Lower minimum macOS to 14 (Sonoma)#86

Conversation
The app required macOS 26 only because a handful of Tahoe APIs were used ungated; nothing in the core depends on 26. Drop the deployment target to 14 (the floor imposed by @observable, which GhosttyKit's macOS 13 binary otherwise allows) and guard each Tahoe-only path: - .glassEffect on the command palette falls back to .regularMaterial. - NSToolbar.allowsDisplayModeCustomization (macOS 15+) is gated. - The Liquid Glass settings (toggle + style picker) are hidden below macOS 26 via the now-exposed WindowAppearance.glassSupported, since the feature doesn't exist there rather than being temporarily unavailable. Verified on a macOS 14 VM: launches and renders natively; build, lint, and tests pass at the 14.0 target.
Reflect the lowered floor: README badge, CLAUDE.md requirements/UI notes, and the Sparkle appcast minimumSystemVersion (so macOS 14 users are offered updates instead of being filtered out).

What
Drops Macterm's minimum macOS from 26 (Tahoe) to 14 (Sonoma) by gating the few Tahoe-only APIs that were used ungated. The deployment target,
LSMinimumSystemVersion, Sparkle appcast floor, and docs all move to 14.Why
The app required macOS 26 only incidentally — a handful of Tahoe APIs were called without availability guards. The core (terminal surface, splits, persistence, hotkeys) has no real 26 dependency. macOS 14 is the practical floor:
@Observable, which the entire state layer uses, needs 14, and below that the build fails with ~87 errors. (GhosttyKit's prebuilt binary itself allows 13.)Changes

macos-26— that's the build host, which needs the 26 SDK to compile the gated glass paths. The deployment target is independent and back-deploys to 14. Downgrading the runner would break the build.WindowAppearanceis gated to 26, so it's a no-op on 14/15 and already works on Tahoe — untested on those VMs only because it doesn't run there.
