feat(scenarios): add support for Kamino programs

[bakasura980]

Greptile Summary

The PR expands native scenario support across six Kamino programs and adds persistent overrides, indexed array paths, fixtures, templates, documentation, and an example liquidation scenario.

• Registers Kamino Lend, Scope, Farms, Swap, Vault, and Liquidity templates.
• Adds type-aware traversal and mutation of nested struct and array paths.
• Re-applies overrides on later slots when persist is enabled.
• Adds round-trip and targeted coverage for Kamino account forging.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains.

The persisted re-fetch issue is fixed, but two different fetchBeforeUse overrides for the same account in one slot still fetch independently, so I believe the second drops the first change
