File-Level Changes

Change	Details	Files
Introduce helper types and factory for building ExplicitSessionConfig with optional native token spending constraints.	Add SessionDuration, NativeTokenSpending, and ExplicitSessionParams types to describe session lifetimes, permissions, and native token limits. Implement createExplicitSessionConfig to compute a deadline from relative durations, validate presence of permissions, derive value limits and per-recipient spending permissions, and return an ExplicitSessionConfig. Re-export VALUE_FORWARDER_ADDRESS constant from dapp-client utils.	packages/wallet/dapp-client/src/utils/index.ts
Expand dapp-client public API surface for session helpers, network utilities, and primitives needed by new login flows.	Export createExplicitSessionConfig, VALUE_FORWARDER_ADDRESS, and session parameter types from the dapp-client entrypoint. Re-export getNetwork, getRelayerUrl, and getRpcUrl from utils through the main dapp-client index. Add Network to the set of primitives re-exported from @0xsequence/wallet-primitives.	packages/wallet/dapp-client/src/index.ts
Version bump and changelog entries for 3.0.0-beta.9 across services, wallet, and utility packages to reflect dapp client EOA login updates.	Add 3.0.0-beta.9 sections to multiple package changelogs referencing dapp client EOA login updates and dependency bumps. Increment package.json versions from 3.0.0-beta.8 to 3.0.0-beta.9 for affected packages. Add a changeset file describing patch releases for the touched packages.	packages/wallet/wdk/CHANGELOG.md packages/wallet/dapp-client/CHANGELOG.md packages/wallet/core/CHANGELOG.md packages/services/relayer/CHANGELOG.md packages/services/api/CHANGELOG.md packages/services/builder/CHANGELOG.md packages/services/guard/CHANGELOG.md packages/services/identity-instrument/CHANGELOG.md packages/services/indexer/CHANGELOG.md packages/services/marketplace/CHANGELOG.md packages/services/metadata/CHANGELOG.md packages/services/userdata/CHANGELOG.md packages/utils/abi/CHANGELOG.md packages/wallet/primitives/CHANGELOG.md packages/services/api/package.json packages/services/builder/package.json packages/services/guard/package.json packages/services/identity-instrument/package.json packages/services/indexer/package.json packages/services/marketplace/package.json packages/services/metadata/package.json packages/services/relayer/package.json packages/services/userdata/package.json packages/utils/abi/package.json packages/wallet/core/package.json packages/wallet/dapp-client/package.json packages/wallet/primitives/package.json packages/wallet/wdk/package.json .changeset/tiny-files-chew.md
