Add automation-friendly browser launch defaults

[konard]

Summary

• apply the same automation-friendly Chromium defaults in JavaScript, Python, and Rust, including --password-store=basic, first-run suppression, and the existing crash/infobar protections
• use the full defaults when launching an installed Chrome, Edge, Brave, or Chromium while keeping CDP on loopback with a dedicated, protected profile and --headless=new when requested
• add extraArgs / extra_args / Rust extra-argument builders and per-default opt-outs without breaking the existing args APIs
• document every default and its reason, the Chrome 136+ dedicated-profile requirement, and why attach-only connect APIs cannot retrofit flags onto an existing process
• add minor-release metadata for all three packages

Root cause and reproduction

The shared launch argument lists did not include --password-store=basic, so a fresh Chrome-family profile could invoke the operating-system credential backend. The installed-browser launch helpers also hard-coded only the two first-run flags, and none of the language APIs resolved additive arguments together with per-default opt-outs.

Before this change, inspecting the default arguments produced by launchBrowser / launch_browser or buildRealBrowserArgs / build_real_browser_args showed that --password-store=basic was absent. The new unit regressions assert that it is present by default, custom arguments retain append order, individual defaults (including the password-store flag itself) can be omitted, and managed CDP/profile arguments remain protected.

connectBrowser / connect_browser attaches to an already-running process and therefore cannot alter its command line. The documentation now makes that boundary explicit and points callers to the real-browser launch helper or equivalent external flags.

Verification

• JavaScript: 502 unit tests; ESLint; Prettier; duplication check; changeset status; API docs
• Python: 268 tests with coverage; Ruff check/format; mypy; wheel and sdist build; Twine validation
• Rust: all-feature tests and doctests with warnings denied; rustfmt; Clippy; API docs; optimized release build; package listing; file-size check
• Final working tree is clean and current origin/main is included

Fixes #70

Working session summary

Implemented and finalized PR #74.

• Added `--password-store=[REDACTED] and consistent automation defaults across JavaScript, Python, and Rust.
• Added extra arguments and per-default opt-outs.
• Preserved protected loopback CDP and dedicated profiles; headless real-browser launches use --headless=new.
• Documented defaults, rationale, and attach-only connectBrowser limitations.
• Added regression tests and release metadata.
• Local suites passed: 502 JavaScript tests, 268 Python tests, full Rust tests/lint/package checks.
• Fresh CI passed on Linux, macOS, and Windows for commit 444fd36.
• PR is ready for review, mergeable, and clean.
