ref-based get commands break across normal CLI invocations in direct CDP mode

[ox01024]

Summary

In direct CDP mode, ref-based get commands are unreliable across normal CLI invocations.

Reproduction

Using the normal standalone CLI flow:

node dist/cli.js tab 3 --json
node dist/cli.js snapshot --json
node dist/cli.js get text 0 --json
node dist/cli.js get url --json
node dist/cli.js get title --json

Observed before fix:

• the second process often fell back to the wrong tab (about:blank) because the selected target was only stored in-process
• get text <ref> could fail with Unknown ref or return an empty string
• get url / get title failed with Missing ref or attribute parameter

Root Cause

packages/cli/src/cdp-client.ts only tracked currentTargetId in memory, so a fresh CLI process lost the selected tab. On top of that:

• get text tried to resolve text through a non-existent [data-bb-node-id=...] selector
• get url / get title incorrectly required ref

Expected

Normal multi-invocation CLI usage should keep operating on the selected target, and get text|url|title should return the expected values without requiring a fresh snapshot or a bogus ref.
