refactor!: rename nssa crate to lee

BREAKING CHANGE:
- Crate `nssa` renamed to `lee`; update `Cargo.toml` dependencies from `nssa = { workspace = true }` to `lee = { workspace = true }`.
- Crate `nssa_core` renamed to `lee_core`; update similarly.
- Crate `key_protocol` moved under `lee`; update `Cargo.toml` dependencies from `key_protocol = { workspace = true }` to `lee_key_protocol = { workspace = true }`.
- Type `NSSATransaction` (in `common`) renamed to `LeeTransaction`.
- Error type `nssa::error::NssaError` renamed to `lee::error::LeeError`.
- Error type `nssa_core::error::NssaCoreError` renamed to `lee_core::error::LeeCoreError`.
- All `use nssa::` and `use nssa_core::` import paths must be updated to `use lee::` and `use lee_core::` respectively.
- Guest programs must replace `write_nssa_outputs` with `write_lee_outputs`.
- The sequencer RocksDB column family for the chain state was renamed. Existing databases are incompatible and must be wiped before running the new version.
- Domain separators updated: `"NSSA_seed"` → `"LEE_seed"` (key derivation), `"NSSA/v0.2/KDF-SHA256/"` → `"LEE/v0.2/KDF-SHA256/"` (encryption KDF), `"/NSSA/v0.2/AccountId/PDA/"` →
  `"/LEE/v0.2/AccountId/PDA/"` (public PDA address derivation). All previously derived keys, encrypted outputs, and public PDA addresses are invalidated.
