v1.48.1

feat: cross-platform agent dispatch fully delivered (v1.48.1)

Completes the agent-dispatch platform-agnostic work: agent dispatch now
genuinely runs as native isolated subagents on all 4 target platforms
(Claude Code, OpenCode, Cursor 2.4+, Gemini CLI v0.38.1+).

• scripts/sync.ts: adaptAgentContent() normalizes Claude-specific model
  aliases (opus/sonnet/haiku) to inherit for non-Claude adapters; the
  claude-code adapter keeps the opus pinning. syncDir + fileHash are both
  transform-aware, so sync:discover stays 0-drift. AGENT_DIR_SKIP excludes
  AGENTS.md from sub-agent scan dirs (no more bogus "AGENTS" agent entry).
• core/skills/code-review/SKILL.md: review-checklist summary reworded to
  platform-neutral "4-dimension parallel review (Mode A dispatch)".
• mapping docs (multi-perspective-dispatch.md, sub-agent-isolation.md,
  proposal): primary-agent model:opus residual resolved — the last open
  item from the dispatch work is now closed.
• Backlog proposals triaged (verdicts in each proposal's 状态):
  #7 spec-distillation -> SHIP (pilot); #3 smart-hook-approval -> DEFER;
  #4 no-ask-human-hook -> DEFER (conflicts with human-gate philosophy).
• v1.48.1: CHANGELOG entry, package.json + README/DEV-PLAN version badges,
  README what's-new entries (en + zh).
