feat: add Solana SDK

[Sabnock01]

Summary

• Adds a full Solana SDK alongside the existing EVM SDK, behind a separate @whetstone-research/doppler-sdk/solana entry point
• Reorganizes the module structure: all EVM code moves to src/evm/, Solana code lives in src/solana/, shared utilities in src/core/
• Inlines Codama-generated TypeScript codecs for all 5 Solana programs directly into src/solana/generated/ — no separate npm package or file: dependency required

What's included

Solana SDK (src/solana/)

• initializer/ — instruction builders and account fetchers for the Initializer program (initialize config/launch, swap, migrate, abort, preview)
• migrators/cpmmMigrator/ — instruction encoders and state fetchers for the CPMM Migrator program
• instructions/ — low-level instruction builders for the CPMM pool (add/remove liquidity, swap, fees, oracle, admin operations)
• client/ — higher-level read clients for config, pool, oracle, and position accounts
• react/ — React hooks (usePool, useSwap, useOracle, usePosition, useLiquidity, useFees) and UI components (SwapCard, LiquidityPanel, PoolStats, PositionCard, ConnectWallet) with wallet and AMM providers

Codama-generated codecs (src/solana/generated/)

• ~160 TypeScript files generated from Anchor IDLs for: cpmm, cpmmMigrator, initializer, predictionMigrator, trustedOracle
• IDL JSON files committed to scripts/idl/; scripts/codegen.ts regenerates from them via pnpm generate:codecs
• codegen.ts patches cpmm/types/index.ts post-generation to resolve a Codama naming collision (AddLiquidityArgs / CollectFeesArgs exported from both event and instruction-args files)
• Marked as linguist-generated in .gitattributes

Module restructure

• src/evm/ — all existing EVM code moved here (no functional changes)
• src/core/ — shared market-cap helpers extracted here
• Four tsup entry points: index, evm/index, solana/index, solana/react/index
• All test and example import paths updated accordingly

CI

• verify-solana-codecs.yml — triggers on IDL/codegen path changes; regenerates codecs and fails if there is a diff, ensuring src/solana/generated/ stays in sync
• test.yml — new Solana Tests job runs pnpm test:solana on every PR; test-summary gate updated to require it

✅ No Address Changes

Compared feat/add-solana-sdk with main

This PR does not modify any addresses currently used by the SDK.

While deployments.generated.ts or addresses.ts may have been updated, the runtime addresses referenced by ADDRESSES remain unchanged. This typically means:

• New contracts were deployed but are not yet integrated into the SDK
• Code formatting or comments were updated
• Unused addresses in the generated file changed
