fix: create missing scripts/types/ TypeScript definitions and unblock from .gitignore

[Copilot]

npx tsc --project tsconfig.scripts.json --noEmit was failing with 80+ TS2307: Cannot find module './types/*.js' errors because the scripts/types/ directory was never committed — it was silently excluded by the types/ pattern in .gitignore.

Changes

.gitignore

• Added !scripts/types/ negation so the directory is tracked by git

scripts/types/ — new type definition files

File	Key exports
language.ts	Language (14-language union)
article.ts	ArticleData, ArticleType, ArticleCategory, GenerationResult, GeneratedArticle, MCPCallRecord, BreakingEventData, BreakingNewsOptions, BreakingNewsValidation
content.ts	BreadcrumbLabels, FooterLabelSet, ContentLabelSet, CommitteeNameMap
editorial.ts	EditorialPillar, PillarHeadings, LocalizedPillarHeadings
validation.ts	StructureValidation, EveningAnalysisValidation, QualityResult, CrossRefValidationResult, BatchValidationResult, CISummary, RequiredToolsMap
mcp.ts	MCPClientConfig, JsonRpcRequest/Response, search/filter param types, RiksdagDocument
workflow.ts	WorkflowState, MCPCacheEntry, RecentArticleEntry, DuplicateCheckResult, WorkflowRecord
party.ts	PartyCode, PartyVariantMap

Type fixes resolved alongside missing files

• QualityResult — optional fields to accommodate the early-error return path in article-quality-enhancer.ts
• RiksdagDocument — added dokumentnamn? and id? to fix '{}' not assignable to 'string' in mcp-client.ts
• MCPCallRecord.result typed as unknown (not unknown[]) to match fetchVotingRecords return
• ArticleType extended with 'breaking'; BreakingEventData/Options/Validation added to unblock news-types/breaking-news.ts and its tests
