Add test files for Lex, Federation, Palam, and Pons native contracts

Add comprehensive test suites for four native contracts:

Lex (22 tests):
- Law count and queries for non-existent laws
- Constitutional rights retrieval (14 immutable rights)
- Rights restriction with due process requirements
- Law lifecycle (enact, repeal, suspend, reinstate)

Federation (18 tests):
- Fee percent configuration (default 50%)
- Visitor registry (register, unregister, queries)
- Asylum system (grant, revoke, queries)
- Naturalization (permanent citizenship transfer)
- Inter-chain debt tracking and settlement

Palam (19 tests):
- Transaction flow tracking (record, attach, query)
- Encrypted payload management
- Declassification requests (role-based authorization)
- Access logging and auditing

Pons (22 tests):
- Bilateral agreement lifecycle
- Cross-border verification requests
- International settlement workflow
- Credential sharing with partner chains

All tests follow existing neotest patterns and pass successfully.
