✨ feat: fzf README preview with glow support

- Show README.md in the right 40% of the fzf picker on hover
- Render with glow (CLICOLOR_FORCE=1 for colors in non-TTY pipe) when available, fall back to cat
- Preview command uses sh -c for fish/zsh/bash compatibility
- Bump version to 0.10.0

+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
+
+## [0.10.0] - 2026-03-05
+
+### Added
+- fzf preview panel: hovering over a project shows its `README.md` in the right 40% of the screen
+- Uses `glow` for rendered markdown when available, falls back to `cat`
+- `CLICOLOR_FORCE=1` ensures glow outputs full ANSI colors even in fzf's non-TTY preview pipe
+- Preview command runs via `sh -c '...' -- {}` for compatibility with fish, zsh, and bash
+
+## [0.9.2] - 2026-03-04
+
+### Changed
+- Cache now uses stale-while-revalidate: cached projects are returned immediately and a background process (`--background-refresh`) rebuilds the cache when it is stale, eliminating blocking scans on every invocation
+- `cache_ttl_hours` is now enforced: when the cache age exceeds the configured TTL, a background refresh is triggered automatically
+
+## [0.9.1] - 2026-03-01
+
+### Fixed
+- Shortcut and desktop integration wizards are now offered regardless of whether the user chose the interactive wizard or the default config on first run; previously they were only offered in the wizard path
+
+## [0.9.0] - 2026-03-01
+
+### Added
+- First-run setup choice prompt: when no configuration file exists, tmuxido now asks whether to run the interactive wizard or apply sensible defaults immediately
+- `SetupChoice` enum and `parse_setup_choice_input` in `ui` module (pure, fully tested)
+- `Config::write_default_config` helper for writing defaults without any prompts
+- `Config::run_wizard` extracted from `ensure_config_exists` for clarity and testability
+- `render_setup_choice_prompt` and `render_default_config_saved` render functions
+
+## [0.8.3] - 2026-03-01
+
+### Fixed
+- `Cargo.lock` now committed alongside version bumps
+
+## [0.8.2] - 2026-03-01
+
+### Fixed
+- `install.sh`: grep pattern for `tag_name` now handles the space GitHub includes after the colon in JSON (`"tag_name": "x"` instead of `"tag_name":"x"`)
+
+## [0.8.1] - 2026-03-01
+
+### Fixed
+- `install.sh`: removed `-f` flag from GitHub API `curl` call so HTTP error responses (rate limits, 404s) are printed instead of silently discarded; shows up to 400 bytes of the raw API response when the release tag cannot be parsed
+
+## [0.8.0] - 2026-03-01
+
+### Added
+- Keyboard shortcut setup wizard on first run and via `tmuxido --setup-shortcut`
+- Auto-detects desktop environment from `XDG_CURRENT_DESKTOP` / `HYPRLAND_INSTANCE_SIGNATURE`
+- Hyprland: appends `bindd` entry to `~/.config/hypr/bindings.conf`; prefers `omarchy-launch-tui` when available, falls back to `xdg-terminal-exec`
+- GNOME: registers a custom keybinding via `gsettings`
+- KDE: appends a `[tmuxido]` section to `~/.config/kglobalshortcutsrc`
+- Conflict detection per DE (Hyprland via `hyprctl binds -j`, KDE via config file, GNOME via gsettings); suggests next free combo from a fallback list
+- `--setup-desktop-shortcut` flag to (re-)install the `.desktop` entry and icon at any time
+- `shortcut` module (`src/shortcut.rs`) with full unit and integration test coverage
+- Icon and `.desktop` file installed by `install.sh` and offered in the first-run wizard
+
+## [0.7.1] - 2026-03-01
+
+### Fixed
+- Interactive setup wizard now asks for a tmux layout when a window has 2 or more panes
+- Layout selection shown in post-wizard summary
+
+### Changed
+- README: Added ASCII art previews for each available tmux layout
+
+## [0.7.0] - 2026-03-01
+
+### Changed
+- `install.sh` now downloads from GitHub Releases
+- Self-update now queries the GitHub Releases API for new versions
+- Releases are published to both Gitea and GitHub
+
+## [0.6.0] - 2026-03-01
+
+### Added
+- Periodic update check: on startup, if `update_check_interval_hours` have elapsed since
+  the last check, tmuxido fetches the latest release tag from the Gitea API and prints a
