Fix remaining SonarCloud and Codacy findings

Refactor 21 high-complexity functions into smaller helpers (keyPressEvent,
_show_diff_for_change, set_plugin_menu, add_dock_widget, redirect,
startup_setting, check_all_format, toggle_comment, _assign_lanes,
_parse_unified_diff, _reapply_highlights_for_theme, run_program,
load_external_plugins, PythonHighlighter.__init__, etc.), rename camelCase
locals to snake_case, replace `list()`/`dict()` with literals, extract
duplicated string literals into module-level constants, remove unused
imports and parameters, drop dead-code comments, fix always-true
conditions, and rename `copyright` to `project_copyright`.

Tighten security surface: validate http(s) scheme before urlopen in
github_api, resolve and confine replace paths to project root to block
traversal, drop "http://" literal from clone URL parser, narrow broad
`except Exception` clauses to specific IO errors, reraise SystemExit in
CI entry points, add nosec justifications on legitimate subprocess/urllib
calls, and configure `[tool.bandit] exclude_dirs` in pyproject and
dev.toml to silence assert-in-tests B101 noise.
