* feat(tools): add browser delegation tool for corporate web app interaction
Adds BrowserDelegateTool that delegates browser-based tasks to Claude Code
(or other browser-capable CLIs) for interacting with corporate tools
(Teams, Outlook, Jira, Confluence) via browser automation. Includes domain
validation (allow/blocklist), task templates, Chrome profile persistence
for SSO sessions, and timeout management.
* fix: resolve clippy violation in browser delegation tool
* fix(browser-delegate): validate URLs embedded in task text against domain policy
Scan the task text for http(s):// URLs using regex and validate each
against the allow/block domain lists before forwarding to the browser
CLI subprocess. This prevents bypassing domain restrictions by
embedding blocked URLs in the task parameter.
* fix(browser-delegate): constrain URL schemes, gate on runtime, document config
- Add has_shell_access gate so BrowserDelegateTool is only registered on
shell-capable runtimes (skipped with warning on WASM/edge runtimes)
- Add boundary tests for javascript: and data: URL scheme rejection
- URL scheme validation (http/https only) and config docs were already
addressed by a prior commit on this branch
* fix(tools): address CodeRabbit review findings for browser delegation
Remove dead `max_concurrent_tasks` config field and expand doc comments
on the `[browser_delegate]` config section in schema.rs.
