rename: memorize → codify

"memorize" implied passive storage (same mental model as auto-memory).
"codify" captures the actual operation: editorial selection, specific
phrasing, deliberate commit to a lasting artifact.

Changes:
- memorize/ → codify/
- SKILL.md: name: codify; title updated; all references changed
- Default CLAUDE.md section: ## Memorized Insights → ## Codified Insights
- Makefile SKILLS updated
- Old ~/.claude/skills/memorize symlink removed; codify symlink created

-name: memorize
-description: Curate concrete, actionable insights into the project's `CLAUDE.md` so they survive across sessions and compound over time. Harvests recent-session learnings (patterns that worked, anti-patterns that bit, API gotchas, verification checks), filters against quality gates (atomic, evidence-backed, non-redundant, verifiable, safe), and writes into a dedicated `## Memorized Insights` section rather than scattering entries. Use after a productive session, a bug fix that revealed a non-obvious pattern, or an explicit review where you want learnings preserved. Supports `--dry-run` to preview, `--max=N` to cap output, `--target=<path>` to write elsewhere, `--section=<name>` to override the destination section. Flags insights that look cross-project and suggests promotion to `~/code/rulesets/claude-rules/` instead. Do NOT use for session wrap-up / progress summaries (not insights), for private personal context (auto-memory handles that, not a tracked file), or for rules that belong in a formal rules file (those go under `.claude/rules/`).
