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.

+# Reports doc sprawl and files that violate the "Discourse is the system of
+# record for documentation; gitea .md files are stubs" policy. Run via
+# `make garden`. Findings are WARNINGS (advisory); fix them at a natural break.
+#
+# What it checks:
+#   1. Markdown sprawl: count of .md files per directory (top-10 by count).
+#   2. Oversized .md files (default >300 lines) that don't cite a Discourse URL
+#      — candidates to migrate to Discourse, leaving a stub.
+#   3. .md files with no Discourse link at all (informational; exempt: the
+#      operational files in EXEMPT_FILES).
