Zed logs "reading bytes of the file" errors for directories sent as ToolCallLocation #33510

Running opencode under Zed, I see this in ~/.local/share/zed/logs/Zed.log after every bash/grep/glob call:

ERROR [crates/acp_thread/src/acp_thread.rs:646] reading bytes of the file "/home/bryan/github/bcdady/opencode"

The path is my project root, not a file. Looks like packages/opencode/src/acp/tool.ts toLocations returns [{ path: workdir }] for bash/shell and locationFrom(input.path) for grep/glob - those are directories, and Zed tries to read them as files.

Tool calls still work, just noisy logs.

I'll follow up with a PR that drops the bash workdir location (it's already in rawInput.cwd) and filters non-files out of the grep/glob path.
