Let the operator add aliases from the Commands tab
A custom alias is data the command table is built from, so it cannot be a
live switch like the ones already on the tab. Instead the management page
writes aliases_custom.json in the bot's state directory and then asks the
bot to reload, in one step: whenever the answer is anything but `reloaded`
-- a word another command has, a name no command has, a bot still
connecting -- the file is restored byte for byte and the bot's own reason is
shown next to the field. What is on disk is therefore always what the bot
serves, and a typo cannot sit in the file poisoning every later reload.

The registry appends the operator's words to the shipped list at
registration, which keeps `!pomoc` on the shipped spelling and routes the
new words through the same clash check as aliases.json. An alias for a name
no command has fails the whole build (ConfigError -> `kept`), because a
silently ignored entry is how a file drifts. The tagger treats custom
aliases as reserved words too, so a person cannot be given one.

registry.py crossed the 250-line cap and now re-exports the record and the
error types from command.py; the bot's state directory lookup, previously
duplicated in pack.py and the suggestions export, is state_dir.py.

Proven end to end: !e2ekot is unknown, the file is written and reload.sh
runs, !e2ekot posts a cat, a file naming a command that does not exist is
refused with 409 and the previous table still answers.
