Collapses chat-family sessions per Qor into a single canonical chat row.Use this once after upgrading past the one-Qor-one-chat refactor.Subsequent chat-family writes already route to the canonical session,so this only needs to run against databases with historical fan-out.Archives old rows rather than deleting them; drop the archive lateronce you're confident nothing depends on their ids.Usage: qorven collapse-sessions [flags]Examples: qorven collapse-sessions --dry-run qorven collapse-sessions --yesFlags: --dry-run print what would change without writing -h, --help help for collapse-sessions --yes skip interactive confirmationGlobal Flags: -o, --output string Output format: table, json, yaml (default "table") --server string Gateway URL (env: QORVEN_SERVER) --token string Auth token (env: QORVEN_TOKEN) -v, --verbose Verbose output
