test: add DialectAbstract edge case coverage tests
Added comprehensive edge case tests to reach 90%+ coverage: SharedCoverageTest (+3 tests): - testQuoteTableWithAliasUsingAS() - table alias with AS keyword - testNormalizeJsonPathWithEmptyString() - empty JSON path handling - testFormatDefaultValueWithNumbers() - numeric default values PdoDbSqliteTest (expanded buildLoadCsvSql): - NULL/empty values in CSV (treated as empty strings) - CSV with more columns than expected (truncation) - CSV with less columns than expected (padding with NULL) - Empty CSV file (returns empty SQL) - CSV with only blank lines (returns empty SQL) - Unreadable file exception PdoDbSqliteTest (expanded buildLoadXML): - XML with attributes (id="1" name="Alice") - XML with empty elements (<name></name>) - Empty XML file (returns empty SQL) - Unreadable file exception Coverage improvements: - DialectAbstract::quoteTableWithAlias() AS branch - DialectAbstract::normalizeJsonPath() empty path handling - DialectAbstract::formatDefaultValue() non-string values - DialectAbstract::buildLoadCsvSql() all edge cases (NULL, empty, batching, validation) - DialectAbstract::buildLoadXML() all edge cases (empty, attributes, validation) Tests: 326 total, 1491 assertions, all passing ✅ Expected coverage increase: 83% → 90%+
