fix: infinite loops, resource leaks, and memory management issues (#1048)

## Summary
- Fix infinite loop vulnerability in wait-for-completion.ts where
timeout checks occurred after sleep operations, causing 5+ second
overshoots
- Resolve resource leak in execute-command.ts where stdin pipes weren't
properly cleaned up in error scenarios
- Fix race condition in login.ts STDIN reading with proper EOF handling
and 30-second timeout instead of 1-second race
- Improve error isolation in minio functions.ts by switching from
Promise.all to Promise.allSettled to prevent cascade failures
- Prevent memory leaks in postgres.ts by implementing WeakSet tracking
for event listeners and preventing concurrent retry attempts
- Add proper timeout cleanup in schema-processor.ts Promise.race
scenarios to prevent resource leaks
- Implement comprehensive input validation in parse-number.ts to prevent
NaN/Infinity propagation throughout the system

## Test plan
- [x] Created comprehensive test suite with 25+ test cases across 5 new
test files
- [x] All fixes pass TypeScript compilation and type checking
- [x] Code passes linting with appropriate biome-ignore comments for
test mocking
- [x] Package exports validation confirms no breaking changes
- [x] Build process completes successfully with all optimizations
- [x] Core functionality tests demonstrate proper timeout handling,
resource cleanup, and error isolation

## Summary by Sourcery

Fix critical bugs and improve robustness across multiple SDK packages by
addressing infinite loops, resource and memory leaks, race conditions,
and timeout handling, while enhancing input validation and expanding
test coverage.

Bug Fixes:
- Check timeouts before sleeping in wait-for-completion to prevent
infinite loops and overshoot
- Cleanup stdin pipes in execute-command on error and close to avoid
resource leaks
- Add proper EOF handling and 30s timeout for STDIN in login command to
fix race conditions
- Switch MinIO file operations from Promise.all to Promise.allSettled
with per-item error isolation
- Implement WeakSet tracking and retry guard in Postgres pool error
handler to prevent memory leaks and concurrent retries
- Refine schema-processor timeout promise to include cleanup and prevent
dangling timers
- Enforce finite, non-negative size parsing in MinIO metadata handling

Enhancements:
- Introduce strict input validation in parse-number to reject NaN,
Infinity, and empty strings

CI:
- Update ci:local script to use biome formatter

Tests:
- Add new test suites for wait-for-completion, parse-number, and
Postgres error handling to cover timeout, loop behavior, and cleanup
scenarios

## Summary by CodeRabbit

- **Bug Fixes**
- Improved error handling and recovery for PostgreSQL connections,
including better retry logic and prevention of memory leaks.
- Enhanced validation for database connection strings and numeric
parsing, with clear error messages for invalid inputs.
- Prevented CLI processes from hanging when reading tokens from STDIN by
adding a timeout mechanism.
- Improved handling of command execution in the terminal utility,
ensuring stdin streams are always cleaned up.

- **New Features**
- Added configuration to exclude certain files and directories from test
coverage analysis.

- **Tests**
- Introduced comprehensive test suites for PostgreSQL connection
handling, number parsing, CLI login, command execution, and resource
completion utilities.

- **Chores**
- Updated local continuous integration script to use a specific
formatting tool for consistency.

- **Refactor**
- Improved timeout handling in schema fetching utilities to ensure
proper cleanup and resource management.
- Updated file listing logic to handle individual errors gracefully when
generating URLs.
