feat(mc): add midnight commander with declarative config

Public baseline module: installs `mc` plus `ouch` (backs the F2 pack/unpack entries, archive format inferred from the extension), and ships `ini`, `menu`, and a generated `panels.ini` into `$XDG_CONFIG_HOME/mc`. `local.mc.otherDir` exposes the other-panel start dir as an option defaulting to `config.home.homeDirectory`, so the one personal value isn't baked in. The F2 user menu is trimmed to the entries that match this config (imv/zathura/mpv openers, ouch pack/unpack, man view); the stock rcp/uudecode/news/latex cruft is dropped. `auto_save_setup=false` keeps mc from rewriting the read-only store symlinks on exit.

+# Midnight Commander: TUI file manager. Its config (ini, panels, F2 user menu)
+# is opinionated but generic, so it lives in the public baseline alongside the
+# other desktop tooling. The only personal value is the right-panel start dir,
+# exposed as an option defaulting to the consumer's own home.
+#
+# ouch backs the F2 pack/unpack entries (one tool, archive format inferred from
+# the extension), so it ships with mc to keep the menu self-contained.
+#
+# mc honours XDG natively: config in $XDG_CONFIG_HOME/mc (the files below),
+# mutable runtime state (history, cursor positions) in $XDG_DATA_HOME/mc — no
+# env vars needed. `ini` sets auto_save_setup=false so mc never rewrites these
+# read-only store symlinks on exit.
