feat: bootstrap meta — cross-project best-practices template

Extract patterns from 18 projects across two machines (12 local infra +
6 remote personal/business via ssh survey). Ship a reusable Gitea template
with AGENTS.md, 5 Crush PreToolUse hooks, git pre-commit/pre-push, a
generalized rules engine, shared bash library, Makefile, lifecycle scripts,
and gardening loop. Includes the canonical BASELINE-PROMPT.md (13 sections)
and PATTERNS.md (standardization scorecard).

The repo self-applies: it passes its own shellcheck (zero info-level),
make fast, and all check-rules.sh checks.

+# Makefile — the single standard task-entry surface for this project.
+#
+# Every project using the template exposes the SAME targets, so CI, hooks,
+# and humans all know one set of verbs regardless of the underlying stack.
+# Each target delegates to scripts/ so the logic is shellcheck-able and
+# runnable anywhere (the Makefile is pure dispatch).
+#
+# Targets:
+#   make setup    install git hooks (idempotent)
+#   make validate run the full rule audit
+#   make fast     run the fast rule audit (pre-commit equivalent)
+#   make lint     lint (shellcheck via docker)
+#   make test     run the test suite  <-- override for your stack
+#   make garden   doc-sprawl / Discourse-migration report
+#   make up       bring up the docker-compose stack
+#   make down     bring it down
+#   make status   show repo status snapshot
+#   make clean    remove build/test artifacts  <-- override for your stack
+#
+# Override `test` and `clean` per project; the rest are stable.
