Added

• Add 16 protocol-specific event types: L9SSHEvent, L9VNCEvent, L9FTPEvent, L9SMTPEvent, L9TelnetEvent, L9RedisEvent, L9MySQLEvent, L9PostgreSQLEvent, L9MongoDBEvent, L9MemcachedEvent, L9AMQPEvent, L9LDAPEvent, L9SIPEvent, L9RDPEvent, L9DNSEvent, L9RTSPEvent ([8f45e82], #18)
• Extend L9SSHEvent with enumeration fields for host keys, algorithms, and KEX methods ([8f45e82], #18)
• Add 32 round-trip and serialization tests covering to_dict(), Decimal field serialize/deserialize, and serde None-omission behavior ([d554f1e], #24)
• Add py.typed marker for PEP 561 compliance ([7f49ff5], #31)
• Add field-level assertions to deserialization tests ([cbea4fc], #26)
• Add 34 edge-case and validation tests covering missing fields, null values, empty strings, boundary integers, malformed datetimes/decimals, and nested validation ([1ca6e4d], #33)

Changed

• Bump minimum Python version from 3.13 to 3.11 for datetime.fromisoformat UTC suffix support ([82245e9], #18)
• Version bump to 1.4.0 ([8f45e82], #18)

• Re-export all public models from __init__.py and define __all__ ([1dcfbef], #21)
• Tests now import from l9format package directly instead of l9format.l9format ([e8aef2e], #21)

Fixed

• Fix leaked file handles in tests using context managers ([b66a6f5], #25)

• Add return type annotations to test functions for mypy compliance ([cd74b55], #43)
• Fix typo in test name: test_l9events_form_ip4scout -> test_l9events_from_ip4scout ([0d8736e], #27)

Infrastructure

• CI: drop Python 3.10 from test matrix ([82245e9], #18)
• Add mypy type checking with serde-compatible configuration ([fac243d], #16)
• Add .editorconfig for consistent editor settings ([fac243d], #16)
