DeltaQ report

Signed-off-by: Chris Gianelloni <[email protected]>

Maps adversarial relay node infrastructure costs to measurable
front-running rates, with exploitable yield discounted by FIFO
batcher prevalence and DEX order fraction from script mapping.

Move ChainTree, ChainNode, and their 7 unit tests from consensus.rs
into chain_tree.rs. Add point() accessor so consensus doesn't reach
into ChainTree internals.

Display tip_hash alongside tip_block_no in the inspector panel,
matching the format already used in topology nodes (e.g. "5 #a3b2").

Emit NodeEvent::RolledBack for both peer-triggered rollbacks
(NetworkEvent::RolledBack) and consensus fork-switch rollbacks
(on_validation_complete returns true). UI shows violet flash on
topology nodes and magenta chip in event log.

Track adopted_tip_hash separately from the chain tree's speculative
best tip. When on_validation_complete finds the new block is on a
different fork than the adopted tip, walk prev_hash links to find
the common ancestor and issue InjectRollback before InjectBlock.

Replace the single local_tip in Consensus with a ChainTree that tracks
block headers keyed by hash, linked via prev_hash. Longest chain
(highest block_number) is selected as best tip. Blocks deeper than
security_param_k (default 2160) are pruned.

Block production now receives prev_hash and block_number from consensus
so headers contain correct chain linkage and globally consistent height.

Use Typography component="div" so the Chip (renders <div>) isn't
nested inside a <p> element.

Track blocks_produced in NodeSeriesPoint and display a green blocks
chart in the inspector, matching the aggregate charts style.

Style recharts tooltips in aggregate charts and inspector panel with
dark backgrounds and white text to match the dashboard theme.

Dark purple background, larger title left-aligned, node/edge count
on the right, white text throughout.

Replace 1s HTTP polling with Server-Sent Events for event delivery.
Events now appear in the UI as they arrive from nodes, making block
propagation visible as a wave across the graph.

- Add GET /api/events/stream SSE endpoint with broadcast channel
- Add useEventStream hook with 50ms batching to avoid render storms
- Remove TipAdvanced from flash triggers (redundant with RBReceived)
- Protect "produced" flash from being overwritten by "received"
