Add comprehensive tests for Solana and asset management functionality

[Corey-Code]

This pull request adds first-class support for SVM (Solana Virtual Machine) networks and assets to the codebase, alongside existing Cosmos, Bitcoin, and EVM support. The changes include Solana key derivation, network and asset registry integration, account management in the keyring, and static asset definitions. Additionally, several EVM networks and their native assets have been added to improve coverage.

Key changes:

Solana/SVM Support:

• Introduced Solana (SVM) key derivation and address utilities in the new src/lib/crypto/solana.ts, supporting BIP44 derivation, base58 encoding, and address validation.
• Extended the Keyring class to support SVM accounts, including methods for deriving, retrieving, serializing, and restoring Solana accounts, and updated serialization logic to handle SVM data. [1] [2] [3] [4] [5] [6]
• Added SVM network and asset definitions, including static assets for Solana mainnet, devnet, testnet, and Eclipse, and integrated SVM asset support into asset fetching and fallbacks. [1] [2] [3] [4]
• Updated network registry and type-checking utilities to recognize SVM networks, with new helpers and exports for SVM network configs. [1] [2] [3] [4] [5] [6]

EVM Network and Asset Expansion:

• Added native asset definitions for multiple EVM networks, including eth-mainnet, pol-mainnet (Polygon), arb1-mainnet (Arbitrum), oeth-mainnet (Optimism), cro-mainnet (Cronos), ftm-mainnet (Fantom), gno-mainnet (Gnosis), manta-mainnet, zksync-mainnet, metis-andromeda-mainnet, and zkevm-mainnet. [1] [2] [3]
• Updated token color mappings for new EVM and SVM assets.

Dependency Update:

• Added @noble/curves as a dependency to support Ed25519 cryptography for Solana key derivation.

Pull request overview

This PR introduces first-class Solana/SVM support and significantly expands network and asset handling across the wallet, including cryptography, network registry, keyring, storage, UI, and documentation, along with comprehensive tests. It also adds a static known-asset registry for popular ERC20 and SPL tokens and extends native asset definitions for multiple EVM networks.

Changes:

• Add Solana/SVM cryptography (Ed25519 SLIP-0010 derivation), RPC client, network configs, and keyring support, plus wallet store and UI wiring for SVM accounts and addresses.
• Extend the asset system with static native assets for many EVM and SVM networks and a large known-token registry (ERC20 & SPL), integrating into the Network Manager and Dashboard.
• Update storage, network abstractions, and documentation to support the new network type pattern, and add targeted tests for Solana crypto/client, network registry SVM handling, and asset registries.

File	Description
tests/lib/solana/client.test.ts	New test suite covering SolanaClient RPC behavior (balances, token balances, slots, blockhash, rent exemption, tx send, signature status, account info, RPC error handling).
tests/lib/networks/registry.test.ts	Extends registry tests to cover SVM networks (Solana mainnet/devnet configs, SVM type guards, enabled SVM networks, explorer URL helpers).
tests/lib/crypto/solana.test.ts	New tests validating Solana derivation paths, deterministic Ed25519 key derivation from mnemonics, address formatting, and basic address validation behavior.
tests/lib/assets/knownAssets.test.ts	New tests for the known ERC20/SPL token registry; currently assert that getKnownErc20Tokens(56) and (137) return [], which conflicts with the new BSC/Polygon token lists and will need updating.
src/store/walletStore.ts	Extends pre-derivation and account-creation/import flows to derive and persist SVM addresses, adds getSvmAddress/deriveSvmAccount store methods, and changes Bitcoin/EVM pre-derivation to cover all networks (not just enabled) for better future enablement behavior.
src/store/networkStore.ts	Broadens getNetworksByType to include the new 'svm' NetworkType so UI and logic can retrieve SVM networks via the store.
src/popup/pages/Dashboard.tsx	Integrates SVM into the Dashboard: adds SVM tab, SVM address derivation and caching (per account/network), ensures balances only load once SVM addresses are derived, and adjusts network list styling and account menu layout.
src/popup/pages/CreateWallet.tsx	Adjusts the root container to allow horizontal overflow and fit-content width, improving layout behavior for the create-wallet flow.
src/popup/components/NetworkManagerModal.tsx	Extends Network Manager with an SVM tab, type-aware asset loading for Cosmos/EVM/SVM (including known ERC20/SPL tokens), and updated badge color schemes for the new network type.
src/lib/storage/encrypted-storage.ts	Adds an svm map to the derivedAddresses structure for imported accounts and threads it through add/get/update helpers so SVM pre-derived addresses are stored and retrievable without passwords.
src/lib/solana/index.ts	New Solana module barrel exporting the SolanaClient, factory, and related types.
src/lib/solana/client.ts	New Solana RPC client implementing JSON-RPC calls for SOL balances, SPL token balances, slots, blockhashes, rent, sending transactions, signature status, account info, and RPC URL failover.
src/lib/networks/types.ts	Introduces SvmNetworkConfig and extends NetworkType/NetworkConfig unions, modeling core SVM properties (rpcUrls, cluster, isMainnet).
src/lib/networks/solana.ts	Adds concrete SVM network configs for Solana mainnet/devnet/testnet and Eclipse mainnet, plus helpers to list and filter enabled SVM networks.
src/lib/networks/registry.ts	Registers SVM networks, adds getSvm, isSvmNetwork, and ensures explorer URL helpers work for the new networks in addition to existing types.
src/lib/networks/index.ts	Re-exports SVM config types, concrete SVM networks, SVM registry helpers, and SVM type guard alongside existing network exports.
src/lib/crypto/solana.ts	New Ed25519 SLIP-0010 key-derivation module for Solana, including BIP44 path generation, mnemonic-to-keypair derivation, base58 address encoding, and a lightweight isValidSolanaAddress check.
src/lib/crypto/keyring.ts	Extends the Keyring with an SvmKeyringAccount type, in-memory SVM account storage, derivation from the main mnemonic, serialization/deserialization of SVM addresses for session persistence, and SVM key getters that can re-derive keys when needed.
src/lib/cosmos/chains.ts	Updates getNetworkType to return 'svm' for SVM networks, enabling generic network-type routing logic to recognize SVM.
src/lib/assets/knownAssets.ts	Introduces a comprehensive static registry of known ERC20 tokens across many EVM chains and SPL tokens on Solana mainnet, with helpers to retrieve token lists, look up tokens by denom, and extract contract/mint addresses.
src/lib/assets/chainRegistry.ts	Adds static native asset definitions for a wide set of EVM networks and SVM networks, integrates them into fallback assets, and updates fetchChainAssets and token color mappings to handle EVM and SVM types.
package.json	Adds @noble/curves as a dependency for Ed25519 functionality and keeps existing cryptographic dependencies aligned with the new SVM crypto module.
package-lock.json	Locks in @noble/curves and its transitive @noble/hashes dependency (v2.x) alongside the existing hashes dependency, matching the new crypto usage.
docs/ADDING_NETWORK_TYPE.md	New, thorough guide documenting all steps required to add a new network type (patterned after the SVM integration), spanning types, networks, crypto, keyring, storage, UI, and testing.
