- Add brew_time INTEGER column to brews table (nullable, stored as seconds)
- Display as M:SS format with stepper control (+/-5s) in add form
- Replace ratio with brew time in brew list Recipe column
- Show brew time in brew cards and timeline events
- Add --brew-time CLI flag and update bootstrap script (1:45-2:45 range)
Without AUTOINCREMENT, SQLite can reassign the highest deleted ROWID to
a new row. This is a data integrity bug: a deleted entity's ID could be
assigned to a completely different entity, breaking bookmarks, API
caches, and URL stability.
No production instances exist, so safe to rewrite from scratch.
Drops columns that were added then removed (notes, password_hash,
cup rating), standardises timestamp format and primary key style,
and creates all tables in their final form without incremental
ALTER TABLE churn.
