Useful in moderation scenarios where you want to quarantine media and can quickly/easily look at the data attribute on the media (image/videos). Or simply write a little script to extract all of the `data-mxc-url` and `data-thumbnail-mxc-url` attributes.
ex.
```
<img src="http://localhost:8008/_matrix/media/r0/thumbnail/my.synapse.server/TEyTVUNgvUQZcXlrLwgGfbcp?width=400&height=266&method=scale" alt="Stormclouds.jpg" title="Stormclouds.jpg" data-mxc-url="mxc://my.synapse.server/kxibKhxRfTvFWyuWwWvFuBtE" data-thumbnail-mxc-url="mxc://my.synapse.server/TEyTVUNgvUQZcXlrLwgGfbcp" style="max-width: 400px; max-height: 266px;">
```
- Rename `public` -> `client` so it doesn't get copied automagically as-is (without hashes which we want for cache busting), https://vitejs.dev/guide/assets.html#the-public-directory
- We still build the version files to `public/` so their copied as-is and Vite handles it for us (so we can use `emptyOutDir`)
- Use a multiple entrypoint `.js` Vite build so things can be more intelligently bundled and take less time
- We aren't using library mode because it doesn't minify or bundle assets
- Using hash asset tags for cache busting. Hash of the file included in the file name
- We lookup these hashed assets from `manifest.json` that Vite builds (https://vitejs.dev/guide/backend-integration.html) to serve and preload
- In terms of optimized bundles, I know the current output isn't great now but will have to opt to fix that up separately in the future. Tracked by https://github.com/matrix-org/matrix-public-archive/issues/176

Other updates:
- Update tests to use `/roomid/room1/date/2022/01/03` format instead of trying to retrofit the weird alias stuff on there. Which also makes the fancy to actual URL utilities much more simple.
- Update to specify `archiveMessageLimit` in the test case because pages have different number of events depending on if we are against a boundary, hidden events, etc.
`"no-unused-vars": ["error", { "destructuredArrayIgnorePattern": "^_" }],` was only [introduced in `eslint@8.11.0`](0fd6bb213a/CHANGELOG.md) so we had to update
This change enables CORS support in the archive — to allow web developers to create web applications with frontend JavaScript code that can fetch pages from the archive (for example, for scraping content from chat logs).
Otherwise, without this change, web developers can’t create web apps with frontend JavaScript that can fetch chat logs from the archive and then consume the content of the logs.
It’s imaginable that web developers may find use cases for consuming the chat logs in the archive from frontend JavaScript code — at the simplest level, web apps that fetch and scrape logs to get data out of them or to pull out particular snippets from the logs.
Developers can anyway already scrape the contents of the archive — by using server-side programming languages or by using `curl` or whatever from the command line. They just can’t do the same from frontend JavaScript code, unless CORS support is enabled.
This might be a little ambiguous since we'll have permalinks within the Matrix Public Archive with `?at=$xxx` (related https://github.com/matrix-org/matrix-public-archive/issues/137) which is different from `matrix.to` permalinks 🤔
But will just go with it for now ⏩

Follow-up to https://github.com/matrix-org/matrix-public-archive/pull/71
Summary:
- Changes the "Jump to next activity in room" to actually continue you to the next 100 messages ahead. Previously, it only jumped you to the single next event in the room which meant a lot of backwards overlap each time.
- Jumping this direction will also start your scroll position at the top of the timeline to continue reading seamlessly `?continue=top`
- Adds "Jump to previous activity in room" to the top of the timeline to continue reading the previous part of the conversation.
[1]: There is a caveat with seamless here which is also commented on in the code:
> XXX: This is flawed in the fact that when we go `/messages?dir=b` it could backfill messages which will fill up the response before we perfectly connect and continue from the position they were jumping from before. When `/messages?dir=f` backfills, we won't have this problem anymore because any messages backfilled in the forwards direction would be picked up the same going backwards.
(need forwards fill MSC)
Also does friendly redirects if you don't exactly use the right URL pattern.
For example, if you paste the full room ID with the `!` like `/roomid/!foo:bar`,
it will properly redirect you to `/roomid/foo:bar`. It also does this sort of
thing for URL encoded room ID's and aliases.

