feat(voyage): add 5 additive profile fields to JSONL stats — SC #11

Step 8 av v4.1-execute (Wave 3, Session 4).

5 nye additive felter er nå dokumentert i hver kommandos prose-stats-blokk
(via Profile-seksjonen fra Step 7 — felles overflate per kommando):
- profile           — string ('economy' | 'balanced' | 'premium' | <custom>)
- phase_models      — object form {brief: 'sonnet', ..., continue: 'opus'}
- parallel_agents   — number (snapshot av maksverdi som faktisk ble brukt)
- external_research_enabled — boolean
- profile_source    — 'flag' | 'env' | 'default' | 'inheritance'

Patcher trekresearch.md med eksplisitt profile_source-mention + alle 5 felter
(de andre 5 commands hadde dette allerede via Step 7 Profile-seksjon).

SC #11 contract-test design (per brief):
(a) Fixture-records valideres som JSONL-contracts → tests/fixtures/stats-with-profile.jsonl
    (5 simulerte stats-rader, én per kommando-overflate)
(b) Command-prose contains field-names → kompenserer for plan-critic Major 4
    false-confidence (faktisk runtime-emission er LLM-prose-driven, ikke
    testbart i node:test alene).

Tester (12 nye, baseline 445 → 457):
- Fixture parses som JSONL (5 records)
- Hver record har profile + profile_source
- profile_source-verdier i {flag, env, default, inheritance}
- Fikstur dekker alle 4 profile_source-verdier
- 6 commands × prose contains profile + profile_source
- trekplan.md prose contains phase_models + parallel_agents
- trekresearch.md prose contains external_research_enabled

+Stats records emit `profile`, `phase_models`, `parallel_agents`,
+`external_research_enabled`, and `profile_source` so operators can audit
+which profile drove which session.
