Fix SEO skills 19-34 bugs, add slash commands, enhance reference-curator (#3)

* Fix SEO skill 34 bugs, Korean labels, and transition Ahrefs refs to our-seo-agent

P0: Fix report_aggregator.py — wrong SKILL_REGISTRY[33] mapping, missing
CATEGORY_WEIGHTS for 7 categories, and break bug in health score parsing
that exited loop even on parse failure.

P1: Remove VIEW tab references from skill 20, expand skill 32 docs,
replace Ahrefs MCP references across all 16 skills (19-28, 31-34)
with our-seo-agent CLI data source references.

P2: Fix Korean labels in executive_report.py and dashboard_generator.py,
add tenacity to base requirements, sync skill 34 base_client.py with
canonical version from skill 12.

* Add Claude Code slash commands for SEO skills 19-34 and fix stale paths

Create 14 new slash command files for skills 19-28, 31-34 so they
appear as /seo-* commands in Claude Code. Also fix stale directory
paths in 8 existing commands (skills 12-18, 29-30) that referenced
pre-renumbering skill directories.

Update .gitignore to track .claude/commands/ while keeping other
.claude/ files ignored.

+
+# NotebookLM Research
+
+Research workflows: web research, Drive search, auto-import, source extraction.
+
+## Prerequisites
+
+```bash
+pip install notebooklm-py
+playwright install chromium
+notebooklm login
+```
+
+## Research Commands
+
+```bash
+# Web research
+notebooklm source add-research "topic"
+notebooklm source add-research "topic" --mode deep --import-all
+notebooklm source add-research "topic" --mode deep --no-wait
+
+# Drive research
+notebooklm source add-research "topic" --from drive
+
+# Status and wait
+notebooklm research status
+notebooklm research wait --import-all
+```
+
+## Source Extraction
+
+```bash
+notebooklm source fulltext <id>
+notebooklm source guide <id>
+```
+
+## Research Modes
+
+| Mode | Sources | Time |
+|------|---------|------|
+| `fast` | 5-10 | seconds |
+| `deep` | 20+ | 2-5 min |
+
+## Subagent Pattern
+
+```python
+# Non-blocking deep research
+notebooklm source add-research "topic" --mode deep --no-wait
+
+# Spawn subagent to wait
+Task(
+  prompt="Wait for research and import: notebooklm research wait -n {id} --import-all",
+  subagent_type="general-purpose"
+)
+```
+
+## Autonomy
+
+**Auto-run:** `research status`, `source fulltext`, `source guide`
+**Ask first:** `source add-research`, `research wait --import-all`
