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.
