jaredandClaude Opus 4.8 30d0331174 fix(ui): isMacOS always returned false on Macs + plugin-logic tests (+49)
Coverage work found a 3rd real bug: isMacOS() compared os.name against the
legacy 'Mac OS' string, but ua-parser-js v2 reports 'macOS' — so it was dead,
and Mac users saw "Ctrl + k" instead of "⌘ + k" in the editor toolbar, search,
and settings shortcut hints. Now accepts both 'macOS' and 'Mac OS'.

Suites (via subagent, verified): via-servers (10 — power/popularity server
selection), bad-words (9), syntaxHighlight tokenize (14), plugins/utils
getEmoticonSearchStr (5), imageCompression formatFileSize/isCompressible (5),
user-agent (6, now asserting the fixed behavior).

Full suite now 501 tests, all passing.