+  notice when a newer version is available (silent on network failure or no update found)
+- New `update_check` module (`src/update_check.rs`) with injected fetcher for testability
+- `update_check_interval_hours` config field (default 24, set to 0 to disable)
+- Cache file `~/.cache/tmuxido/update_check.json` tracks last-checked timestamp and
+  latest known version across runs
+
+## [0.5.2] - 2026-03-01
+
+### Added
+- Test for `detect_arch` asserting asset name follows `tmuxido-{arch}-linux` format
+
+## [0.5.1] - 2026-03-01
+
+### Fixed
+- Tmux window creation now targets windows by name instead of numeric index, eliminating
+  "index in use" and "can't find window" errors when `base-index` is not 0
+- Self-update asset name corrected from `x86_64-linux` to `tmuxido-x86_64-linux` to match
+  what CI actually uploads, fixing 404 on `--update`
+- CI release pipeline now deletes any existing release for the tag before recreating,
+  preventing 409 Conflict errors on retagged releases
+
+## [0.5.0] - 2026-03-01
+
+### Added
+- Interactive configuration wizard on first run with styled prompts
+- `lipgloss` dependency for beautiful terminal UI with Tokyo Night theme colors
+- Emoji-enhanced prompts and feedback during setup
+- Configure project paths interactively with comma-separated input
+- Configure `max_depth` for project discovery scanning
+- Configure cache settings (`cache_enabled`, `cache_ttl_hours`)
+- Configure default session windows interactively
+- Configure panes within each window with custom names
+- Configure startup commands for each pane (e.g., `nvim .`, `npm run dev`)
+- New `ui` module with styled render functions for all prompts
+- Comprehensive summary showing all configured settings after setup
+
+## [0.4.2] - 2026-03-01
+
+### Fixed
+- Version mismatch: bumped Cargo.toml version to match release tag, fixing `--update` false positive
+
+## [0.4.1] - 2026-03-01
+
+### Added
+- Self-update feature (`tmuxido --update`) to update binary from latest GitHub release
+
+## [0.4.0] - 2026-03-01
+
+### Added
+- Self-update feature (`tmuxido --update`) to update binary from latest GitHub release
+- New `self_update` module with version comparison and atomic binary replacement
+- `--update` CLI flag for in-place binary updates
+- Backup and rollback mechanism if update fails
+
+## [0.3.0] - 2026-03-01
+
+### Added
+- Dependency check for `fzf` and `tmux` at startup, before any operation
+- Automatic Linux package manager detection (apt, pacman, dnf, yum, zypper, emerge, xbps, apk)
+- Interactive installation prompt when required tools are missing
+- `deps` module with injectable `BinaryChecker` trait for unit testing without hitting the real system
+- Integration tests in `tests/deps.rs` (11 tests using real `SystemBinaryChecker`)
+- Docker test suite in `tests/docker/` with 15 scenarios simulating a fresh Ubuntu 24.04 user
+
+### Fixed
+- Release pipeline `publish` step now reads `DRONE_TAG` via awk `ENVIRON` to prevent Drone's
+  `${VAR}` substitution from wiping local shell variables before the shell runs
+
+## [0.2.4] - 2026-03-01
+
+### Fixed
+- Coverage percentage calculation in CI (correct field from tarpaulin JSON output)
+- Release pipeline trigger now matches `v*` tag format instead of `[0-9]*`
+
+## [0.2.2] - 2026-02-28
+
+### Added
+- Coverage badge generated by `cargo-tarpaulin` in CI, hosted in Gitea Generic Package Registry
+- CI status, coverage, version, and Rust edition badges in README
+
+## [0.2.1] - 2026-02-28
+
+### Added
+- Drone CI pipeline (`ci`) running `cargo fmt --check`, `cargo clippy`, and `cargo test` on every push and pull request
+
+## [0.2.0] - 2026-02-28
+
+### Added
+- Unit tests for `cache`, `session`, and `config` modules
+- Integration tests for scan, session config, and cache lifecycle
+
+### Changed
+- Refactored business logic into `lib.rs` for better testability; `main.rs` is now a thin entrypoint
+
+## [0.1.1] - 2026-02-28
+
+### Fixed
+- Removed personal path references from default configuration and examples
+
+## [0.1.0] - 2026-02-28
+
+### Added
+- Initial release of tmuxido
