Major rewrite of help rendering:
- Embed mode (default): Rich embeds with interactive View buttons
(⏮◀️▶️⏭) + category select dropdown + close button
- CV2 mode (when `cv2 toggle` is on): Components V2 containers
with the same navigation
- Shared data-gathering layer: both modes use the same logic to
gather commands, filter permissions, handle categories
- All Red help features: command filtering, permission checks,
aliases, subcommands, cooldowns, format_help_for_context
- Text fallback for DMs
- Help command now always tries CV2 in guilds (that's its purpose)
with text fallback only on error or in DMs
- cv2 group invoke no longer calls ctx.send_help() which relied
on Red's internal formatter — sends usage text directly
- Context.send calls Messageable.send internally, both patched —
use asyncio task ID set to prevent re-entry loop
- Text fallback for help now paginates at 1900 chars to stay
under Discord's 2000-char limit
The classic Red/discord.py pattern: bot.remove_command('help') in
__init__.py's setup() BEFORE bot.add_cog(), so the cog's own
@commands.command(name='help') decorator doesn't clash with Red's
built-in help.
Original help command stored on cog instance and restored in cog_unload.
- Removes Red's built-in help command on cog load, restores on unload
- Our help command fully replaces it (CV2 when enabled, text fallback for DMs)
- Monkey-patches both Context.send AND Messageable.send so ALL bot embeds
everywhere (channels, threads, DMs) get auto-converted to CV2 containers
- Per-cog overrides still respected for Context sends
- Clean restore of everything on cog unload
Replaces embed-based help with full Components V2 system:
- converter.py: Embed → Container conversion engine
- formatter.py: CV2 help page builder + paginator views
- newhelpmenu.py: Main cog with settings, monkey-patching, public API
- 1,747 lines across 4 files, default off
