nullkey f2e8e3f56c refactor(cli): drop aiclient package; align AGENTS.md with mainstream
Survey of 10 mainstream CLIs (gh, lark, stripe, vercel, supabase, aws,
azure, gcloud, openai/codex, github-copilot-cli) showed env-gated
per-command --help blurbs are a Stripe-only pattern; gh uses env detect
for telemetry only, and lark relies on installed agent Skills + MCP.
Our cmd/mcp/serve already covers the dominant 2025/26 path, so
internal/aiclient/ (136 LOC + 38 callsites) is net maintenance burden
without precedent.

- Drop internal/aiclient/ entirely (annotations + detect + tests)
- Remove 38 SetAgentHelp callsites + agentAwareHelpFunc / SetHelpFunc
  wiring in cmd/root.go
- Migrate 4 command-level rules to standard Long help (visible to all,
  not env-gated): doc upload mode mutex, kb edit at-least-one,
  kb pin idempotent, search chunks channel mutex
- Rewrite AGENTS.md as a developer guide (gh-style 6 H2 / 167 lines):
  audience preamble + Build / Architecture / Command Structure /
  Testing / Code Style / Error Handling. Drops sections absent in
  surveyed projects (Commit & PR Conventions, Who Uses This CLI)
- Clean 14 internal doc refs (ADR-N, spec §X, v0.X) in source comments
  and docs that pointed at docs/superpowers/ — that directory is
  local-only / uncommitted, so refs are dead for outside readers
- Drop forward-looking "once v0.2 ships" from README
