In interactive mode, EXIT(query) can now span multiple lines when parentheses are unbalanced. The shell prompts for continuation lines until parentheses balance, matching ODBC sqlcmd behavior. Changes: - Add isExitParenBalanced() to check paren balance respecting quotes - Add readExitContinuation() to prompt for additional lines - Update exitCommand() to call continuation when needed - Add TestIsExitParenBalanced tests - Remove limitation note from README

Pull request overview
This pull request implements multi-line EXIT(query) support in interactive mode for go-sqlcmd. When an EXIT command with parentheses is entered and the parentheses are unbalanced, the shell now prompts for continuation lines until the parentheses balance, matching the behavior of ODBC sqlcmd.
Changes:
- Added
isExitParenBalanced()function to check if parentheses in EXIT command arguments are balanced - Added
readExitContinuation()function to prompt for and read continuation lines in interactive mode - Updated
exitCommand()to call continuation logic when parentheses are unbalanced - Added comprehensive test suite for
isExitParenBalanced() - Removed the README limitation note about EXIT(query) not supporting multi-line

| File | Description |
|---|---|
| pkg/sqlcmd/commands.go | Implements core multi-line EXIT(query) functionality with parentheses balancing check and continuation prompt logic |
| pkg/sqlcmd/commands_test.go | Adds test cases for the new isExitParenBalanced() function covering various edge cases |
| README.md | Removes the documented limitation about EXIT(query) not supporting multi-line queries |
- Fix isExitParenBalanced to handle SQL Server quote escaping rules:
- Escaped single quotes ('') inside string literals
- Escaped bracket identifiers (]])
- Add test cases for escaped quotes in TestIsExitParenBalanced
- Add comprehensive TestReadExitContinuation tests:
- Continuation lines until balanced
- Error handling on readline failure
- Multiple continuation lines
- Early return for already balanced input

- Add TestExitCommandMultiLineInteractive: exercises the full multi-line EXIT flow with real database connection (unbalanced parens -> read continuation -> execute query -> verify exit code) - Add 'Interactive Mode Commands' section to README with EXIT examples showing both single-line and multi-line usage with continuation prompt

In interactive mode, EXIT(query) can now span multiple lines when parentheses are unbalanced. The shell prompts for continuation lines until parentheses balance, matching ODBC sqlcmd behavior. Adds isExitParenBalanced() function, readExitContinuation() for prompting, updates exitCommand(), adds tests, and removes README limitation note.
