Break the god-class Model in internal/tui/flamegraph/model.go into four
focused sub-controllers that each own a single concern:
- ZoomNavigator : zoom path, stack, root node, and reset/undo logic
- SelectionManager: selected frame index, clamp, traversal, navigation
- FrameAnimator : spring animation, frame layout swap, ancestry index
- SearchController: search query, match indices, filter-visible set
All four are embedded in Model so existing field access (m.selectedIdx,
m.zoomPath, etc.) is promoted unchanged, keeping tests and callers intact.
Model methods now delegate to the sub-controllers rather than holding all
logic inline.
Also split RenderTerminalView (88 lines) into computeRenderParams,
buildToolbar, buildFilteredStatus, and buildNormalStatus helpers, and
extracted buildSnapshotMsg from RefreshFromLiveTrieCmd.
All functions are now ≤ 50 lines. All tests pass.

Move the per-tick snapshot refresh off the Bubble Tea update goroutine,
add a frame ancestry index so navigation and filter helpers run in
O(subtree) instead of O(frames), skip refresh and animation while the
user is actively pressing keys, and memoize View() output. Keystrokes
(pause, filter, navigate) now land within one frame even when the live
trie ingests thousands of events per tick.
- new SnapshotTree() on LiveTrie bypasses JSON marshal+unmarshal
- RefreshFromLiveTrieCmd runs SnapshotTree + layout + ancestry on a
background goroutine, coalesced via refreshInFlight, and returns a
flameSnapshotReadyMsg the Update loop applies cheaply
- driveWindow gate (250 ms after last key press) skips refresh dispatch
and snaps frames directly to target without animation while the user
is driving
- View() caches its rendered string keyed on the inputs that affect
output; cache is bypassed during animation
