/**
 * toolCallSummary — compute a compact one-line summary of a tool invocation's
 * args, matched to what Claude Code puts inside the parenthesis of its
 * terminal header (`Read(src/foo.ts)`, `Bash(npm test)`, etc.).
 *
 * This is the *identity* of a tool call at a glance — the tool name alone is
 * not enough to distinguish three Reads in a row. Rendering this next to the
 * name in the collapsed card header is what makes a trace scannable without
 * expanding every entry.
 *
 * Kept as a pure string helper (not a component) so:
 *   - live event handlers + session-JSONL replay call it identically,
 *     guaranteeing the same header text in both flows.
 *   - consumers outside React (trace archive, MCP, tests) can reuse it.
 *
 * Unknown tool names return `''` — the card renders just the tool name then.
