Unified slash-command registry.
Every slash command is declared once as a SlashCommand entry in COMMANDS.
Bypass-tier frozensets and autocomplete entries are derived automatically — no
other file should hard-code command metadata.
All slash commands.
Commands that execute regardless of any busy state.
Commands that bypass only during initial server connection.
Commands that open modal UI immediately, deferring real work.
Commands whose side effect fires immediately; chat output deferred until idle.
Commands that must wait in the queue when the app is busy.
Hidden debug commands not exposed in autocomplete or help.
Union of all tiers plus hidden debug commands — used by drift tests.
Autocomplete entries derived from COMMANDS for SlashCommandController.
Extract skill name and args from a /skill:<name> command.
Build autocomplete entries for discovered skills.
Each skill becomes a /skill:<name> entry with its description
and the skill name as a hidden keyword for fuzzy matching.
Skills that already have a dedicated slash command in COMMANDS
(e.g., remember → /remember) are excluded to avoid duplicate
autocomplete entries.
Extended skill metadata for CLI display, adds source tracking.
Classification that controls whether a command can skip the message queue.
A single slash-command definition.
A single autocomplete entry for the slash-command controller.
