[bug] opencode unhandled tool

[dtger]

When opencode is the harness, the tool calls are showing up as "unhandled tool":

glob (unhandled tool)
grep (unhandled tool)
read (unhandled tool)

This may be due to case mismatch in the way that opencode vs claude code vs other harnesses identify tools, specifically in ToolCallInline.tsx.

• OpenCode likely sends tool names in lowercase: read, edit, bash, grep, glob, write, etc.
• Current getToolDisplay() switch statement parses PascalCase: Read, Edit, Bash, Grep, Glob, Write

Impact

This is largely cosmetic for non-interactive tool calls, but may be easy fix with lowcase() (equivalent, sorry not a typescript guy!) tool names before comparison.
