clangd crash on stdexec project

I added stdexec to my project and clangd starts crashing if it goes through its symbols.

I figured out how to reproduce it without any of my code.
1. Clone stdexec repo https://github.com/NVIDIA/stdexec
2. Configure it with CMake. It has a clangd helper witch automatically add CMAKE_EXPORT_COMPILE_COMMANDS and create symlink to compile_commands.json into repo root directory. Ensure it is. It also provides .clangd config file.
3. Open project in editor with clangd. I'm using Zed with the following options
```json
"lsp": {
"clangd": {
"binary": {
"arguments": [
"--header-insertion=never",
"--query-driver=**"
]
}
}
}
```
But it looks like it does not depend on my options.
4. Open one of the files e.g `examples/hello_coro.cpp`
5. Try to modify the file and format it with cland's clang-format.
6. After a few seconds clangd is crashed with logs:

It crushes with different logs but it's always
`Signalled during AST worker action:`

```sh
clangd --version
clangd version 22.1.1
Features: linux
Platform: x86_64-pc-linux-gnu
```
```sh
zeditor --version
Zed 0.227.1 – /usr/lib/zed/zed-editor
```

Reproduce the crash by configuring stdexec with CMake, opening examples/hello_coro.cpp in clangd, and formatting after an edit. Start with the stack trace around StmtProfile.cpp and ASTReader serialization paths, especially ConceptSpecializationExpr and readFunctionProtoType. Done means clangd remains running during this workflow and no crash report is produced.
