chore(cli): add no value test cases for max length rules

[KeisukeYamashita]

Why

Because there is a case where there are no values but the rules exist.
Max length rules should bypass None which means 0.

Walkthrough

Adds new unit tests covering no-value scenarios for BodyMaxLength, ScopeMaxLength, and TypeMaxLength rules. Each test constructs a rule with usize::MAX and a Message with None for the respective field, asserting validate returns None. No production code or public APIs changed.

Changes

Cohort / File(s)	Summary
Unit tests for max-length rules cli/src/rule/body_max_length.rs, cli/src/rule/scope_max_length.rs, cli/src/rule/type_max_length.rs	Added tests (test_no_body, test_no_scope, test_no_type) asserting no violation when corresponding Message field is None with rule length set to usize::MAX. No implementation or API changes.

Poem

I hop through specs with tidy cheer,
New tests nibble edges clear.
When fields are None, no flags arise—
Lengthy limits, quiet skies.
Thump, thump: green pastures draw near.
