feat(core): add macos desktop switch actions

[LouisDISPA]

Context

Adds macOS desktop switching actions and separates. At first I tried to use ctrl + arrow shortcuts but it did not work. Then I used an AI agent (codex) to take the implementation in Mouser and translate it for this repo. I also cleaned a bit the code to share the symbol resolver and cache with the dock implementation.

Summary

• Add PreviousDesktop and NextDesktop actions
• Route macOS Space switching through CGS symbolic hotkeys

Testing

Chip: Apple M5
System Version: macOS 26.5
Mouse: MX Vertical
Connection: Bluetooth

ℹ️ Minor suggestion only — one test-coverage gap worth fixing before merge.

Reviewed changes — adds PreviousDesktop and NextDesktop macOS Space-switching actions, extracted a shared app_services symbol resolver from the dock module, and added translations for both new actions.

• Add PreviousDesktop/NextDesktop variants — new Action enum members, their label()/category()/catalog() entries, and routing through Action::execute() to the new symbolic_hotkey submodule
• Extract shared app_services symbol resolver — factored dlopen/dlsym out of dock into a sibling module so both dock and symbolic_hotkey can resolve private ApplicationServices SPI symbols
• Implement CGS symbolic hotkey switching — new symbolic_hotkey module reads the configured symbolic hotkey record for Space Left/Right (IDs 79/81), temporarily enables the hotkey if disabled, posts the key event, and restores state
• Add locale entries — translations for ja, ru, zh-CN, zh-HK

Reviewed changes — force-push (e7c05e6 → 81a866b) that adds the category_navigation_variants test assertions for PreviousDesktop/NextDesktop, closing the prior review's test-coverage gap.

• Add category_navigation_variants test coverage — two new assertions verify that Action::PreviousDesktop and Action::NextDesktop both return Category::Navigation
