Add best-practices library, knowledge distillation pipeline settings, and first session log

- best-practices/: 11 topic files + INDEX.md extracted from cluster-bootstrap
  and custom-claude-skills (validation, k8s, helm, ansible, secrets, debugging, etc.)
- settings.yaml: pipeline config (log retention, tracked projects, max logs per run)
- CLAUDE.md: updated with best-practices loading and pipeline documentation
- memory/log/: first session log demonstrating the format

+# Documentation Standards
+
+Every project maintains four core markdown files.
+
+## CLAUDE.md
+
+The primary reference for Claude sessions. Should contain:
+- Project overview and architecture
+- Repository structure (keep updated as the project evolves)
+- Key design decisions with rationale
+- Conventions and coding standards
+- Environment details (IPs, URLs, credential references — never actual values)
+- Common operations / how-to recipes
+- Put critical rules at the top — Claude reads sequentially and earlier content has more influence
+
+## MEMORY.md (Tiered Memory System)
+
+Long-running projects accumulate significant context. Use a **tiered memory** structure:
+
+**MEMORY.md** is a **thin index only** — one-line descriptions with links to topic files in `memory/`. No content lives in MEMORY.md itself. Keep it under ~50 lines.
+
+**memory/** contains the actual content, split by topic:
+- `memory/project-status.md` — Current milestone, what's next, blockers
+- `memory/gotchas-<topic>.md` — Gotchas grouped by technology
+- `memory/process-lessons.md` — How-to-work-with-this-repo lessons
+- `memory/m<N>-reflection.md` — One file per milestone reflection
+- `memory/decisions.md` — Architecture and design decisions
+
+**Principles:**
+- Split by topic, not by time
+- Index descriptions matter — they're used to decide what to read
+- Prune aggressively — stale memory is worse than no memory
+- Each file should be self-contained and greppable
+- Deduplicate with CLAUDE.md — stable conventions go in CLAUDE.md, learnings and gotchas go in memory
+
+## FUTURE.md
+
+Backlog of improvement ideas, each with:
+- **Problem:** What's painful or manual today
+- **Idea:** What the improvement looks like
+- **Open questions:** Unknowns to research before starting
+- **Depends on:** Other items or milestones that should come first
+
+## README.md
+
+Human-readable project documentation:
+- Architecture summary
+- Quick start / setup instructions
+- Milestone table with status
+- Scripts section listing every script with purpose and usage
