* fix: prevent document link click from resetting active session
Clicking a #document-<uuid> link in chat caused the session to reset
because of two issues:
1. chatRenderer.js: clicking on the text inside an <a> yields a Text
node target whose .closest() is undefined, so preventDefault never
fires and the browser performs a default hash-navigation
2. sessions.js: the hashchange handler treated the entity hash
(document-<uuid>) as a session lookup, found no match, and the
subsequent loadSessions created a new default-model chat
Fix: walk past Text nodes before calling .closest(), and skip
entity-prefixed hashes in the hashchange handler.

* fix(documents): move isOpen=true after container check in openPanel
isOpen was set to true before the #chat-container existence check.
If the container was missing during a race, the function returned
early but isOpen stayed true, preventing the panel from ever
reopening on subsequent calls.
Move isOpen=true to after the container guard so a failed open
doesn't leave the flag stuck.
