fix(cli): accept browser --window placed after the subcommand (#1850)

[LeoLin990405]

What

opencli browser <session> <subcommand> ... --window <mode> fails with error: unknown option '--window' (#1850).

--window is registered on the browser parent command, so commander only accepts it before the leaf subcommand:

• ✅ opencli browser work --window background open https://x.com
• ❌ opencli browser work open https://x.com --window background ← the obvious placement

Fix

rewriteBrowserArgv (the existing browser <session> <subcommand> argv preprocessor) now hoists a trailing --window <mode> / --window=<mode> to the parent option slot, so both placements parse identically. argv without --window is unchanged; only the first occurrence is hoisted; the scan stops at --.

Tests / verification

• 4 new rewriteBrowserArgv cases: trailing form, = form, already-in-slot no-op, and with a leading --profile. vitest run src/cli-argv-preprocess.test.ts → 32 passed.
• Live: opencli browser <session> open https://example.com --window background now opens the page (previously errored with unknown option '--window').

Fixes #1850

Thanks for the focused fix. I compared this with #1899 because both PRs address #1850.

I opened a replacement PR that uses your lower-blast approach as the core design: keep --window as a browser namespace option and hoist the natural trailing form in rewriteBrowserArgv, instead of changing the browser command tree.

Replacement PR: #1963

I also credited you in the replacement commit as a co-author:

Main differences in #1963:

• adds nested command coverage like browser work get url --window background and browser work tab close ... --window background
• avoids rewriting anything after literal --
• avoids hoisting a bare --window without a value, so Commander cannot accidentally consume the subcommand token as the option value
• adds a browser help example for the trailing placement

Makes sense — #1963 is the better version (nested-command coverage + the -- / bare---window edge cases). Closing this in favor of it. Thanks for folding in the approach and the co-author credit! 🙏
