refactor(repo)!: opensop is now the standard (spec + CLI); Rails server → opensop-rails (#68)

OpenSOP becomes "Process as Infrastructure for agentic processes." This repo
now holds the standard — the specification (SPEC.md, with the /sop/* HTTP
contract folded in), the manifesto, and the local-first CLI (cli/). The Rails
runtime was extracted (history preserved) into a separate repo,
Chosen9115/opensop-rails, as one reference implementation of the spec.

- Remove the Rails app (app/ config/ db/ lib/ spec/ Gemfile Dockerfile fly.toml
  .kamal/ etc.) — now lives in opensop-rails
- Add MANIFESTO.md; fold docs/API.md into SPEC.md (§ Server HTTP API)
- Marie Kondo: delete SPEC-v0.2, v0.2-roadmap, HANDOFF, GAPS, api-docs-redesign-spec;
  merge 6 agent/install docs → one docs/AGENTS.md; delete the Rails server-install docs
- Reframe README/CLAUDE/SECURITY/CONTRIBUTING/processes for the standard+CLI repo;
  point server concerns at opensop-rails
- .gitignore: exclude .claude/, .worktrees/, research/, scratch PNGs, doc drafts

BREAKING CHANGE: the Rails runtime no longer lives in this repo. Use
github.com/Chosen9115/opensop-rails (or any spec-conformant server). The CLI is
local-first and needs no server.
