Fixes#48231
## Problem
When debugging Rust programs with CodeLLDB, panic breakpoints ("Rust: on
panic") don't work unless `sourceLanguages: ["rust"]` is explicitly set
in the debug configuration.
Without this setting, CodeLLDB doesn't return the `rust_panic` exception
filter, so the breakpoint shows `locations = 0 (pending)` and never
triggers.
## Root Cause
The Cargo locator correctly adds `sourceLanguages: ["rust"]`
([cargo.rs:97-100](https://github.com/zed-industries/zed/blob/main/crates/project/src/debugger/locators/cargo.rs#L97-L100)),
but other code paths may not:
- VSCode launch.json imports
- Manual debug configurations
## Solution
Auto-detect Rust binaries in `CodeLldbDebugAdapter::get_binary()` by
checking if the program path contains `/target/debug/` or
`/target/release/` (Cargo's standard output directories).
If detected and `sourceLanguages` isn't already set, we automatically
add `["rust"]`.
Release Notes:
- Fixed Rust panic breakpoints not working in debugger when using
CodeLLDB with non-Cargo debug configurations
