New types — not yet wired to callers:
- ContextEntry: wraps ConversationEntry with cached token count and
timestamp
- ContextSection: named group of entries with cached token total.
Private entries/tokens, read via entries()/tokens().
Mutation via push(entry), set(index, entry), del(index).
- ContextState: system/identity/journal/conversation sections + working_stack
- ConversationEntry::System variant for system prompt entries
Token counting happens once at push time. Sections maintain their
totals incrementally via push/set/del. No more recomputing from
scratch on every budget check.
Does not compile — callers need updating.

SectionTree:
- 'e': expand all nodes
- 'c': collapse all nodes
- Home/End already wired from previous commit
Key legend shown at bottom border of each focused pane:
- Tree panes: nav, expand/collapse, expand/collapse all, paging
- Agent list: select, tab
- History: scroll, paging
Legend only appears on the focused pane to avoid clutter.

SectionTree.handle_nav() now takes viewport height:
- PgUp/PgDn move both cursor and viewport by one page, keeping the
cursor at the same screen position
- Home/End jump to first/last item
- scroll_to_selected() uses actual viewport height instead of
hardcoded 30
Added render_scrollable() in widgets.rs: renders a Paragraph with a
vertical Scrollbar when content exceeds the viewport. Used by the
conscious and subconscious screens.

New layout for F3 screen:
- Top-left: agent list using ratatui List widget with ListState
- Middle-left: expandable agent state (persistent across runs)
- Bottom-left: memory store activity by provenance, walked keys
- Right: context tree from fork point, reusing SectionTree
Tab/Shift-Tab cycles focus clockwise between panes; focused pane
gets white border. Each pane handles its own input when focused.
Extracted user/widgets.rs:
- SectionTree (moved from mod.rs): expand/collapse tree for ContextSection
- pane_block_focused(): standard bordered block with focus indicator
- format_age()/format_ts_age(): shared duration formatting
