feat(config): modes - a mode is an artifact kind, the lenses it runs and its effort
The config defines the modes (modes.<name>): the kind of artifact the mode
reviews - reply, series or commits, the three shipped partitions; a kind
is a mode of its own name - the lenses it runs, in its kind's gate order,
and the effort it runs at, else the kind's default (max for a reply or a
series, xhigh for a commit range). `run --mode` names any of them, the
dump records mode and kind, and everything that decided by the mode's
name - the partition and hash, the prompts, the schemas, the disposition
and reuse-key rules, what the CLI requires - decides by the kind.

Every lens stays off until a mode lists it; lenses.<name>.run is retired
with a warning that says so, and a lens of another kind, a name that is
no lens, a lens listed twice and an unknown effort are config problems.
The defaults run no lens; the template ships the three kinds as modes
with every lens of their kind at the kind's effort, to trim (the owner's
ruling of 2026-11-01), and init says so as it writes it - a kept config
is the repository's own, and only one that lists no lens gets a step.

The readers of the retired key follow: the CI smoke config, the shipped
skill, the procedure (its description of the config as well as its
mechanics), the manifest template, the run's messages and the comments
that named the three modes. The run lock, the run numbers and the dump
names are the kind's, so one full run per hash holds across the modes
of a kind and their rounds count on together; the dump says which mode
ran. The database broker starts for a lens the mode runs, as every other
reader of the lenses off reads them. A named mode runs through the CLI
in the kernel-modes test.
