v1.57.8.0 feat: browse js/eval --out render-to-file (canonical Chromium for offline rendering) (#1929)

Browse Source 
* feat(browse): js/eval --out render-to-file with write-capability gate

Add --out <file> / --raw to js and eval so an evaluate result is written
straight to disk (base64 data URLs auto-decoded to bytes, charset-validated
before decode, parent dirs created) instead of serialized back through the
CLI. --out is modeled as a per-invocation WRITE: it requires write scope, is
never dispatchable over the pair-agent tunnel (canDispatchOverTunnel now
consults args), and counts as a mutation for watch-mode and tab-ownership.
Shared parseOutArgs/hasOutArg/resultToString helpers keep the handler and the
gate in sync. Tests cover the parser, render-to-file paths, and tunnel guards.

* docs(browse): offline render mode + canonical-Chromium guidance

Document the blessed offline-render path (headless, no proxy/Xvfb): visual
output via screenshot --selector, bytes a function returns via js --out.
Add the puppeteer->browse cheatsheet row, a "don't bundle your own Chromium"
note (browse skill + CONTRIBUTING), and the --out/--raw command descriptions.
Regenerate browse/SKILL.md, SKILL.md, and gstack/llms.txt from the templates.

* chore: bump version and changelog (v1.59.1.0)

* docs: document js/eval --out render-to-file in BROWSER.md reference (v1.59.1.0)

The js and eval reference rows in BROWSER.md drifted: every other reference
surface (SKILL.md, gstack/llms.txt, browse/SKILL.md) already shows the new
[--out <file>] [--raw] flags from v1.59.1.0, but the complete browser
reference still showed the pre-feature signatures. Add the flags plus the
WRITE-capability / no-tunnel note so the reference matches what shipped.

* chore: re-version 1.59.1.0 -> 1.57.8.0 (natural PATCH from 1.57.7.0)
