[codex] clarify first-run picker and npx daemon bin

[philcunliffe]

Summary

Clarifies the first-run picker by adding context under each capture and export option, especially the raw Anthropic/OpenAI API proxy choices.

Adds NPX-aware daemon setup so a real npx hypaware first run installs the current package globally before writing launchd/systemd service files. This avoids pointing the daemon at npm temporary _npx cache paths while keeping explicit --bin, --dry-run, and stable installs unchanged.

Impact

Users get clearer setup choices, and NPX installs now leave behind a durable global hypaware/hyp command for the daemon to execute.
