Match Obsidian's dotted window class in the focus binding

[ya-luotao]

Problem

SUPER + SHIFT + O looks dead once Obsidian is running (#8902). The binding is { launch = "obsidian", focus = "^obsidian$" }, which omarchy-launch-or-focus wraps as \b^obsidian$\b against each window's class and title. That matches a window whose class is exactly obsidian, but current Obsidian builds report the class md.obsidian.Obsidian, so the focus branch never matches, the script relaunches Obsidian every time, and Obsidian's single-instance lock swallows the new process without raising the existing window.

Fix

Change the pattern to ^(md\.obsidian\.)?obsidian$ (Lua literal "^(md\\.obsidian\\.)?obsidian$"). It matches both the bare obsidian class and md.obsidian.Obsidian, case-insensitively, while keeping the anchors.

The anchors are deliberate: #1838 anchored this binding because a window titled "Obsidian is great!" stole the key, and ec59388 re-anchored it after the script went back to \b matching. Dropping them to a bare obsidian would fix #8902 but reintroduce that false match.

Fed through the exact jq expression from bin/omarchy-launch-or-focus:

client	^obsidian$ (old)	^(md\.obsidian\.)?obsidian$ (new)
class obsidian	✅	✅
class md.obsidian.Obsidian	❌ (the bug)	✅
firefox, title "Obsidian - Mozilla Firefox"	❌	❌
class obsidianite	❌	❌
class org.obsidian.foo	❌	❌

Verification

• jq matrix above against the expression in bin/omarchy-launch-or-focus:13.
• applications.lua is required from $OMARCHY_PATH/default/hypr/bindings/ via default.hypr.omarchy, not copied into ~/.config, so the change reaches existing installs on update; no migration needed.
• test/shell.d/launch-1password-test.sh and test/shell.d/hyprland-default-config-test.sh pass.
• Not exercised against a running Hyprland (developed on macOS). A quick hyprctl clients -j | jq -r '.[].class' | grep -i obsidian on an Omarchy box before/after would confirm the class value.
