fix(tui): status bar not updating after /verbose, /reasoning, /think commands

The status bar refresh failed because refreshSessionInfo() compared
currentSessionKey (e.g. 'main') against the canonical session keys
returned by the gateway (e.g. 'agent:default:main').

This fix uses parseAgentSessionKey to also match canonical keys by
their 'rest' component, allowing 'main' to match 'agent:default:main'.

Fixes: status bar showing stale values after setting changes
AI-assisted: yes (Claude)
Testing: lightly tested (build passes, logic verified)
