Remove obsolete historical scripts and artifacts

[clement-ux]

Plain-English summary

This repository still contains many files from workflows that are no longer used: old staking and liquidity scripts, generated diagrams, unused ABIs, copied libraries, and empty placeholders.

This PR removes only that historical baggage. It does not replace Hardhat or change how active commands and local forks run. Keeping this cleanup separate makes the three functional migration steps much easier to review.

Context

Foundry already handles contract compilation, testing, deployment, and ABI generation. Hardhat remains temporarily for two active jobs:

1. running operational commands;
2. running the local/forked node.

The next three PRs replace those jobs one at a time, then remove Hardhat.

What changes in this PR

• remove retired Resolution, staking, compensation, and liquidity scripts;
• remove obsolete Hardhat-only ABIs and the historical localhost.json snapshot;
• remove orphaned diagrams and their generator entries;
• remove unused Rooster library copies and stale analysis configuration;
• remove empty test/deployment placeholders and dead utility modules;
• remove documentation and package-script references to those deleted files.

What does not change yet

• active operational commands still run through Hardhat;
• Hardhat still provides the local/forked node;
• no runtime replacement happens in this layer.

What to review

The important question is not the implementation of a new runtime; there is none here. Please check that every deleted category is genuinely retired and that no surviving file still points to a deleted path.

This layer changes 80 files: 24,782 deletions and 8 small documentation/configuration additions.
