v0.5.1

[0.5.1] - 2026-04-10

Added

• feat: data export — sonar data export --format json --window 1d for bulk suggestion/bookmark/like export with cursor pagination.
• feat: X API rate limit handling — detect 429s explicitly with retry guidance.

Changed

• refactor: migrate CLI from Pastel to Commander + Ink — faster startup, better arg parsing, composable subcommands.
• refactor: extract parseWindow to lib/time — shared time window parsing across commands.
• refactor: add analysis helpers to lib/ai — structured OpenAI/Anthropic analysis calls for upcoming lens commands.

Fixed

• fix: use structured outputs for LLM response parsing — replaces fragile regex with JSON schema validation.
• fix: client-side input validation — topic names and descriptions validated before API call.
