Walkthrough

Repository-wide updates include Node.js/runtime version bumps, dependency upgrades, and multiple network registry changes (additions/removals/renames). A new private-key export flow is added end-to-end (UI → background → keyring). Name-resolution disables SID paths. Tests/settings updated accordingly.

Types: network enum updates packages/types/src/networks.ts	NetworkNames changes: add TAC; replace ZkSyncGoerli → zkSyncSepolia; remove SkaleChaos, Opal, Form(FormTestnet), CagaAnkara; rename CotiDevnet → CotiTestnet.
Etherscan endpoints packages/extension/src/providers/ethereum/libs/activity-handlers/providers/etherscan/configs.ts	Removed SkaleChaos, ZkSyncGoerli, Form(FormTestnet) endpoints; added TAC endpoint.
Assets handler (MEW) packages/extension/src/providers/ethereum/libs/assets-handlers/assetinfo-mew.ts	For Sanko, set bsEndpoint: true and clear tbName, switching to Blockscout balances.
Common new-features flag packages/extension/src/providers/common/libs/new-features.ts	newNetworks changed from [CoreDAO] to [TAC].
