feat(tui): full/compact view modes for the session list#939
Merged
Conversation
The session list gains a two-line full-card view alongside the existing one-line compact rows, mirroring the lineage section's full/compact pair: - Full mode adds a muted detail line under each session name: model and reasoning effort, a four-cell context-window gauge with percentage, activity (live busy time while running, coarse age otherwise), lifetime token volume, and cost. Segments drop least-important-first on narrow sidebars; sessions reporting no usage data fall back to their directory. - Toggled by a clickable label on the pane's top border next to the ' + sessions ' title, with a hover tooltip; the choice persists across launches (tui-state.json, legacy blobs restore to compact). - Display rows and items are no longer 1:1, so the renderer records a row-to-item map used by click and diamond-hover hit-testing; gutter affordances (disclosure, pin) stay on a card's first line. Scroll limits, scrollbar geometry, and harness hover zones are measured in display rows. - Spec 0106 records the design decision.
…utton
Matches the lineage header's layout: ' compact \u{21c4} ' / ' full \u{21c4} '
sits immediately left of the ' \u{ab} ' collapse control instead of next to
the ' + sessions ' title.
Program feedback on the full session-list view: - The dollar amount no longer renders on the detail line (spec 0106 updated: cost is deliberately excluded). - The four-cell context gauge now rounds its fill to the nearest quarter instead of ceiling, so 54% reads as two cells rather than three.

Summary
Adds a full/compact view-mode pair to the session list, mirroring the lineage section's precedent (spec 0106 records the decision):
busy 4m12swhile running, coarse2h agootherwise), and lifetime tokens (cost is deliberately excluded). The gauge's fill rounds to the nearest quarter so the bar tracks the percentage. Absent data is omitted; sessions reporting nothing (plain shells) fall back to their directory. On narrow sidebars, segments drop least-important-first (tokens → activity → model → gauge) instead of wrapping.compact ⇄/full ⇄label on the pane's top border, right-aligned immediately before the«collapse button — the same placement and label shape as the lineage header's toggle — with hover styling and a tooltip. The choice persists intui-state.json(legacy blobs restore to compact).LayoutSnapshot::list_visible_rows) used by click and pin-diamond-hover hit-testing; disclosure/pin gutters live on a card's first line only, while a click anywhere in the card selects it. Scroll clamping (App::list_max_scroll), scrollbar geometry, and harness hover zones are measured in display rows, so mixed-height items (one-line group headers among two-line cards) stay correct. As a side effect, diamond-hover now honors the scroll offset through the same map the click path uses.compact (unchanged, default)
