User requested dynamic (not static) fields for CTF writeup content organization.
Changes:
- DocumentMeta: removed typed CTF fields (event/challenge/category/difficulty/
points), replaced with single extraFields?: Record<string, string>
- parseFile: any frontmatter key not in the STANDARD set becomes a dynamic
extra field — fully content-driven, no code changes needed for new fields
- stringifyFile: writes extraFields back to YAML frontmatter for round-trip
stability
- DocForm: '+ Add field' UI lets creators add ANY metadata key at create/edit
time
- API routes: splitPayload() auto-separates standard vs custom fields
- Doc page: CustomFieldBadges dynamically renders any custom field with
auto-styling for common CTF patterns (difficulty→color, points→badge)
- Added db:migrate + db:push scripts; deploy workflow now runs migrations +
reindexes content on every deploy
- content/writeups/ctf/template/writeup-template.md (template)
- content/writeups/ctf/defcon-quals-2024/pwn-100-ret2win-alignment.md (sample)
- DB column extra_fields (jsonb) already applied to live DB
