🔖 chore: bump version to 0.7.1 and update CHANGELOG

Add `render_layout_prompt` and `parse_layout_input` to ui.rs so that
the first-run wizard asks the user to choose a tmux layout (1–5 or by
name) for each window that has 2 or more panes. Previously, layout was
always silently set to None.

Also update `render_config_created` to display the chosen layout in the
post-setup summary.

Closes: layout never being set during interactive setup

+## [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
