Long-only (no free short letter left), lists each volume's name and
host directory, tab-aligned the same way -l/--list-images already
aligns name:tag output -- list_volumes_command() reuses that scheme.

Creates the host directory if missing (warning if it already exists,
another if it's non-empty) and records name -> directory in the config
file's new "volumes" section. Fails if the name or directory is already
used by an existing volume.
This is a distinct concept from OciImageConfig::volumes (an image's own
declared mount points, still unconsumed) -- a user-defined volume, meant
to be referenced by name once -r/--run starts actually mounting volumes.
config_file.{h,cpp} gains write_config_file(), symmetric to the existing
load_config_file(), built on libyaml's document-building/emitter API.
Rewrites the whole file each time; global.log-level round-trips
untouched alongside the new volumes section.

Reads $XDG_CONFIG_HOME/slocker-lite/config.yaml (falling back to
$HOME/.config/slocker-lite/config.yaml), organized into sections. Only
the "global" section's log-level is supported for now -- other options
are one-shot flags, not standing preferences. An explicit --log-level
on the command line always overrides the config file, the same way
SPDLOG_LEVEL already does.
Uses libyaml directly (yaml_dep was already declared in meson.build but
unused). A missing config file isn't an error; unknown sections/keys
are ignored for forward-compatibility; malformed YAML syntax is a hard
error.
