Dialect-aware DELETE-query rendering & DELETE LIMIT support

[ez-plugins]

Features

• Dialect-aware DELETE rendering - SqlDialect now exposes a renderDelete(Query) method that generates
  a fully dialect-aware DELETE FROM … WHERE … statement, including proper identifier quoting per dialect.

Improvements

• MySQL DELETE … LIMIT - MySqlDialect now appends a LIMIT clause to DELETE statements when a limit
  is set on the query.
• SQLite DELETE … LIMIT - SqliteDialect does the same; standard dialect silently ignores limit on
  DELETE to remain ANSI-compliant.
• appendWhereClause and appendConditionFragment in AbstractSqlDialect promoted to protected so
  subclasses can reuse the shared WHERE rendering logic.

Tests

• Added AbstractSqlDialectDeleteTest covering parameter parity with render(), identifier quoting,
  LIMIT behaviour across all three dialects, and IN placeholder generation.

Chores

• Version bumped to 1.0.4
• README updated: dialect comparison table now includes a DELETE LIMIT column; new
  Dialect-aware DELETE rendering subsection with code examples for all three dialects.
