Header navigation tabs now appear only when the connected server
advertises the corresponding server capability (from the MCP
`initialize` result `capabilities`), instead of being shown
unconditionally or proxied through list content.
Previously the Tools and Logs tabs were always shown when connected,
regardless of whether the server advertised `tools` / `logging`. The
content-gated tabs (Prompts/Resources/Tasks) only appeared correct
because an unsupported capability yields an empty list — but a server
advertising a capability with a currently-empty list would have its
tab wrongly hidden.
InspectorView.availableTabs now gates each server-capability tab on
the matching field of `initializeResult.capabilities` (already
threaded from App via the handshake):
Tools -> capabilities.tools
Logs -> capabilities.logging
Prompts -> capabilities.prompts
Resources -> capabilities.resources
Tasks -> capabilities.tasks
Apps -> capabilities.tools AND >=1 app tool (Apps is a filtered
view of tools, so it keeps its content check)
Client-side sections are never gated on server capabilities: Servers
and History are always available, and Network stays transport-gated
(hidden for stdio). Tabs recompute live when reconnecting to a server
with a different capability set.
Tests: reworked the content-gating component tests into
capability-gating tests (including the Tools-hidden regression, Logs
present/absent, capability-present-but-empty-list, History-always, and
a reconnect-recomputes test). Connected story/fixtures advertise a
full capability set so the Connected story still shows every tab.
