refactor: replace ora and inquirer with clack

[nainglinnkhant]

Note

Medium Risk
Broad CLI interaction and error-handling refactor across many commands; behavior should be equivalent but changes in thrown/exit paths and prompt cancellation handling could affect edge cases and scripting output.

Overview
Replaces ora spinners and inquirer prompts throughout the CLI with @clack/prompts, updating user interactions (spinners, confirms, text/select prompts) and standardizing messaging via clack’s log helpers.

Refactors core utilities to throw errors instead of calling process.exit (notably getApiKey, parseOptions, validateMetadata, resolveStore, and manifest parsing), with command handlers catching and exiting; tests and Jest mocks are updated accordingly, and dependencies/lockfile are adjusted (add @clack/prompts, remove ora/inquirer).
