* fix(parser): #283 collect errors from all erroneous statements in multi-statement input (#470)

* test(parser): #283 add multi-statement error validation tests for all dialects

* fix(parser): #283 collect errors from all erroneous statements in multi-statement input

* feat: add generic SQL language support (#469)

* fix(generic): fix INTERSECT/EXCEPT support, trim keywords to ~90

- Add INTERSECT and EXCEPT to queryNoWith rule for set operations
- Remove 173 unused KW_* lexer rules for removed features (views, indexes,
  grants, transactions, stored procedures, window functions, triggers, etc.)
- Trim nonReserved list to only keywords actually used in parser rules
- Remove unused UNICODE_STRING and DIGIT_IDENTIFIER lexer rules
- Keyword count reduced from 263 to 90 (close to ~100 target)
- All 197 test suites pass (5627 tests)

* fix(generic): reserve core structural keywords and add DIGIT_IDENTIFIER

- Remove core structural keywords from nonReserved so they cannot be
  used as identifiers: SELECT, FROM, WHERE, CREATE, TABLE, INSERT,
  UPDATE, DELETE, DROP, ALTER, SET, JOIN, GROUP, HAVING, ORDER, ON,
  UNION, INTERSECT, EXCEPT, INTO, NOT, AND, OR, IN, BETWEEN, LIKE,
  IS, EXISTS, CASE, WHEN, THEN, ELSE, END, CAST, AS, DISTINCT,
  PRIMARY, CONSTRAINT, REFERENCES, COLUMN, UNIQUE, CHECK, FOREIGN,
  RENAME, RECURSIVE, WITH, NULL, ESCAPE, NULLIF
- Add DIGIT_IDENTIFIER lexer token for identifiers starting with a
  digit (e.g. 123abc, 1st_column)
- Include DIGIT_IDENTIFIER in identifier rule alternatives

* fix(generic): add missing Listener/Visitor exports and diagnostics option

- Add GenericSqlListener and GenericSqlVisitor exports to src/index.ts
- Add GenericSQLOptions interface with configurable diagnostics flag
- Override validate() to return empty array when diagnostics disabled
- Export GenericSQLOptions type from src/index.ts

* fix(generic): add QUERY_RESULT and SELECT column entity collection

- Add exitQuerySpecification for QUERY_RESULT entity tracking
- Add exitSelectItem for column entity collection in SELECT clauses
- Track wildcard columns (ColumnDeclareType.ALL) for * and table.*
- Track expression columns with alias support (ColumnDeclareType.EXPRESSION)
- Stage previously untracked files (errorListener, splitListener, semanticContextCollector)

* test: add GenericSQL tests

* test: ensure all dialect tests pass with GenericSQL

* test(generic): add more sql test

- Add comprehensive syntax tests for all supported statement types
- Add context collect tests for entity and semantic collectors
- Add suggestion tests for token, syntax, and multi-statement scenarios
- Add error strategy, listener, visitor, and validation tests
- Fix entity collector to distinguish simple columns from expressions
