v0.2.1: polish, deploy, CI, and literate refactor

- Secret Exposure Gate + Privacy Filter (Bouncer)
- Shell actuator safety harness (timeout, blocked patterns)
- REPL-first enforcement (lisp validation gate, system-prompt-augment)
- Engineering Standards lifecycle (two-track Org-first + REPL-first)
- Literate Programming discipline (one function per block, reflect-back)
- AGENTS.md: thin routing layer, skills are authoritative
- SKILLS_DIR removed, ~/notes fallback eliminated
- opencortex.sh: multi-distro (Debian+Fedora), configure, install service, backup, restore, help
- infrastructure/opencortex.service (systemd user unit)
- Docker: updated to debian:trixie, fixed build context
- GitHub CI: lint + test workflows fixed, trigger on tags only
- Gitea CI: deploy workflow paths fixed
- README: one-line curl install, badges
- USER_MANUAL: Deployment section (bare metal, Docker, backup)
- .gitignore: skills/*.lisp and tests/*.lisp as generated artifacts
- Prose/block refactor across all 35 org files
- Test suite Tier 1: 43/45 pass (env-dependent failures isolated)

+** Protocol Smoke Test (manual for REPL evaluation)
+The following script connects to a running daemon, sends "hi", and reads the response. Useful for verifying the daemon is alive and the framing protocol works end-to-end.
