#4109: fix(cli): bypass config guard for tui --url

Fixes #3107. Summary: - Treat `moltbot tui --url ...` as client-only mode. - Bypass config validation in the CLI preAction hook so a remote TUI client doesn’t require local plugins/config. Testing: - pnpm lint - pnpm build - pnpm test AI-assisted: yes (Codex CLI). Docker: not available locally for `docker run ...` smoke checks. <!-- greptile_comment --> <h2>Greptile Overview</h2> <h3>Greptile Summary</h3> This PR updates the CLI preAction hook so `moltbot tui --url …` is treated as a client-only mode and skips `ensureConfigReady`, allowing remote TUI usage without requiring local config/plugins. It also documents the behavior in `docs/cli/tui.md` and adds a focused Vitest to ensure the config guard is bypassed when `--url` is provided and still enforced otherwise. <h3>Confidence Score: 4/5</h3> - This PR is likely safe to merge; changes are small and covered by a targeted unit test. - The change is localized to the CLI preAction hook and gated on `tui` + `--url`, with a new test asserting both bypass and non-bypass paths. Main remaining risk is edge-case argv ordering/flag forms not covered by tests, and the new test’s reliance on global `process.argv` state. - src/cli/program/preaction.ts; src/cli/program/preaction.tui-remote-bypass.test.ts <!-- greptile_other_comments_section --> _{(4/5) You can add custom instructions or style guidelines for the agent [here](https://app.greptile.com/review/github)!} <details><summary><h4>Context used (3)</h4></summary> - Context from `dashboard` - docs/cli/agents.md ([source](https://app.greptile.com/review/custom-context?memory=057a11aa-5c5f-48bb-8d53-91b27b0fe3a2)) - Context from `dashboard` - CLAUDE.md ([source](https://app.greptile.com/review/custom-context?memory=fd949e91-5c3a-4ab5-90a1-cbe184fd6ce8)) - Context from `dashboard` - AGENTS.md ([source](https://app.greptile.com/review/custom-context?memory=0d0c8278-ef8e-4d6c-ab21-f5527e322f13)) </details> <!-- /greptile_comment -->
