the assistant tools fail

Feedback title:
Agent tools broken after latest update — cannot edit any code

Feedback details:
After the latest update, the assistant tools fail, so no code changes can be applied.

1. File read/search tools (Read / Glob / Grep): the request waits about 5 minutes, then is denied with a permission/request timeout.
2. Shell tools (Cmd / PowerShell) and most other tool calls fail immediately with invalid character '{' after top-level value. Any request that contains curly braces { (normal in JSON) breaks. Simple commands without { sometimes work.
3. Sending a message to the user failed with the same { parser error.

Impact: a long session was spent only reading files. No application code was written. Workarounds (avoid {, use read-only Node slice scripts) are not viable for real edits.

Environment: Windows 10, OhMyAgent 686dcb4, permission mode auto, current folder is not a Git repo.

Expected result:
Tools should accept normal requests that contain {, and file read/search should complete in a normal time (not 5 minutes), so code changes can actually be applied.

Reproduce the tool failures on Windows 10 with OhMyAgent 686dcb4, especially requests containing { and the Read/Glob/Grep timeout. Trace the request parsing and tool-dispatch path; done means normal brace-containing requests are accepted and file read/search operations complete without prolonged permission timeouts.
