v7.1.1

Upgrade priority: Low. Recommended for users of contracts form Substrate master & Polkador/Kusama TS app developers where specific chain augmentation would be helpful.

Contributed:

• Expose storageDepositLimit on contract options (Thanks to https://github.com/kwingram25)

Changes:

• Expose @polkadot/api-augment/{kusama, polkadot, substrate} for specific augmentations (The bare @polkadot/api-augment is equivalent to /substrate, keeping the existing behavior)
• Expose @polkadot/types-augment/{lookup, registry} variants (The bare @polkadot/types-augment applies both)
• Expose txHash on submittable results, e.g. tx.signAndSend(..., ({ txHash }) => ...)
• Align casing for TS & exposed queries (adjusts for ALLCAPS entries)
• Additional tests for Option codec (explicit in expectations)
• Update to latest Substrate, Kusama & Polkadot static metadata
