leeguooooo 284a60a54c feat(adopt): read a pre-existing tab without opening a new one ...

New `chrome-use adopt <url-substring|targetId>`: drive a tab the user (or
another session) already has open, with ZERO new tabs. After group-scoped
isolation (#40) a session can't see foreign tabs, so adopt adds an explicit,
opt-in path:

- Relay (relay.rs): `ABRelay.getAllTargets` returns every attached target
  UNSCOPED (ignores group scoping), so the agent can find a specific tab by URL
  or targetId. +1 unit test.
- Daemon (browser.rs): `collect_all_targets` (unscoped, falls back to scoped on
  older relays) + `adopt_existing_target` — matches by exact targetId or
  case-insensitive URL substring, attaches it (the relay re-tags it into the
  adopter's group, so isolation holds), pins it; never creates a tab. On no
  match it errors AND lists the open tabs it can see, rather than launching.
  discover_and_attach_targets honors AGENT_BROWSER_ADOPT at first connect, so no
  about:blank is ever created.
- CLI (main.rs): `adopt` sets the env, forces a fresh daemon, and rewrites into
  `connect <relay-url>` (like `extension connect`) so the daemon attaches to the
  user's real Chrome before parse_command.

Extension (ab-connect 0.4.11): `reannounceAttachedTabs` now re-sends each tab's
url/title (it previously sent neither) so the relay's target list stays matchable
by URL after the MV3 service worker reconnects — otherwise reannounced tabs show
a blank url and `adopt <url>` can't find them. Repacked upload zip + crx.

Mechanism verified live (enumerated all 11 of the user's open tabs incl. the
target). 862 tests pass.
