Major Changes

#92 4af6c06 Thanks @grod220! - Removed default serde support and replaced kaigan with spl-collections
BREAKING CHANGES:
- Generated variable-sized string/vector wrappers now come from spl-collections instead of kaigan. If you have handwritten code that references these generated wrapper types, update those imports and usages after regenerating your client:
  - kaigan::types::RemainderStr -> spl_collections::TrailingStr
  - kaigan::types::RemainderVec<T> -> spl_collections::TrailingVec<T>
  - kaigan::types::U8PrefixString, U16PrefixString, U64PrefixString -> spl_collections::U8PrefixedStr, U16PrefixedStr, U64PrefixedStr
  - kaigan::types::U8PrefixVec<T>, U16PrefixVec<T>, U64PrefixVec<T> -> spl_collections::U8PrefixedVec<T>, U16PrefixedVec<T>, U64PrefixedVec<T>
- serde is no longer part of the default or recommended generated client surface. The previous default derives on wrapper types were misleading because their serde representation does not match the Borsh/Wincode wire format.
- If you still want serde derives for a separate JSON representation, you can opt in explicitly via traitOptions as shown below. This does not make the generated types serde-compatible with their Borsh/Wincode wire format, but you can define a handwritten implementation with your own serde mapping as needed.
```
  traitOptions: {
    baseDefaults: [
      'borsh::BorshSerialize',
      'borsh::BorshDeserialize',
```
- ```
  'serde::Serialize',
```
- ```
  'serde::Deserialize',
  'Clone',
  'Debug',
  'Eq',
  'PartialEq',
],
```
- featureFlags: {
- ```
  serde: ['serde::Serialize', 'serde::Deserialize'],
```
- },
  }
#90 f214970 Thanks @grod220! - Switch generated Rust code from solana_pubkey::Pubkey to solana_address::Address and update the default dependency set to newer Solana 3.x and borsh 1.0 versions. This affects generated program IDs, account/instruction types, PDA helpers, and public key literals, so downstream users may need to update imports and pubkey usage after regenerating clients.
