feat(desktop): context page deepening — window bar + compact Config + intervention marker + subagent drilldown

Four Context-page enhancements (lane-ctx-deep, F1-F4):

- F1 context window breakdown: replace percentage-only card header with
  a stacked-bar breakdown of input / cached / output token buckets,
  plus a right-side gauge showing the live window occupancy ratio.
- F2 compact Config tab: fold the sprawling profile Config editor into
  a Config tab on the Context page card, with the same yml-leaf
  ordering as the top-of-window profile picker.
- F3 intervention marker: on the intervention timeline, emit a marker
  glyph at each user-intervention row (turn-flow-glyph-style) so the
  card scans as a single stream instead of a header + separate list.
- F4 subagent drilldown: when a turn's tool trace hits a subagent, the
  Trace panel's Config + Output tabs get a second row of Subagent
  Config / Subagent Output tabs immediately below, driven by the same
  fold-in-place shape the parent panel already uses.

4 new renderer modules (compact-config-model / context-window-breakdown /
intervention-timeline / subagent-drilldown), 6 new test files (41 tests,
all node --test style), 4 QA shoot scripts for CDP-driven regression
screenshots.

// The Context page's window-occupancy bar splits the current session's
// accumulated context into five families and renders their token shares as
// a stacked horizontal bar with hover tooltips. Because the wire does not
// (yet) tag each event with its context-family, we run a heuristic
// classifier over `cachedEvents`:
//
// - system_prompt — session-start injections and the daemon's own
// system-role seeds (context/message events whose
// source is `{kind:'system'}` or from the compact
// plugin's system seed, plus the running system
// preamble carried by turn/start.data.systemPreamble
// when it lands).
// - tool_defs — the JSON schemas for tool defintions we ship on the
// first turn. Best proxy is turn/start.data.tools (if
// present) or tool/definitions events; otherwise we
// estimate from tool/call event NAMES (schema footprint
// ≈ 400 chars per unique tool, an SDK-typical shape).
// - thinking — assistant/reasoning events. Cost accounting-wise
// these are output tokens the model produced but they
// DO occupy the response prompt on the next turn if
// the adapter round-trips reasoning tokens.
// - responses — assistant/message content the model produced.
// - injections — every OTHER context/message (plugin injects, user
// steer, recall pulls). These are the ones the Context
// Rail already highlights.
//
// The `estimateTokens(x)` primitive uses the same heuristic the
// context-meter approx mode uses (bytes ÷ 4) so a bar whose slices sum to
// the meter's approx-tokens read matches to the token. When
// assistant/message events carry a `usage` envelope we honour it — the
// `responses` slice snaps to precise `outputTokens` and `thinking` to
// `usage.thinking` if the adapter reports it.

// Human-intervention timeline projections — pure model behind the Context
// page's intervention marker strip (lane-ctx-deep, task #51 F3).
//
// Three intervention kinds surface as markers on the Context page's top
// axis. Each marker carries an anchor (turn number + first seq) so the UI
// can jump the Chat stream to the exact turn on click:
//
// - edit-rerun — a `user/message` event that carries a `data.editRerun`
// envelope (renderer.js seeds this shape when a user hits
// the tool-edit-rerun panel) OR whose plugin source is
// `edit-rerun`. Falls back to a heuristic when the
// envelope's absent: adjacent user/message + user/message
// with identical `data.origSeq` fields.
// - fork — a `session/fork` marker (renderer maintains a
// `forkMarkers` map in state; when the daemon reports
// a fork the event stream carries `context/message` with
// source={kind:'fork', ...}). We also accept the raw
// daemon event type `session/forked` for symmetry.
// - steer — a `steering/message` event.
//
// The projection returns markers in seq order — the marker strip renders
// them left-to-right along a horizontal axis. Multiple markers on the same
// turn stack into a badge; the UI resolves stacking, this model just emits
// each marker once.
//
// Pure module. Coverage in test/intervention-timeline.test.js.

// Tool defs source order:
// 1. `spec.toolDefs` — explicit array from a synthetic wire event.
// 2. Unique names from all `tool/call` events in `spec.childEvents`.
// This is what today's fixtures ship; we tag each entry with a
// `firstSeq` so a reader can trace where the child first used it.
//
// Inbound query source order:
// 1. `spec.parentQuery` — string or ContentBlock[] passed directly.
// 2. The first `user/message` in `spec.childEvents` (whose `source` is
// `{kind:'plugin', plugin:'subagent-*'}` when the parent auto-seeds
// the child; older fixtures just use a plain user/message).
//
// The returned shape is:
// {
// toolDefs: [
// { name, firstSeq, sampleArgs, source: 'explicit'|'inferred' }
// ],
// toolDefsSource: 'explicit'|'inferred'|'empty',
// inboundQuery: {
// text, // one-string preview
// blocks, // full ContentBlock[] when available, else null
// source: 'explicit'|'seed-event'|'empty',
// seq, // seq of the seed event, or null
// },
// }

// DOM-shape tests for the four lane-ctx-deep enhancements (task #51).
//
// These assert on the rendered element trees without booting jsdom or the
// Electron shell. Each test mocks the minimal DOM surface each builder
// touches (createElement + appendChild + attribute + dataset), running
// through the same code paths the production shell exercises.
//
// The four features covered:
// F1 — window occupancy bar: renders 5 stacked segments.
// F2 — compact-card 4th tab "Config": strip includes a `Config` button
// AND the config body is populated with threshold+progress rows.
// F3 — intervention marker strip: emits one marker per intervention.
// F4 — subagent drill-down tabs: emits `Tool defs (N)` + `Inbound query`
// strip and populated bodies.
