v0.2.2

Added

• --catalog json — machine-readable flag inventory. Same shape across the three-CLI suite (matching sign --catalog json and nda-review-cli --catalog json). Agents call this at startup rather than parsing --help. Stable across minor versions.
• --retries <n> flag for network backends (gotenberg, convertapi) to retry transient failures in a controlled way.
• JSON success telemetry now includes outputBytes and durationMs for easier automation, observability, and benchmarking.
• Capability payload (docx2pdf --capabilities) now advertises retry support via supports.retries.
• AGENTS.md as the canonical agent entry point — replaces the prior docs/AGENT_INTEGRATION.md (merged). Documents the output contract, exit-code map, discovery commands, recommended defaults, fallback policy, and a failure-mode → recovery table.
• docs/setup/ per-backend pages for libreoffice, gotenberg, convertapi, pages, and word.
• docs/reference/ — canonical homes for backends, doctor JSON shape, exit codes, and JSON/NDJSON output. Concept docs that previously lived inline in the README.
• schemas/doctor.schema.json — formal JSON schema for the --doctor output (was previously documented only by example).

Changed

• Retry backoff implementation now uses non-busy synchronous wait (Atomics.wait) to avoid CPU spin during retry delays.
• Parallel JSON mode now preserves full child success telemetry fields instead of collapsing to a minimal shape.
• Test suite skips the --json success-telemetry test when LibreOffice is unavailable (same pattern as the existing smoke test). Fixes macOS CI runs.
• README restructured around audience: "Run this" (docx2pdf --doctor) → "Where to go next" decision tree → human quickstart → backends overview → diagnostics → agent affordances. Human path now precedes the agent section.

Removed

• docs/AGENT_INTEGRATION.md (merged into top-level AGENTS.md — 87-line duplication eliminated).
