Breaking release to update Kintsugi to the latest runtime. This contains, but is not limited to, the following changes:

• Vaults can now self-redeem (burn kBTC for unlocking collateral) without sending BTC
• Removed the refund protocol since theft reporting was already eliminated
• Issue requests can now be executed after expiry if the Vault has sufficient collateral
• Allows issue requests to be cancelled prematurely by the user (may slash griefing collateral)
• Collators can now lock vKINT to register as an authority
• Adds generic registry to store client release info (for auto-updater)
• Includes all relevant changes to support polkadot-v0.9.26

For more details, please see the following:

Collators

After deliberation, it was agreed with the community that we trial public collator registration. Initially nine slots will be made available requiring a deposit of >1000 vKINT to be locked. If the balance falls too low or the collator fails to produce blocks they will be kicked.
