Function canonicalize_tool_name 

pub fn canonicalize_tool_name(name: &str) -> String

Normalise a tool name or alias to its canonical form.

Canonical forms are lowercase and hyphen-free. Accepts common variants:

Input	Canonical
Claude Code, claude-code, claude	claudecode
Cursor, cursor	cursor
Windsurf, windsurf	windsurf
Cline, roo, roo-code, roocode	cline
Gemini CLI, gemini-cli, gemini	gemini
OpenCode, opencode	opencode
Codex, codex	codex

Returns the canonical string unchanged if no alias matches — the caller decides whether unknown names are an error. This function never fails.
