chore: release markform v0.1.28

[jlevy]

What's Changed

Features

• Fill observability and signal propagation: Added comprehensive observability for fillForm() operations with signal propagation to generateText() for proper cancellation, extended onLlmCallEnd callbacks with duration and provider metadata, LLM call details in timeline entries, structured error classification (errorType/errorCode), and raw event logs for debugging (feat: fill harness observability and signal propagation (#157) #158)
• FillRecord source-of-truth enrichment: Transform FillRecord into comprehensive source of record with provenance tracking (markform version, input hash, schema version), effective config snapshot, per-turn enrichment (form progress, rejection details, issue refs), and opt-in raw patches via --record-patches flag (feat: FillRecord source-of-truth enrichment with provenance and per-turn detail #161)
• External retry control: Expose maxRetries in FillOptions to allow production harnesses to disable hidden AI SDK retries and manage retries externally with full observability (feat: expose maxRetries in FillOptions for external retry control #162)
• Table row validation improvements: Drop fully-empty table rows during normalization, warn on sparse rows (>50% empty cells), strengthen minRows validation, and add defensive handling of unknown cell states (feat: FillRecord source-of-truth enrichment with provenance and per-turn detail #161, fix: table row validation improvements and defensive coding #163)

Fixes

• Fixed signal propagation bug where FillOptions.signal wasn't reaching generateText(), preventing cancellation of in-flight LLM calls (feat: fill harness observability and signal propagation (#157) #158)
• Fixed onLlmCallEnd callback to fire on failure (timeout, rate limit, network error), not just success, eliminating orphaned pending call entries (feat: fill harness observability and signal propagation (#157) #158)
• Fixed isRowFullyEmpty() to defensively treat unknown/malformed cell states as NOT empty, avoiding accidental data loss (fix: table row validation improvements and defensive coding #163)
• Fixed aborted table row handling to preserve aborted cells since they carry intentional agent signal (feat: FillRecord source-of-truth enrichment with provenance and per-turn detail #161)

Refactoring

• Extracted shared isCellEmpty() helper to eliminate duplication between row normalization and validation (fix: table row validation improvements and defensive coding #163)
