Comment excerpts in activity feeds previously used either the first 200
display characters of a comment or, for review comments, its first
physical line. That excerpt is rendered as Markdown in the feed, so if
the excerpt began with a leading blank lines or structural markdown
syntax, the excerpt would render as empty or produce broken output. For
example, a review comment beginning with a code fence stored only the
opening fence, which rendered as an empty code block.
This commit instead renders feed excerpts as prose only, dropping code,
math, tables, images and HTML, which also fixes already stored excerpts.
New excerpts start at the first prose line, and review comments get the
same excerpt as issue comments.
This produces meaningful excerpts in more cases while preserving their
original Markdown.

For a comment that contains the following:
````
```
some code
```
hello
````
This previously rendered as:
<img width="816" height="118" alt="Screenshot 2026-09-08 at 5 06 47 PM"
src="https://github.com/user-attachments/assets/9d125363-72de-46bf-b47a-961245a79c5f"
/>
And now renders as:
<img width="807" height="89" alt="Screenshot 2026-09-08 at 5 08 30 PM"
src="https://github.com/user-attachments/assets/d2dcdc6d-d7a9-437f-8e9c-b845fe99fa5e"
/>

1. add missing CSP header to api & web render endpoints.
2. make jupyter render skip post-processors, nothing to process
3. make ShortLinkProcessor correctly validate URL schemes and respect
the CustomURLSchemes setting
In dev mode `/api/swagger` returned HTTP 500 (`Failed to locate local
path for managed asset URI: css/swagger.css`): the backend synthesised
asset keys from the Vite entry name instead of reading the manifest,
which only worked by coincidence and broke once a source file name
diverged from its entry name.
This keys the manifest by its source path (e.g. `web_src/js/index.ts`)
and resolves entries directly — hashed `file` in prod, dev-server source
in dev. A new `AssetCSSLinks` helper renders a JS entry's stylesheet
`<link>` tags from the manifest (the entry's CSS plus the CSS of its
statically-imported chunks).

Introduces a frontend external-render framework that runs renderer
plugins inside an `iframe` (loaded via `srcdoc` to keep the CSP
`sandbox` directive working without origin-related console noise), and
migrates the 3D viewer and OpenAPI/Swagger renderers onto it. PDF and
asciicast paths are refactored to share the same `data-render-name`
mechanism.
Adds e2e coverage for 3D, PDF, asciicast and OpenAPI render paths, plus
a regression for the `RefTypeNameSubURL` double-escape on non-ASCII
branch names.

Keep `swagger` and `external-render-helper` as a standalone entries for
external render.
- Move `devtest.ts` to `modules/` as init functions
- Make external renders correctly load its helper JS and Gitea's current theme
- Make external render iframe inherit Gitea's iframe's background color to avoid flicker
- Add e2e tests for external render and OpenAPI iframe

Replace webpack with Vite 8 as the frontend bundler. Frontend build is
around 3-4 times faster than before. Will work on all platforms
including riscv64 (via wasm).
`iife.js` is a classic render-blocking script in `<head>` (handles web
components/early DOM setup). `index.js` is loaded as a `type="module"`
script in the footer. All other JS chunks are also module scripts
(supported in all browsers since 2018).
Entry filenames are content-hashed (e.g. `index.C6Z2MRVQ.js`) and
resolved at runtime via the Vite manifest, eliminating the `?v=` cache
busting (which was unreliable in some scenarios like vscode dev build).

This PR fixes#27383 where HTML headings like `<h1>Title</h1>` in
markdown files would have empty permalink anchors

* Fix#33972
* Use consistent path resolving for links and medias.
* No need to make the markup renders to resolve the paths, instead, the
paths are all correctly resolved in the "post process" step.
* Fix#33274
* Since 1.23, all paths starting with "/" are relative to current render
context (for example: the current repo branch)
* Introduce `/:root/path-relative-to-root`, then the path will be
rendered as relative to "ROOT_URL"
Fix#32700, regression of recent markup refactoring
And by the way, clarify many legacy problems:
1. Some "RenderXxx" functions do not really "render", they only call "post processors"
2. Merge "RenderEmoji | RenderCodeBlock", they are all for "simple issue title"
This PR mainly removes some global variables, moves some code and
renames some functions to make code clearer.
This PR also removes a testing-only option ForceHardLineBreak during
refactoring since the behavior is clear now.
This PR removes (almost) all path tricks, and introduces "renderhelper"
package.
Now we can clearly see the rendering behaviors for comment/file/wiki,
more details are in "renderhelper" tests.
Fix#31411 , fix#18592, fix#25632 and maybe more problems. (ps: fix
#32608 by the way)
Remove unmaintainable sanitizer rules. No need to add special "class"
regexp rules anymore, use RenderInternal.SafeAttr instead, more details
(and examples) are in the tests
There were too many patches to the Render system, it's really difficult
to make further improvements.
This PR clears the legacy problems and fix TODOs.
1. Rename `RenderContext.Type` to `RenderContext.MarkupType` to clarify
its usage.
2. Use `ContentMode` to replace `meta["mode"]` and `IsWiki`, to clarify
the rendering behaviors.
3. Use "wiki" mode instead of "mode=gfm + wiki=true"
4. Merge `renderByType` and `renderByFile`
5. Add more comments
----
The problem of "mode=document": in many cases it is not set, so many
non-comment places use comment's hard line break incorrectly
To make the markup package easier to maintain:
1. Split some go files into small files
2. Use a shared util.NopCloser, remove duplicate code
3. Remove unused functions
