refactor(sonar): extract helpers to reduce main() complexity (python:S3776)

[setchy]

Summary

SonarCloud issue — python:S3776

python:S3776 flags main() in scripts/test-live.py for a cognitive complexity of 28 (threshold: 15). Sonar's Python analyzer counts the bodies of nested functions toward the enclosing function, so the helper closures defined inside main() (inspect, visible, tray_item, beside_panel, activate, …) were all inflating it.

This PR extracts those helpers to module level, dropping main() to a cognitive complexity of 9 with every extracted helper well under the threshold.

Changes

• start_gitify(temporary) — launch Gitify against isolated XDG dirs, return (process, log)
• inspect(process, temporary, probe_name, mutation="") — write and load the KWin probe script
• visible(...) — first visible Gitify window
• tray_item(process) / activate_tray(service, path) — StatusNotifier look-up and activation
• beside_panel(...) / has_8px_gap(frame, panel) — 8px panel-gap placement check
• inspector_endpoint(temporary) / resize_expression(frame) / resize_window(endpoint, expression) — CDP resize against the inspector

No behavior is changed: same DBus calls, same script, same output, same cleanup in finally.

Rebased onto latest main to pick up chore(sonar): document loopback-only inspector connection (python:S5332) (#7). The moved ws:// regex in inspector_endpoint() keeps the # NOSONAR(S5332) suppression, so the previous "Security Rating on New Code" quality-gate failure is resolved (the insecure-transport rule is expected and documented for the loopback-only DevTools endpoint).

Validation

• node --check gitify/contents/code/main.js — passes
• bash -n scripts/install.sh scripts/bundle.sh — passes
• python3 -m py_compile scripts/test-live.py — passes
• npm test — 13/13 pass
• Cognitive complexity re-computed with the cognitive-complexity package: main 9, next highest helper 8 (all ≤ 15)
