v1.4.0 — Layered XDG config, CLI redesign

What's New

Layered XDG-style config discovery (contributed by @kay-ws, #13 #14 #15)

Config files are now merged in layers, matching helix/mpv/neovim conventions:

Layer	Path	Notes
Built-in	Config::default()	Always loaded
System	/etc/bcon/config.toml	Installed by package manager
User	~/.config/bcon/config.toml	Per-user overrides (wins)

Tables merge recursively; scalars and arrays replace wholesale. Users only need to specify the keys they want to override.

BCON_CONFIG env var — bypass all layers and load a single file (useful for debugging: BCON_CONFIG=/dev/null bcon gives pure defaults).

--init-config CLI redesign (contributed by @kay-ws)

Explicit target token eliminates the root-shadow trap:

sudo bcon --init-config=system          # → /etc/bcon/config.toml
bcon --init-config=user,vim,jp          # → ~/.config/bcon/config.toml
bcon --init-config=/tmp/test.toml,vim   # → custom path

Legacy --init-config=vim,jp continues to work unchanged.

Distributors API

Config::default_template() — renders the built-in defaults as TOML for packaging. Distributors can ship /etc/bcon/config.toml without running the bcon binary at package time.
