refactor(bar): memory, date and update use the platform hooks

The three widgets that differ between the bars only by a platform fact now read it from the hook, in both trees identically: memory opens the task manager through open_system_tool(TaskManager) (was cmd.exe /C taskmgr.exe on Windows, open -a 'Activity Monitor' on macOS: the same commands, now in each platform.rs); date takes its calendar glyph from calendar_icon() (CALENDAR_DOTS on Windows, CALENDAR on macOS); update polls latest_release_api_url() (the komorebi and komorebi-for-mac release APIs) and opens the release page through open_system_tool(Url(..)) (explorer.exe on Windows; on macOS the same explorer.exe it spawns today, broken there, unchanged). After this the memory.rs, date.rs and update.rs of the two bars are byte-identical.

Verified: Windows cargo clippy --workspace --locked --all-targets -D warnings clean; macOS fake-CC cargo check --locked --workspace --all-targets finished, 0 errors; memory.rs, date.rs and update.rs byte-identical across the trees (diff). Note kept as it was: update.rs has a second GitHub API URL (the periodic refresh thread, line 85) that is the komorebi repo in both bars, also on macOS; only the first check goes through the hook. Not verified: clicks and the update check (no screen, no daemon).
