F6 (learn) and F7 (compare) were duplicating the candidate-screen
skeleton: outer magenta-bordered block with screen legend + title,
settings row / content / help vertical split, 40/60 list/detail
horizontal split, j/k/↑/↓ nav with bounds clamping.
Factor out three helpers in user/widgets.rs:
candidate_frame(frame, area, title) -> (settings, content, help)
list_detail_split(content) -> (list, detail)
handle_list_nav(events, list_state, count, on_other)
Callers provide screen-specific content — settings line, empty state,
per-candidate list item, detail pane, help line, extra key bindings —
and the helpers absorb the common framing.
Net change is small in lines (-13 src) but removes the
copy-paste-and-tweak trap: F8/F9/whatever-next-screen now starts from
these three calls instead of a copy of learn.rs.

Move score display from name (via label()) to status column for cleaner
layout. Score now appears right of tokens for all memory nodes.

SectionTree.scroll is now a ScrollPaneState. All callers of
render_scrollable replaced with ScrollPane::render_stateful_widget.
Deleted render_scrollable and its imports — no hand-rolled scroll
rendering remains outside of scroll_pane.rs.

Both had scroll: u16 fields that were never connected to any key
handling or rendering. The unconscious screen renders fixed-size
graph health gauges; thalamus builds a paragraph but never scrolled
it. Neither needs scroll state.

Memory node keys were running into the token count column. Bump the
name column from 40 to 70 characters.

Parser skips Thinking nodes that are just whitespace. Conscious screen
now shows assistant children (Content, Thinking, ToolCall) as nested
tree items via recursive node_to_view. Nodes get timestamped in
push_node and on assistant branch creation.

Add agent/tokenizer.rs with global Qwen 3.5 tokenizer that generates
actual token IDs including chat template wrapping. ContextEntry now
stores token_ids: Vec<u32> instead of tokens: usize — the count is
derived from the length.
ContextEntry::new() tokenizes automatically via the global tokenizer.
ContextSection::push_entry() takes a raw ConversationEntry and
tokenizes it. set_message() re-tokenizes without needing an external
tokenizer parameter.
Token IDs include the full chat template: <|im_start|>role\ncontent
<|im_end|>\n — so concatenating token_ids across entries produces a
ready-to-send prompt for vLLM's /v1/completions endpoint.
The old tiktoken CoreBPE is now unused on Agent (will be removed in
a followup). Token counts are now exact for Qwen 3.5 instead of the
~85-90% approximation from cl100k_base.

Thinking/reasoning content is now a first-class entry type:
- Serialized as {"thinking": "..."} in conversation log
- 0 tokens for budgeting (doesn't count against context window)
- Filtered from assemble_api_messages (not sent back to model)
- Displayed in UI with "thinking: ..." label and expandable content

SectionView gains a status field for extra info displayed after the
token count column. Memory nodes section shows "N scored, M unscored"
in the status column instead of burying it in the title.
Renderer uses fixed-width columns (40 name, 16 tokens, status) for
consistent alignment across sections.

Introduced SectionView {name, tokens, content, children} as a
UI-only tree node, separate from the data ContextSection. The widget
SectionTree renders SectionView with the old recursive expand/collapse
behavior — children for sub-sections, content for text expansion.
section_to_view() converts data sections to UI views, using
ConversationEntry::label() for names and content_text() for
expandable content.
read_context_views() builds the same tree the old context_state_summary
did: System, Identity, Journal, Memory nodes (scored/unscored counts,
expandable to show content), Conversation entries.

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
