fix: keep CLI prompts visible before upstream config

[cluic]

Summary

• move the default capture path into a SQLite-free module so crp does not import node:sqlite before it needs capture support
• keep interactive crp init and crp start prompts visible when upstream settings are missing
• add CLI regression coverage for check, init, and start startup paths

Testing

• npm test
• manual TTY repro: env HOME="$(mktemp -d -t crp_tty_init)" node node/bin/crp.mjs init
• manual TTY repro: env HOME="$(mktemp -d -t crp_tty_start)" node node/bin/crp.mjs start
