FIX: Don't update url in GitImporter (#19273)

FIX: When following redirects before cloning, use the first git request (#19269)
This is closer to git's redirect following behaviour. We prevented git
following redirects when we clone in order to prevent SSRF attacks.

FIX: When cloning themes via HTTP, try the original URI too (#18870)
This should fix fetching from gitlab.

In order to get SSRF protection, we had to prevent redirects when cloning via git, but some repos are behind redirects and we want to support those too. We use `FinalDestination` before cloning to try to simulate git with redirects, but this isn't quite how git works, so there's some discrepancies between our SSRF protected cloning behavior and normal git behavior that I'm trying to work around.

This is temporary fix. It would be better to use `FinalDestination` to simulate the first request that git makes. I aim to make it work like that in the not too distant future, but this is better for now.

FEATURE: allow for local theme js assets (#16374)
Due to default CSP web workers instantiated from CDN based assets are still
treated as "same-origin" meaning that we had no way of safely instansiating
a web worker from a theme.

This limits the theme system and adds the arbitrary restriction that WASM
based components can not be safely used.

To resolve this limitation all js assets in about.json are also cached on
local domain.

{
  "name": "Header Icons",
  "assets" : {
    "worker" : "assets/worker.js"
  }
}

This can then be referenced in JS via:

settings.theme_uploads_local.worker

local_js_assets are unconditionally served from the site directly and
bypass the entire CDN, using the pre-existing JavascriptCache

Previous to this change this code was completely dormant on sites which
used s3 based uploads, this reuses the very well tested and cached asset
system on s3 based sites.

Note, when creating local_js_assets it is highly recommended to keep the
assets lean and keep all the heavy working in CDN based assets. For example
wasm files can still live on the CDN but the lean worker that loads it can
live on local.

This change unlocks wasm in theme components, so wasm is now also allowed
in `theme_authorized_extensions`

* more usages of upload.content

* add a specific test for upload.content

* Adjust logic to ensure that after upgrades we still get a cached local js
on save

PERF: Add timeout to theme import git commands (#12856)
This ensures that large git repositories cannot cause performance issues on the server. In normal use, this 20s timeout should never be hit.

PERF: Improve theme stylesheet compilation performance (#12850)
When building the `scss_load_paths`, we were creating a full export of the theme (including uploads), and not cleaning it up. With many uploads, this can be extremely slow (because it downloads every upload from S3), and the lack of cleanup could cause a disk to fill up over time.

This commit updates the ZipExporter to provide a `with_export_dir` API, which takes care of cleanup. It also adds a kwarg which allows exporting only extra_scss fields. This should make things much faster for themes with many uploads.

FIX: Gracefully handle force pushes for remote themes (#11325)
Force pushing a commit to a theme repository used to break the updater,
because the system was not able to count the commits behind the old and
new version. This operation failed because a force push deleted the old
commits.

The user was prompted with a simple "500 server error" message.

Jeff Wong 787ad7d84d FIX: allow plugin pinning to fetch missing commits

Support plugin and Theme compatibility version manifests (#9995)
Adds a new rake task `plugin:checkout_compatible_all` and
`plugin:checkout_compatible[plugin-name]` that check out compatible plugin
versions.

Supports a .discourse-compatibility file in the root of plugins and themes that
list out a plugin's compatibility with certain discourse versions:

eg: .discourse-compatibility
```
2.5.0.beta6: some-git-hash
2.4.4.beta4: some-git-tag
2.2.0: git-reference
```

This ensures older Discourse installs are able to find and install older
versions of plugins without intervention, through the manifest only.

It iterates through the versions in descending order. If the current Discourse
version matches an item in the manifest, it checks out the listed plugin target.
If the Discourse version is greater than an item in the manifest, it checks out
the next highest version listed in the manifest.

If no versions match, it makes no change.

FIX: don't break the private key when writing it out during theme import
* when importing a private theme using the themes:install rake task the SSH key is written out to a file for use by the git-clone command
* if the private key is written out without a newline at end-of-file (i.e. after it's been stripped) it's not recognized as a valid key by SSH
* so: don't strip it when writing it out, we should be fine

DEV: Remove use of `cd` in the app (#8337)
`FileUtils.cd` and `Dir.chdir` cause the working directory to change for the entire process. We run sidekiq jobs, hijacked requests and deferred jobs in threads, which can make working directory changes have unintended side-effects.

- Add a rubocop rule to warn about usage of Dir.chdir and FileUtils.cd
- Added rubocop:disable for scripts used outside the app
- Refactored code using cd to use alternative methods
- Temporarily skipped the rubocop check for lib/backup_restore. This will require more complex refactoring, so I will create a separate PR for review

Krzysztof Kotlarek 427d54b2b0 DEV: Upgrading Discourse to Zeitwerk (#8098)
Zeitwerk simplifies working with dependencies in dev and makes it easier reloading class chains. 

We no longer need to use Rails "require_dependency" anywhere and instead can just use standard 
Ruby patterns to require files.

This is a far reaching change and we expect some followups here.
