feat(config): relocate orchestration loop/threshold/budget constants to [orchestration] config

The kernel's ReAct-loop tuning constants (max tool rounds, read/rejection-loop
nudge thresholds, feedback issue cap, repo-map top-k/files-per-dir, docs catalog
cap, clarification-round cap, review-block confidence/retry cap, default
refinement, recovery/intent route budgets) were hardcoded in SessionOrchestrator/
DefaultSessionOrchestrator. Relocated to a new OrchestrationTuning value threaded
through the orchestrator constructor, mapped from CorrexConfig.orchestration in
Main.kt, parsed in ConfigLoader, written by CorrexConfigWriter. Defaults equal the
former constants so an absent [orchestration] section reproduces prior behavior.

Startup-load (not hot-reload); pure output-truncation caps left as constants.

Vikunja #46 (task 76).
