René Cannaò	7e49c41975	Address review feedback on server selection (PR #5508 ) - Fix truncation: use uint64_t modulo instead of unsigned int cast when computing target from total_weight (prevents skewed selection when total_weight > UINT_MAX) - Remove unused #include <cstdlib> - Add docstring note about max_latency_us=0 semantics: in production this means "use thread default", this extraction treats it as "no limit" — callers should resolve defaults before populating the struct - Remove trailing "fix" comment from test	3 weeks ago
René Cannaò	7697d4f43e	Add server selection unit tests (Phase 3.4, #5492 ) 21 test cases covering: - Eligibility: all 5 status types, max_connections, latency, repl lag, disabled limits (max=0) - Selection: single server, empty list, all offline, weight=0 - Weighted distribution: equal weights → ~50/50, 3:1 → ~75/25 (statistical verification over 10000 iterations) - Determinism: same seed produces same result - Mixed eligibility: only eligible server selected 100% of the time	3 weeks ago

Address review feedback on server selection (PR #5508 )

- Fix truncation: use uint64_t modulo instead of unsigned int cast
  when computing target from total_weight (prevents skewed selection
  when total_weight > UINT_MAX)
- Remove unused #include <cstdlib>
- Add docstring note about max_latency_us=0 semantics: in production
  this means "use thread default", this extraction treats it as "no
  limit" — callers should resolve defaults before populating the struct
- Remove trailing "fix" comment from test

Add server selection unit tests (Phase 3.4, #5492 )

21 test cases covering:
- Eligibility: all 5 status types, max_connections, latency, repl lag,
  disabled limits (max=0)
- Selection: single server, empty list, all offline, weight=0
- Weighted distribution: equal weights → ~50/50, 3:1 → ~75/25
  (statistical verification over 10000 iterations)
- Determinism: same seed produces same result
- Mixed eligibility: only eligible server selected 100% of the time
