Pull request overview

Adds a Kotlin Exposed dialect module for YDB, including YDB-specific SQL/DDL generation, type mappings, and supporting utilities, plus comprehensive unit/integration tests, documentation, and a runnable example.

Changes:

• Implemented YDB dialect components: data type provider, function provider (UPSERT/LIMIT/OFFSET), table/ID/index/TTL helpers, retrying transactions, keyset pagination, optimistic locking, and JDBC metadata support.
• Added unit + integration test suites covering core behavior (types, UPSERT, TTL, indexes, DAO/DSL flows, retry, pagination, joins/subqueries).
• Added build/CI wiring (Maven config, Docker Compose for local YDB, GitHub Actions workflow) and end-user docs/example app.
