The MCP tab had grown into one long scrolling list mixing seven unrelated
areas (File System, Bash Execution, Research Agents, External MCP
Servers, CLI Access, Personal Data, Mail), making it hard to find
anything. Split into a left sidebar (mirroring the existing top-bar
tabButton's blue-accent selected style, just as left-aligned icon+label
rows instead of icon-over-label) with each area now its own standalone
page.
The MCP tab renders outside the shared Settings ScrollView so its
content pane can scroll independently while the sidebar stays pinned —
nesting a plain ScrollView inside another one without an explicit height
just sizes to content rather than scrolling on its own. All 11 other
tabs are unaffected. Bumped the Settings window's min/ideal width
slightly to give the content pane room now that the sidebar takes some
of it on the MCP tab specifically.
Personal Data's and Mail's existing kill-switch guards
(PersonalDataTools/MailTools.isHiddenPendingAppleFix) now also hide
their sidebar rows entirely via MCPSubsection.visibleCases, not just
their content.
