sponsorship.
