Rename plugins/os-orchestration -> plugins/os-context. SessionStart hook is
now a composer: globs prompts/session-start/*.md in filename order, emits one
additionalContext block, byte-identical for the existing orchestration rules
(tested), line budgets enforced (warn 120 / refuse 240). ORCHESTRATION.md ->
prompts/session-start/10-orchestration.md. New prompt files from the
2026-07-09 audit: 20-kickoff-conventions, 30-standing-safety,
40-decision-memos (total injection 102/120 lines). os-status audit-skill and
state-path references updated (old ~/.local/state path symlinked;
OS_ORCH_AUDIT_LEDGER name kept for compatibility).
