* fix(browser): remove hardcoded profile="user" suggestion from browser tool description
The browser tool description hardcoded a suggestion to use profile="user"
for logged-in sessions, even when the operator has configured a different
default profile (e.g. browser.defaultProfile: "openclaw").
Replace with profile-agnostic guidance that references the configured
browser.defaultProfile setting instead of prescribing a specific value.
Fixes#102566
* test: update browser tool description assertion for profile-agnostic wording
* refactor(browser): unify tool profile guidance
