feat(browserless): add report() hardware & GPU diagnostics

[Kikobeats]

Add a report() context method that returns a normalized snapshot of the environment a page renders in: browser build (name/version/headless/channel/ build + full and app-only launch args), virtualization/container detection, OS/CPU/memory, and the GPU stack parsed from the ANGLE renderer string (vendor/device/type, graphics API, mesa/llvm/simdWidth) plus per-version WebGL capabilities/extensions and WebGPU support.

Optionally runs a small deterministic WebGL benchmark (report({ benchmark: true })) for comparing environments and catching render regressions after Chrome/Mesa/LLVM/flag/infra changes.

Includes TypeScript types (HardwareInfo) and tests.

Note

Low Risk
Additive API on the existing withPage lifecycle; no changes to launch or navigation defaults, though CDP command-line reads and optional benchmark add modest runtime when used.

Overview
Adds report() on each browserless context (wired through withPage like pdf/screenshot) so callers get a single HardwareInfo snapshot of where pages actually render.

The implementation collects browser metadata (version, headless, channel/build, sanitized launch args vs driver.defaultArgs via CDP), host OS/CPU/memory and VM/container hints, and GPU data from in-page WebGL/WebGPU probes with ANGLE renderer parsing (vendor/device, hardware vs software—including SwiftShader detection—plus optional Mesa via dpkg-query on Linux). report({ benchmark: true }) optionally runs a short deterministic WebGL timing loop and attaches performance.webgl.

index.d.ts documents HardwareInfo and related types. Tests cover detectBuild path heuristics, integration report() shape (CI pins Mesa/llvmpipe), and the benchmark path.
