Loading this cog called bot.remove_command("help") with no replacement
command ever defined and no restore on unload — simply loading it broke
[p]help bot-wide, permanently, until process restart. Traced through Red's
own source (redbot/core/commands/help.py) and confirmed the default help
command already routes through bot.send_help_for(), which is exactly what
this cog hooks to render CV2 output — so the fix is to just not remove the
command at all; the CV2 conversion now actually works as intended too,
since its hook point is reachable again.
_active_views leaked one permanent dict entry (holding the whole rendered
page/embed list) per help/menu invocation — every on_timeout and "close"
button already called view.stop(), but nothing was popping the matching
entry except one specific code path. Added a single _track_view() helper
that wraps stop() for automatic eviction and applied it at all 5 insertion
points instead of just the one.
Parallelized the per-command can_run() permission checks in
gather_bot_help_data/gather_cog_help_data (previously one await at a time
for every bot/cog command on every single [p]help call). Also added the
admin_or_permissions check to `cv2 version`, the one subcommand missing it.
