fix: disambiguate colliding schema type names

[lightsofapollo]

Closes #52

Summary

• detect component and generated-inline schema names that normalize to the same Rust model identifier
• preserve an exact canonical component name when present and suffix later collisions deterministically (SessionStatus2, etc.)
• rewrite local $ref, discriminator, dependency, pattern, operation, response, and query-type references to the disambiguated name
• remove the previous silent first-schema-wins behavior
• cover the reported SessionStatus / session.status reproduction

Validation

• cargo test --test schema_name_collision_test
• cargo test --all-features
• cargo clippy --all-features -- -D warnings
• cargo fmt -- --check
• git diff --check
• parse-only generation for all 10 corpus specs that exposed existing collisions in the initial CI run: Box, CircleCI, Cloudflare, Gcore, GitHub, Grafana, Increase, Lithic, Stripe, and Telnyx
