Bump the LEZ dependency from the `v0.2.0-rc3` tags to the released
`lez-core-v0.2.0` tag across the workspace and all guest manifests. The crate
was renamed upstream, so `nssa_core`/`nssa` now resolve via the `lee_core`/`lee`
packages, and spel-framework points at the `refactor/lez-v020-compat` fork
branch for compatibility.
Adapt the integration tests to the new API surface:
- `NssaError` is now `LeeError` (error variants unchanged).
- Account inputs move from numeric mask vectors (`vec![2, 0, 0]`) to typed
`InputAccountIdentity` values (e.g. `PrivateUnauthorized { epk, view_tag,
npk, ssk, identifier }`).
- `ViewingPublicKey::from_scalar` → `from_seed(d, z)`; `AccountId::from(&npk)`
→ `AccountId::for_regular_private_account(&npk, 0)`; ephemeral-key/shared-
secret setup → `SharedSecretKey::encapsulate_deterministic(...)` with the
circuit filling the EPK.
Regenerate all guest Cargo.lock files and the workspace lockfile to match.
Replace the hardcoded numeric byte-stream seeds ([0; 32], [1; 32], ...)
used for domain separation in PDA derivation with descriptive byte-string
constants, mirroring the AMM config account's existing b"CONFIG" seed.
amm: [0; 32] -> b"LIQUIDITY_TOKEN"
[1; 32] -> b"LP_LOCK_HOLDING"
stablecoin: [0; 32] -> b"POSITION"
[1; 32] -> b"POSITION_VAULT"
twap_oracle: [2; 32] -> b"PRICE_OBSERVATIONS"
[3; 32] -> b"ORACLE_PRICE_ACCOUNT"
[4; 32] -> b"CURRENT_TICK_ACCOUNT"
Since the seeds are now variable-length, each compute_*_pda_seed function
builds its hash input with a Vec and extend_from_slice instead of a
fixed-size buffer with offset writes.
Closes#146
