- Deny regex: expand left boundary to match shell separators (;, &&, ||)
to prevent bypass via chained commands like ";format c:"
- Path regex: add "." to initial char class to catch hidden dirs (/.ssh),
add "=" to left boundary to catch flag-attached paths (--file=/etc/passwd)
- Add test: ModelName must match user model for GetModelConfig lookup
- Add test: stripSystemParts preserves reasoning_content in wire format
- Add test: forceCompression avoids orphaning tool result messages
- Add test: deny pattern blocks disk-wiping commands with shell separators
while allowing legitimate --format flags
