I added navigation for file:line:col hover links e.g. `file.rs:83`,
similar to what the cli and terminal already do. I also added backticks
as file delimiters so that you can open file paths in markdown
documents, see:

Btw the Zed docs don't mention this yet, but on native ARM64 Windows the
build fails with `error: instruction requires: fullfp16` from the
`gemm-f16` crate. I fixed this by adding `+fp16` to the target feature
flags:

```toml
[target.'cfg(target_os = "windows")']
rustflags = [
    "--cfg", "windows_slim_errors",
    "-C", "target-feature=+crt-static,+fp16",
]
```

CI cross-compiles from x86_64 so it doesn't hit this.
