docs: add STATUS.md, docmap.md, encode gardening protocol

Restructure top-level to exactly three .md files:
- AGENTS.md (agent operating instructions)
- README.md (project overview, links to status + docmap)
- STATUS.md (living project status, agent-maintained, human read-only)

Add docs/docmap.md as the single documentation index/map. All docs are
categorized (active, operational guides, historical) with last-reviewed
dates. Includes the agent gardening protocol requiring agents to update
STATUS.md and docmap.md after every work session.

Rewrite AGENTS.md to be lean: points to docmap.md for doc discovery,
encodes the automatic gardening protocol (keep docs/code in sync, grep
for stale paths after renames, update STATUS.md after infrastructure
changes). All references are Gitea-renderable relative links.

Simplify README.md: header links to STATUS.md + docmap.md + AGENTS.md,
doc table replaced with pointer to docmap.md.

+## Agent Gardening Protocol
+
+When making changes to this repo, agents MUST:
+
+1. **Update [`../STATUS.md`](../STATUS.md)** if the work changes infrastructure
+   state, completes/starts a task, or discovers a new issue.
+2. **Update this file (`docmap.md`)** if a doc is added, removed, or has a
+   substantive content change. Update the "Last Reviewed" date.
+3. **Verify cross-references** — any new `.md` file must be linked from at
+   least one existing doc or this map.
+4. **Check for stale paths** — after any directory rename or file move,
+   grep all `.md` files for old paths and fix them.
+5. **Keep code and docs in sync** — if you change a script's interface,
+   behavior, or location, update every doc that references it in the same
+   commit.
