Rename CalloutCard to SidebarCallout (it was always sidebar-specific) and
add a shadcn-style Alert primitive with info/success/warning/error variants
for inline use in screens. Replace the misused SidebarCallout in project
settings with Alert and surface the underlying RPC error message instead
of generic copy. Tune destructive color per theme to a calm tinted red.
Adds a Projects settings flow for inspecting and editing per-project
paseo.json (worktree setup/teardown, scripts, terminals) directly from the
app. Reads/writes go through new daemon RPCs with revision-based optimistic
concurrency, and the screen always keeps its header and host picker visible
so a hung host doesn't trap the user.
