fix: extend auto waituntil timeout

[Kikobeats]

Note

Low Risk
Packaging and timeout tuning only; no auth or data-path changes, though goto auto-wait behavior may differ on slow pages.

Overview
Declares puppeteer v25 as a peer dependency on @browserless/goto, matching its runtime import from puppeteer without bundling it as a direct dependency.

Adds p-reflect to @browserless/pdf because the PDF entrypoint requires it directly.

For waitUntil: 'auto', the post-navigation network-idle wait now uses gotoTimeout instead of actionTimeout * 2, so auto-wait shares the same timeout budget as navigation and related waits.
