v0.2.0

• much faster sync --full behavior on large archives: incomplete backfills are auto-batched, active-thread discovery is more precise, and steady-state refreshes avoid re-scanning every archived thread once history is already complete
• sync --since now reliably honors the cutoff during bootstrap and full-history backfill, while still allowing a later sync --full without --since to continue older history
• full-sync progress is more resilient: slow member crawls no longer hold message sync hostage, and stale unavailable-channel markers are cleared so recovered channels can sync again
• offline member-profile search is now much richer: members search matches archived profile fields in addition to names
• members show now accepts either Discord IDs or queries and can include recent messages plus message stats for the resolved member
• archived profile extraction now surfaces stored fields like bio, pronouns, location, website, x, github, and discovered URLs when present
• messages --sync can do a blocking pre-query refresh for the matching channel or guild scope before reading the local archive
• messages --hours adds recent-hour slices without manual RFC3339 timestamps
• messages --last returns the newest matching rows while still printing them oldest-to-newest
