- Fix session-planner to include adaptive-bkt in BKT targeting logic

BKT targeting, not the cost formula - using BKT for both simplifies
the architecture with no performance cost.

Comprehensive test harness for comparing BKT-driven adaptive mode vs
classic mode using simulated students with Hill function learning.
Key components:
- SimulatedStudent: Exposure-based learning model with conjunctive
skill probability (P = product of individual skill probabilities)
- JourneyRunner: Runs multi-session practice journeys
- Per-skill deficiency profiles: 32 skills × 3 learner types (96 profiles)
- Per-skill assessment: Measures exposure and mastery on specific skills
WITHOUT learning during assessment
Learner types calibrated for gradual learning over 12 sessions:
- Fast: K=25, n=2.0 (~75 exposures for 90% mastery)
- Average: K=40, n=2.5 (~120 exposures for 90% mastery)
- Slow: K=60, n=3.0 (~150 exposures for 90% mastery)
Key finding: When measuring the RIGHT metric (deficient skill exposure
and mastery), adaptive mode wins 10/15 comparisons vs classic:
- Avg deficient skill exposure: Adaptive=189.6 vs Classic=180.6
- Avg deficient skill mastery: Adaptive=94.9% vs Classic=90.8%

Validates BKT's ability to identify weak skills using the real problem
generator with deterministic seeding:
- Generates 15,000+ problems covering all 34 skills (400+ per skill)
- Tests each skill by answering 200 correctly and 200 incorrectly
- Verifies BKT identifies each skill as weak (P(known) < 0.6)
- Achieves 100% identification accuracy with sufficient data
Key findings:
- With 100 problems per skill: 82.4% accuracy (6 skills escaped due to
conjunctive model blame distribution)
- With 400 problems per skill: 100% accuracy (all skills correctly
identified as weak)
This confirms BKT's conjunctive model works correctly - it just needs
sufficient data to overcome blame distribution effects when skills
co-occur.

The problem generator was failing with ProblemGenerationError when
minComplexityBudgetPerTerm was set (e.g., challenge slots requiring
complexity >= 1). The issue: skill complexity depends on abacus state,
not just the term value. Adding +4 from 0 is basic (cost 0), but adding
+4 from 7 triggers fiveComplements (cost 1).
The old algorithm filtered terms by minBudget during collection, causing
empty candidate lists when no term could meet the budget at that state.
Fix: Two-phase approach in collectValidTerms() that categorizes ALL
valid terms into meetsMinBudget and belowMinBudget arrays. The selection
prefers high-cost terms but gracefully falls back to lower-cost terms
when the budget is impossible to meet at the current abacus state.
Also adds 31 comprehensive tests covering state-dependent skill
detection, graceful fallback, edge cases, stress tests (1000 problems),
and performance verification.

- Remove sessionRef imperative handle (no longer needed)
- Fix auto-pause re-triggering immediately after resume by resetting timer
- Update PracticeClient to remove duplicate modal and pause state

Previously, there were two pause states that could get out of sync:
1. PracticeClient's isPaused (controlled modal visibility)
2. ActiveSession's internal phase.phase === 'paused' (controlled input)
Now ActiveSession owns both the modal and the pause state, eliminating the sync issue.

When the auto-pause modal was dismissed via the Resume button, the modal
would hide but input would remain blocked. This was because:
1. PracticeClient has isPaused state (controls modal visibility)
2. ActiveSession has internal phase.phase='paused' (controls input acceptance)
When the modal's Resume button was clicked, only PracticeClient's state
was updated, leaving ActiveSession stuck in 'paused' phase.
Fix: Add sessionRef prop to ActiveSession that exposes resume/pause
handlers, allowing PracticeClient to trigger ActiveSession's internal
resume when the modal is dismissed.
Long-term: Consider moving the modal inside ActiveSession so there's
a single source of truth for pause state.
