Remove the completed DXIL migration recipe and its command-line option. Keep archive pin/checksum generation, reviewed dependency registrations, SwiftShader synchronization, and ordered patch refreshes in one workflow. Write a Markdown review report alongside the JSON report and patch. Report existing manifest drift and preserve patch-inspection errors as blockers without applying partial edits. Match fetched dependencies by repository and commit so one revision cannot stand in for another checkout. Document the distinction between reviewed manifests and fetched build inventories. Preserve independent DXC release/package metadata. Validation: 49 tests and 24 subtests pass; Ruff and whitespace checks pass. Replaying microsoft#33390 generates both changed files exactly. Both microsoft#32686 and microsoft#33390 replays reproduce all dependency identities/pins and final patched source, with idempotent apply/check. No dependency roll is applied here.

Dawn updates currently require coordinating the archive pin, dependency hashes, SwiftShader revision, and local patches. Add a single command to prepare, apply, and validate these changes together: ```sh python plugin-ep-webgpu/tools/dawn/update_dawn.py ``` The command defaults to the newest dated Dawn tag. Use `--revision <tag-or-full-commit>` to select a specific version. It records the concrete revision and checksum, updates the reviewed dependency manifest and Linux test SwiftShader pin, and refreshes active patches in CMake order. Refreshed patches must reproduce the expected source with zero fuzz or offsets. The command verifies written contents and automatically validates the manifest against the selected checkout. Unresolved patches or dependency changes needing classification stop the update; writing or final-validation failures trigger restoration of every attempted file, continuing after individual restoration errors and reporting them alongside the original failure. Reports and a diff are saved under `build/dawn-upgrade/`, and repeating the same update makes no further edits. Dependency classifications and the independently packaged DXC release are preserved. DXIL handling is outside the scope. A manifest-only updater remains available for focused maintenance. This PR contains eight tooling, test, and documentation files. Build-inventory generation and packaging-pipeline integration are in #33448. Dawn version updates generated during local validation are separate from this PR. Validation: - 49 tests and 29 subtests passed with ordinary and aliased Windows temporary paths, including real GNU patch application, latest-tag resolution, metadata preservation, repeat runs, persistent write failures, partial writes, and multiple rollback failures. Recovery was also verified with a real read-only manifest. - Ruff lint/format and Git whitespace checks passed. - An isolated update from `v20261013.193955` to `v20261016.190333` changed nine files and passed automatic manifest and strict patch validation. A second invocation changed zero files. - Earlier pinned comparisons reproduced #33390's two changed files exactly and #32686's dependency identities and revisions. The command automates source updates and metadata/patch validation. Build, package, and GPU tests remain necessary to establish runtime compatibility for each Dawn update.
