## Message

```
gpui: Expose accessibility identifiers to platform clients (#61926)

# Objective

- Fixes #61925.
- GPUI already carries AccessKit author IDs through its platform
adapters, but applications cannot set one on an ordinary element.

## Solution

- Add `accessibility_id(...)` beside the other semantic builders.
- Store the value separately from GPUI's element ID and write it to
`Node::set_author_id`.
- Document that applications should keep the value stable and unique
within the accessibility tree.
- Document the platform mapping accurately: UIA `AutomationId` on
Windows, `AXIdentifier` on macOS, and AT-SPI `AccessibleId` on Linux
stacks whose deployed adapter exposes it.

## Testing

Exact candidate `d099c529`:

- `cargo fmt --all -- --check`
- `git diff --check`
- `cargo test -p gpui test_accessibility_id_builder_writes_author_id
--offline`: 1 passed, 218 filtered out

The test exercises the public builder and verifies that the author ID
reaches the AccessKit node. Validation is unit-level; this branch has
not run live platform UIA, AX, or AT-SPI end-to-end tests.
