fix(ci): unblock main CI, sort imports + install Playwright Chromium (#7172)

* fix(lint): organize imports in queen_orchestrator.create_queen

Ruff I001 blocks CI on every PR against main. The deferred imports
inside create_queen were not in alphabetical order between the queen
package and the framework package; ruff auto-fix moves
framework.config below the framework.agents.queen.nodes block.

No behavior change.

* fix(ci): install Playwright Chromium before Test Tools job

The new chart_tools smoke tests added in feabf327 require a Chromium
build for ECharts/Mermaid rendering, but the test-tools workflow only
ran `uv sync` and went straight to pytest. Three tests
(test_render_echarts_bar_chart, test_render_echarts_accepts_string_spec,
test_render_mermaid_flowchart) crash on every PR with:

    BrowserType.launch: Executable doesn't exist at
    /home/runner/.cache/ms-playwright/chromium_headless_shell-1208/...

Split the install/run into separate steps and add `playwright install
chromium` before pytest. Use `--with-deps` on Linux to pull system
libraries; Windows runners only need the browser binary.

* fix(tests): adapt test_file_state_cache to new file_ops API

The file_ops rewrite in feabf327 dropped the standalone hashline_edit
tool (the file_system_toolkits/hashline_edit/ directory was removed)
and switched edit_file to a mode-first signature
(mode, path, old_string, new_string, ...).

The test fixture still tried to look up "hashline_edit" via the MCP
tool manager and crashed with KeyError before any test could run, and
the edit_file calls were positional in the old order so they hit
"unknown mode 'e.py'" once the fixture was fixed.

Drop the stale hashline_edit lookup and pass mode="replace" explicitly
to every edit_file call. All 11 tests pass locally.

* fix(tests): skip terminal_tools tests on Windows (POSIX-only)

The new terminal_tools package added in feabf327 imports the Unix-only
`resource` module in tools/src/terminal_tools/common/limits.py to set
RLIMIT_CPU / RLIMIT_AS / RLIMIT_FSIZE on subprocesses. Five of the
six terminal_tools test files therefore crash on windows-latest with
`ModuleNotFoundError: No module named 'resource'` once their fixtures
trigger the import chain.

test_terminal_tools_pty.py already has the right module-level skip
(PTY is POSIX-only). Apply the same `pytestmark = skipif(win32)` to
the other five so the whole suite skips cleanly on Windows. The
terminal-tools package is bash-only by design (zsh refused at the
shell-resolver level), so a Windows port is out of scope.
