The Context Insights surface moves from a sidebar-foot button opening a
frame-wide overlay to a first-level panel, a sibling of the shipped
Plugins and Automation tasks pages: the page registers on the layout's
keyed `main` slot and the entry on `sidebar.panellist` under one id
(`dsh-context`), so the shell owns the entry row and panel switching —
mounting the page IS opening it (no plugin-side open state, the footer
entry, the overlay seat, and the overviewStore all go away). The
`insightsEntry` preference now mounts/unwinds the registration pair.
Both seats ship on every supported line (0.1.5-rc.1+), pinned per
baseline by the new insightPage seam probe; runtime-verified on a
disposable 0.1.5-rc.1 profile.
The chrome mirrors the shipped first-level pages: one scroll region
with the 960px centered column, the 20px page heading beside the range
group and the balance capsule, and the page element as the `lc-ov`
query container. Inline-size containment makes the page the containing
block for fixed descendants, so the heatmap/usage/balance tooltips can
no longer ride the harness Tooltip (its portal prop is 0.1.7+): they
now carry `data-lc-tip` served by the page's own hover tip — one fixed
bubble portaled to <body>, delegated off the page root (the image
lightbox's precedent), correct on every supported line.
Session card jumps need no close (openSession's own navigation returns
to the conversation); the settings row jump unmounts the page by
selecting the Plugins panel. Verified across 1440-390px in both
locales, and the /context modal is untouched.
