This commit changes our linter/formatter to biome (https://biomejs.dev/)
Causing our prehook to run almost instantly, and our "yarn lint" task to
run in sub 100ms.
Some trade-offs:
* Biome isn't quite as well established as ESLint
* Are we ready to install a different vscode plugin (the biome plugin)
instead of the prettier plugin
The configuration set for biome also has a set of recommended rules,
this is turned on by default, in order to get to something that was
mergeable I have turned off a couple the rules we seemed to violate the
most, that we also explicitly told eslint to ignore.
## About the changes
Add partial index on events by announced. This should help avoid `Seq
Scan on events` when the majority of events are announced=true

## About the changes
When the events table is large we might be doing a full table scan
searching for unannounced events. We spotted it due to a performance
alert and confirmed in AWS performance insights

The proposal is to limit this operation to 500 events (rule of thumb)
per round
f82ae354eb/src/lib/services/index.ts (L141-L147)
and also ignore the events older than a day (because it seems
reasonable)
## Discussion points
**Idea**: split the `events` table into `recent_events` and
`historical_events`. Recent can be anything from a day/week/month. This
would help with recurrent queries that rely on recent data from the
event's table such as optimal 304 calculation or event this scheduled
task that sends unannounced events.
