Accept Swedish High reasoning label

[HenrikDanielsson]

What changed

• Treat the user-facing reasoning labels High and Swedish Hög as the same semantic high level after trim/case normalization.
• Keep model matching exact and machine/config evidence canonical lowercase high.
• Apply the rule consistently in the orchestration skill, native role contract, and README.
• Add verification assertions covering the localized-label contract.

Why

Codex Desktop localizes the High reasoning label as Hög in Swedish. Sol Advisor previously named only High, so a correctly configured Sol / high primary task could hit a false blocker solely because the UI label was localized.

The accepted-label set remains deliberately narrow: only high and hög normalize to the required semantic level. Different or unobservable effort evidence retains the existing stop/confirmation behavior.

Validation

• sh plugins/sol-advisor/scripts/verify.sh — passed, including the new High/Hög assertion.
• python3 .../skill-creator/scripts/quick_validate.py plugins/sol-advisor/skills/orchestration — Skill is valid!
• git diff --check — passed.
• Fresh Sol review — ship, no findings.