Page-load with the correct homeserver selected (according to `?homeserver`).
Fix https://github.com/matrix-org/matrix-public-archive/issues/92
Also makes sure that the `?homeserver` is always available somewhere in the list; whether that be in the available homeserver list or the added homeserver list depending on it someone cleared it out or never had it because they visited from someone else's link.
1. Add surrounding messages to the given messages so we have a full screen of content to make it feel lively even in quiet rooms
- As you scroll around the timeline across different days, the date changes in the URL, calendar, etc
2. Add summary item to the bottom of the timeline that explains if we couldn't find any messages in the specific day requested
- Also allows you to the jump to the next activity in the room. Adds `/:roomId/jump?ts=xxx&dir=[f|b]` to facilitate this.
- Part of https://github.com/matrix-org/matrix-public-archive/issues/46
3. Add developer options modal which is linked from the bottom of the right-panel
- Adds an option so you can debug the `IntersectionObserver` and how it's selecting the active day from the top-edge of the scroll viewport.
- In the future, this will also include a nice little visualization of the backend timing traces
Fix missing `room.observePowerLevels()` throwing error after render.
```
Uncaught (in promise) TypeError: this._room.observePowerLevels is not a function
at RoomViewModel2._recreateComposerOnPowerLevelChange (matrix-public-archive.js:23498:53)
at new RoomViewModel2 (matrix-public-archive.js:23469:14)
at mountHydrogen (matrix-public-archive.js:27131:25)

```
Doesn't affect main-line rendering but the error is annoying to see. More Hydrogen boilerplate 😞
Use `DisabledComposerView` instead of no composer to add message:
> You're viewing an archive of events from 2022-02-08. Use a [Matrix client](https://matrix.to/#/!HBehERstyQBxyJDLfR:my.synapse.server) to start chatting in this room.
Also refactors some of the `views` and `viewmodels` out to their own files
OpenTelemetry tracing so we can see spans where the app is taking time.
For the user, we specifically show the spans for the external API HTTP requests
that are slow (so we know when the Matrix API is being slow).
Enable tracing:
- `npm run start -- --tracing`
- `npm run start-dev -- --tracing`
What does this PR change:
- Adds OpenTelemetry tracing with some of the automatic instrumentation (includes HTTP and express)
- We ignore traces for serving static assets (just noise)
- Adds `X-Trace-Id` to the response headers
- Adds `window.tracingSpansForRequest` which includes the external HTTP API requests made during the request
- Adds a fancy 504 timeout page that includes trace details and lists the slow HTTP requests
- Adds `jaegerTracesEndpoint` configuration to export tracing spans to Jaeger
- Related to, https://github.com/matrix-org/matrix-public-archive/issues/26
1. Build test homeserver Docker images which can federate with each other
2. Run end-to-end (e2e) tests
#### Dev notes
Sharing variables across jobs when the `services` field can't access the `env` context, https://github.community/t/how-to-use-env-with-container-image/17252/24
```yaml
env:
FOO: bar
jobs:
set_env:
outputs:
var: ${{ steps.save_var.outputs.var }}
steps:
- id: save_var
run: echo "::set-output name=var::${{ env.FOO }}"
actual_job:
needs: set_env
container:
image: ...whatever_you_need_here...${{ needs.set_env.outputs.var }}
```
Remove `matrix-bot-sdk` usage in tests because it didn't have timestamp massaging `?ts` and it's not really necessary to rely on since we can just call the API directly 🤷. `matrix-bot-sdk` is also very annoying having to build rust crypto packages.
We're now using direct `fetch` requests against the Matrix API and lightweight `client` object.
All 3 current tests pass ✅
Get this project running again after a few months of changes
from `hydrogen-view-sdk` and now finally after
https://github.com/vector-im/hydrogen-web/pull/693
merged to make the SDK friendly to locally link and develop on.
