Extract entity card builder and sentiments into cards module

Acceptance Criteria

• New file runes/plan/src/cards.ts exists
• cards.ts has zero imports from node:fs, node:path, or node:child_process
• cards.ts only depends on @markdoc/markdoc (pure JS) and @refrakt-md/types (type-only imports)
• buildEntityCard(entity) is exported and produces the same Tag structure as the current inline version
• buildDecisionEntry(entity) is exported and produces the same Tag structure
• buildMetaBadge(label, value, opts) is exported
• All seven sentiment maps are exported as named constants: WORK_STATUS_SENTIMENT, BUG_STATUS_SENTIMENT, PRIORITY_SENTIMENT, SEVERITY_SENTIMENT, SPEC_STATUS_SENTIMENT, DECISION_STATUS_SENTIMENT, MILESTONE_STATUS_SENTIMENT
• Pipeline imports card builders and sentiments from ./cards.js instead of defining them inline
• All existing backlog, decision-log, and relationship rendering produces identical output
• Existing tests pass without modification

Approach

1. Create cards.ts. Move the seven sentiment map constants, buildMetaBadge(), buildEntityCard(), and buildDecisionEntry() from pipeline.ts.
2. The card builders use EntityRegistration from @refrakt-md/types for the entity parameter type and Tag from @markdoc/markdoc for constructing renderables — both are pure, edge-safe dependencies.
3. In pipeline.ts, replace the moved code with: import { buildEntityCard, buildDecisionEntry, buildMetaBadge, WORK_STATUS_SENTIMENT, ... } from './cards.js'.
4. Verify that pipeline.ts no longer defines any sentiment maps or card builder functions.
5. Run existing tests to confirm no regressions.

Dependencies

None — independent of other extractions.

What was done

• Created runes/plan/src/cards.ts with buildEntityCard, buildDecisionEntry, buildMetaBadge and all 7 sentiment maps
• Pipeline.ts now imports only buildEntityCard and buildDecisionEntry from cards.ts (sentiment maps are used internally by the card builders)
• Removed ~150 lines of inline card/sentiment code from pipeline.ts

Notes

• cards.ts depends only on @markdoc/markdoc (pure JS) and @refrakt-md/types (type-only import for EntityRegistration)
• All backlog, decision-log, and relationship rendering tests pass — output is identical
