feat: add calculator provider and frecency tracking

Calculator: - Type "= expression" or "calc expression" for instant math evaluation - Supports standard math functions (sqrt, sin, cos, etc.) and constants (pi, e) - Copies result to clipboard on Enter via wl-copy Frecency: - Firefox-style algorithm: score = launch_count * recency_weight - Boosts frequently and recently launched items in search results - Persists to ~/.local/share/owlry/frecency.json - Configurable via providers.frecency and providers.frecency_weight New config options: - providers.calculator = true - providers.frecency = true - providers.frecency_weight = 0.3 UI updates: - Added :calc prefix support - Calculator badge with yellow styling - Updated hints to show "= calc" syntax 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

+# Owlry - Claude Code Instructions
+
+## Release Workflow
+
+Always use `just` for releases and AUR deployment:
+
+```bash
+# Bump version (updates Cargo.toml + Cargo.lock, commits)
+just bump 0.x.y
+
+# Push and create tag
+git push && just tag
+
+# Update AUR package
+just aur-update
+
+# Review changes, then publish
+just aur-publish
+```
+
+Do NOT manually edit Cargo.toml for version bumps - use `just bump`.
+
+## Available just recipes
+
+- `just build` / `just release` - Build debug/release
+- `just check` - Run cargo check + clippy
+- `just test` - Run tests
+- `just bump <version>` - Bump version
+- `just tag` - Create and push git tag
+- `just aur-update` - Update PKGBUILD checksums
+- `just aur-publish` - Commit and push to AUR
+- `just aur-test` - Test PKGBUILD locally

vikingowl	1608582cbd	fix: detect dmenu mode correctly using fstat Previously, poll() on /dev/null returned "readable" (EOF), causing dmenu mode to trigger when launched from keybinds. Now uses fstat() to check if stdin is a pipe or regular file before checking for data. Character devices (TTY, /dev/null) no longer trigger dmenu mode. Fixes items not showing when launched from window manager keybinds. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2025-12-28 16:07:59 +01:00
