fix: address stakeholder review findings

Fixes from 5-stakeholder review (architect, privacy, perf, markers, tests):

- Marker fix: remove nested altimate_change start/end, fold new variables
  into existing session telemetry tracking block
- Performance: cap errorRecords at 200 entries (prevent unbounded growth)
- Performance: slice intent classifier input to 2000 chars (bound regex)
- Architecture: fix import path in sql-execute.ts (../telemetry not ../../altimate/telemetry)
