docs(README): index the contributor docs the launch reader needs

The index covered users, architecture and app development but had no entry
point for "I want to work on Archipelago itself" — so eight tracked docs were
reachable only by guessing filenames, including the two that matter most to a
newcomer: developer-guide.md (how to build the workspace, the frontend and an
ISO) and LICENSE-COMPLIANCE-AUDIT.md (dependency licensing, which is exactly
what a reader checks first on an open-source repo).

Added a "Contributing to Archipelago itself" section covering those plus
bulletproof-containers, the signing runbook, the 1.8.0 hardening plan and
CLAUDE.md; filed pine-voice-commands under Getting started and demo-build-info
under contributing.

Also noted that ADR-010 was never issued — verified across all history, so the
009 → 011 gap is not a missing file — and added the two archived session logs
(HANDOVER-2026-07-02, SESSION-1.8.0-OTA-PROGRESS) to the archive table, which
already claimed to cover completed session logs but listed none.

Link check re-run across docs/: 0 broken. Only RELEASE_NOTES_BACKLOG.md is now
deliberately unindexed (internal working list).
