refactor: remove Makefile, restructure as knowledge-first framework

The primary value is the knowledge layer (markdown files that any agent
reads — Crush, OpenWebUI, Hermes, Conduit on iPhone). CLI tooling
(scripts, git hooks) is optional, for projects that use git/docker.

Changes:
- Remove Makefile entirely. All commands are now direct script invocations
  (bash scripts/check-rules.sh, bash scripts/setup-hooks.sh, etc.)
- Add scripts/test.sh stub (replaces make test)
- check-rules.sh: test-suite check now calls scripts/test.sh, not make test
- Rewrite README as three-layer architecture: knowledge → git hooks → docker
- Update all docs (AGENTS.md, BASELINE-PROMPT.md, ADOPTING.md, PATTERNS.md,
  STATUS.md) to remove every make reference

The framework now works for:
- CLI/harness users (git hooks + scripts + AGENTS.md)
- Non-CLI users (BASELINE-PROMPT.md loaded into any agent's system prompt)

STATUS.md

@@ -16,8 +16,8 @@ Pending: push to TSYSGroupCorporate/TSYSGroupAIOS (Q1).
 - Removed docs/JOURNAL.md (Q5). Redmine is the SoR for work; Discourse for docs. JOURNAL.md was a stopgap.
 - Added Discourse pointer-header check to check-rules.sh (Q3) — MANDATORY, FAILs if a non-exempt .md lacks a Discourse URL. All projects.
 - Fixed CLI references (Q2) — AGENTS.md now documents the real container invocation paths (KNEL-AIMiddleware/{redmine,discourse}-cli/), not the missing bin/ shortcuts.
