Changes:

• Added sw_utils/release.py with is_vault_upgraded_to_release(...) and related helpers.
• Extended BaseNetworkConfig with CONTRACTS_RELEASES and added V4/V5 release thresholds for MAINNET/HOODI/GNOSIS.
• Removed the legacy sw_utils/pectra.py helper and bumped the package version.

sw_utils/pectra.py:1

• sw_utils/pectra.py is removed, which is a breaking change for any downstream code that imports sw_utils.pectra / get_pectra_vault_version. If this removal is intentional, consider keeping a thin compatibility wrapper (e.g., get_pectra_vault_version delegating to the new release-based logic) and/or doing a major version bump with a deprecation period instead of removing the module outright in a patch release.
