chore(deps): bump github.com/chromedp/chromedp from 0.16.0 to 0.20.1

[dependabot]

Bumps github.com/chromedp/chromedp from 0.16.0 to 0.20.1.

Release notes

Sourced from github.com/chromedp/chromedp's releases.

v0.20.1

Documentation only. The README, the package documentation and the docs have the current versions (chromedp v0.20.0, cdproto v0.157.8, remote v0.2.0), the CI matrix and the release history. The README describes termcast and the 43 programs of chromedp/examples.

v0.20.0

chromedp supports Go 1.25 and later. Before this release, the module needed Go 1.27 (see #1536).

• The JSON types come from github.com/chromedp/cdproto/cdp/jsonv2. With Go 1.27 or GOEXPERIMENT=jsonv2 they are aliases of the types of the standard encoding/json/v2 and jsontext, so the public API is the same. With Go 1.25 and 1.26 they come from github.com/go-json-experiment/json.
• The modules chromedp, remote and test use go 1.25 and cdproto v0.157.8.
• The CI runs Go 1.25, 1.26 and stable on Linux, stable on Windows and macOS, and the experiment and the compatibility tag.

v0.19.1

Documentation only. The README and the package documentation describe termcast, which draws the screen of a page in a terminal, and the 43 programs of chromedp/examples.

v0.19.0

This release adds new actions and options, fixes bugs, and works on Linux, Windows and macOS in CI. See docs/MIGRATION.md for every change.

New

• Tap and TapXY send a touch tap.
• DragAndDrop and DragAndDropXY drag and drop with the mouse and with HTML5 drag and drop.
• Console reads the console, the uncaught exceptions and the browser log of a page as one iterator.
• ExposeFunc calls a Go function from the page, like exposeFunction in Puppeteer.
• PrintToPDF takes options for the paper, the margins, the scale, the page ranges, the header and the footer, the outline and a stream.
• WithNewWindow chooses a window or a tab for a new target. NoInheritEnv starts the browser with only the given variables. WithDetachOnCancel leaves the tab open when the context ends.
• EvalAwaitPromise waits for a promise that an expression returns.

Fixed

• Call on a Target or a Browser returns an error when the connection to the browser is lost, and does not hang.
• The exec allocator keeps the order of the flags.
• WaitNotPresent works with a JSPath that gives null or an empty list.
• Evaluate returns ErrJSNull for null when the type cannot be nil, and Text works on a text node.
• The pipe transport, the allocator and the tests work on Windows and macOS, and the default browser lookup on Windows falls back to Microsoft Edge.

Notes

• Use errors.Is(err, context.Canceled) and not == for the error of a call after the connection was lost.
• The tests run on Linux, Windows and macOS in CI, and every night against the stable, beta and dev channels of headless-shell.
• The module github.com/chromedp/chromedp/remote is unchanged and stays at remote/v0.1.0.

Maintainer resolution

The dependency bump changed chromedp's action API and broke compilation of the rendered Ask fallback. Migrated navigation to Do, results to typed Run/PollFunction actions, and evaluation fixtures to the nullable/value-aware API without changing provider ordering, answer parsing, or request deadlines.

Expanded the offline browser fixtures to cover delayed/short Search Assist answers, nullable empty results, modern/legacy result cards, duplicate and unsafe-link filtering, polling timeouts, and child-context cancellation. CI now locates the installed Chrome/Chromium browser and executes these fixtures rather than silently skipping them. Fixtures use synthetic pages and do not contact DuckDuckGo or IRC.

Validation: full repository race tests with real Chrome passed on Go 1.26.9 and Go 1.27.2. Go vet, Staticcheck, module verification, govulncheck, native build, and CGO-disabled Linux/amd64 build passed. Verify, Analyze Go, and CodeQL passed before merge.

Includes the already-reviewed build baseline from #169 and CodeQL update from #170; those PRs were merged first. Rebuild/restart is required to apply runtime changes. Production was not changed by this PR-resolution task.
