docs: add EVM reference section and sei-js examples

[monty-sei]

Summary

• EVM Compatibility page — replaces matrix.mdx; includes feature support table and unsupported RPC methods (blob methods, pending state, eth_accounts)
• Behavior reference sub-pages — finality, gas & fees, transaction types, state proofs, WebSocket subscriptions, signing (all nested under EVM Compatibility as a dropdown in the sidebar)
• 12 sei-js example pages — viem quickstart, ethers v6 quickstart, wagmi + React, ERC-20, ERC-721, ERC-1155, multicall, pointer contracts, precompile redirect, deploy & verify, transaction lifecycle, error handling (under Ecosystem Tutorials → sei-js Examples)
• @sei-js/registry page — new dedicated docs for CHAIN_IDS, NETWORKS, TOKEN_LIST, GAS_INFO, CHAIN_INFO, WALLETS
• Precompiles example-usage rewrite — viem + ethers CodeGroups throughout; Bank, Staking, Distribution, Governance sections; oracle content removed (retired per sei-infra#1001)
• sei-js examples precompiles page — converted to lightweight redirect pointing to the precompiles section
• Navigation — docs.json updated: EVM Compatibility dropdown under Overview, sei-js Examples group under Ecosystem Tutorials; home page and sei-js index updated with new cards

Test plan

• mint dev builds without errors
• EVM Compatibility page renders with dropdown sub-pages in sidebar
• sei-js Examples group appears under Ecosystem Tutorials
• All internal links resolve (no 404s in preview)
• Precompile example-usage page shows viem and ethers tabs
• sei-precompiles example page redirects cleanly to precompiles section
• @sei-js/registry page appears under sei-js Library in sidebar

PR Summary

Low Risk
Low risk documentation-only change that adds new EVM compatibility/reference pages and example guides; main risk is broken navigation or links in the sidebar/homepage.

Overview
Adds a new EVM Compatibility reference section, including a compatibility matrix plus sub-pages for Sei-specific behavior (finality, gas/fees, transaction types, state proofs, WebSocket, signing) and calls out unsupported RPC methods.

Introduces a sei-js Examples tutorial set (viem/ethers/wagmi quickstarts, ERC-20/721/1155 interactions, multicall, pointer contracts, deploy/verify, transaction lifecycle, error handling) and documents the new @sei-js/registry package.

Reworks evm/precompiles/example-usage to use viem+ethers CodeGroups and updated precompile coverage, and updates navigation (docs.json), evm/sei-js/index.mdx, and the homepage cards to surface the new content.

Retry function silently retries viem contract reverts

Medium Severity

The withRetry function's comment says "Don't retry user rejections or contract reverts," but the guard only catches ethers-style reverts (err?.code === 'CALL_EXCEPTION'). In viem, contract reverts surface as ContractFunctionRevertedError wrapped inside a BaseError — none of the three checks (UserRejectedRequestError, code 4001, code CALL_EXCEPTION) match that. The classifyError utility earlier in the same file demonstrates the correct viem pattern using BaseError.walk(), but withRetry omits it. Developers copying this utility for viem would needlessly retry deterministic failures.
