…i CLI, and OpenCode Add detection for four new AI coding agents that were missing compared to similar tooling (e.g. Stripe CLI). Also add CURSOR_AGENT as a fallback env var for Cursor detection alongside the existing CURSOR_TRACE_ID. New operators and their env vars: - Cline: CLINE_ACTIVE - Codex CLI: CODEX_SANDBOX, CODEX_THREAD_ID - Gemini CLI: GEMINI_CLI - OpenCode: OPENCODE - Cursor (additional): CURSOR_AGENT
Cline (and potentially other future agents) are VS Code extensions, so TERM_PROGRAM=vscode is always set when they're active. The previous ordering would misclassify Cline as 'vscode' (interactive) instead of 'cline' (agent). Moving the VS Code check after all agent-specific checks ensures extensions are correctly detected as agents.

Expands operator detection to cover AI coding agents we were missing compared to similar CLIs

Compared our detection with other CLIs. Other CLIs covered 7 agents; we covered 5. This PR closes the gap and adds a second env var for Cursor (Stripe uses
CURSOR_AGENT, we usedCURSOR_TRACE_ID— now we check both).Test plan
