yenru0 5fd4113081 image_viewer: Add anchored zoom and pan to the PDF viewer
The PDF viewport lacked the interaction set the image view already had:
ctrl/cmd+wheel and pinch zoomed nothing (plain wheel just scrolled),
middle-drag did not pan, and the zoom actions only applied image-mode
pan math, which does nothing for the scroll-based PDF layout.

- Ctrl/cmd+wheel zooms around the cursor: the native scroll handler on
  the same element runs first in the bubble phase, so the applied wheel
  delta is undone before anchoring the zoom.
- Pinch zooms around the touch point; zoom actions anchor the viewport
  center.
- Middle-drag pans, keeping left-drag for text selection and pen input.
- extract_document_details now falls back to a single mock US-Letter
  page when no native libpdfium is present, mirroring the mock
  rasterizer, so PDFs open on machines without the engine instead of
  failing with an image-format error.
- The annotation mouse test gates on native pdfium like the channel
  order test, since mock pages carry no text.

Anchor math lives in pdf_anchored_scroll_y with unit tests, and a
gpui integration test drives real wheel/drag events to assert the
document point under the cursor stays put while zooming.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.
