feat: merge AI / Cloud / HomeLab into Tech pill with sub-sections

- Removed AI, Cloud, HomeLab as top-level pills
- Tech pill now matches all their slugs (ai, ml, cloud, homelab, security, dev)
- Tech view shows a sectioned front page: AI · Cloud · HomeLab · Security · Dev · Technology
- Sub-sections defined via NewsSection.techSubSections + StoryPill.subSections
- digest() extracted to makeDigest(sections:) so any pill can have sections
- Tech auto-loads 100 stories to fill its sub-sections (same as All)
- "All" Tech section in the main feed now links to Tech pill
