feat(caipe-cli): encrypted credentials, Ink5 TUI rewrite, readline keybindings, usage docs

- Rewrite Repl.tsx: all text in <Static> (no flashing), line-buffered
  streaming, slash command picker, readline-style cursor movement
- Add AES-256-GCM encrypted credential storage (default backend),
  keytar optional via auth.credential-storage setting
- Add cli/README.md with install, usage, and development docs
- Replace agent-chat-cli references across all docs/agents with caipe CLI
- Add Makefile targets: caipe-cli-test, caipe-cli-lint, caipe-cli-build
- Update caipe-ci.yml to use vitest, fix Biome lint errors
- Add Up/Down arrow input history navigation
- Improve markdown rendering with chalk-styled marked-terminal
- Add vitest.config.ts, build-binary.mjs (Node SEA), pipes.ts (shell/pipe)
- Fix env var cleanup in tests (use empty string instead of undefined)
