Lithos Dashboard v0.2.2

Bug-fix release: restores Ergo network adoption metrics when the local Ergo
node returns large header or block-transaction responses.

Fixed

Page the rolling 1,000-block header scan using 128-header chainSlice
requests instead of a single oversized lastHeaders/1000 response.
Match the actual Ergo node 6.0.6 chainSlice height boundaries, using
fromHeight=first-1 and toHeight=last and checking for missing or
duplicate canonical heights.
Permit up to 16 MiB for complete block transaction responses only;
retain the original 2 MiB cap for other Lithos and Ergo API requests.
Include the request path in oversized-response errors to speed diagnosis.
Run eight network adoption regression tests in GitHub Actions, including
paging, height-boundary validation, large blocks, and API size limits.

Eight regression tests passed on the development system.
Live Ergo 6.0.6 network adoption scan restored the Ergo network hashrate
and the last-100, last-500, and last-1,000-block adoption statistics.
No changes to mining, NISP commitments, wallet data, or adoption history.
