feat: drop the kettle plugin; the binary writes its own skills

Browse Source 
The plugin and the binary shipped on two release cadences and nothing on an
operator's machine ever checked that the one they installed described the other.
The generated flag block existed precisely so a renamed flag could not ship with
documentation recommending the old one — and then shipped one version behind the
registry it came from, which is the same bug one hop downstream.

So the prose moved into the binary. `internal/scaffold` embeds every document;
`kettle init` and `kettle gen scaffold` write them into a project's own
`.claude/`. The two cannot disagree because there is one artefact.

The namespace survived the move. A project's skills are flat, so the prefix is
spelled into the directory name (`kettle-issue`); a project's *commands* take
their namespace from a subdirectory, so `commands/kettle/init.md` is still
`/kettle:init`. Four of the six command files are thin pointers at a skill, and
that is what kept ~1,600 lines of `/kettle:…` cross-references true without a
rewrite. `init` and `auth` lost `disable-model-invocation: true` — being a
command is that property — and `auth` now restricts `allowed-tools` so a model
cannot reach `kettle auth add` at all.

`gen scaffold` writes files whole rather than splicing a region. The old
refusal protected somebody's hand-written prose around the block; that prose is
embedded now, so there is none to protect, and preserving local edits would
freeze a project's documentation at whatever version first initialized it.
`--check` warns before an upgrade discards one.

The plugin's `agents-sync.sh` — 141 lines of Python behind a filename that said
`.sh` — became `internal/mirror` and `kettle mirror`. Same seven branches, same
refusal to merge two real files that differ, now with a table test per branch
and a check that a repair converges in one pass. `--hook` is the PreToolUse
form and exits 0 on every path including a panic. It is opt-in per project,
which is strictly narrower than the plugin hook that was on for everybody who
installed it.

`kettle init --interactive` walks a person through the login, the token (read
with the echo off, so it lands in no history and no file), the repository, the
`.claude/` tree and the mirror hook. It refuses a stdin that is not a terminal
and names the flags instead: every question it asks has one, and it performs
nothing itself, so an interactive run and a flag run are one code path.

Two rules that used to be prose are now the binary's: init refuses a linked
worktree and names the main checkout, and writing into an existing
`.claude/settings.json` is refused with the snippet printed rather than
reformatting a file the operator commits.

The scaffold version stamp went to its own `.kettle/scaffold.yaml` rather than
into `config.yaml`, because unknown keys there are a hard error and that file
may be committed and read by whatever build each machine has.

golang.org/x/term becomes a direct dependency; it was already in the tree
indirectly, so no module was added.

Short: "keep CLAUDE.md a symlink to AGENTS.md in every directory below here",
Long: `Two agent harnesses read two different filenames for the same document. A
repository that keeps both as real files keeps TWO DOCUMENTS, and they drift —
silently, until somebody reads the stale one and believes it. This walks a tree
and leaves one arrangement behind everywhere:
AGENTS.md is the real file; CLAUDE.md is a symlink pointing at it.
The link is relative, so a tree that is moved, copied or cloned keeps working.
AGENTS.md is the real one because the convention is not one vendor's: a
repository that names its documents after a single tool has picked a side it did
not need to pick.
NOTHING HERE DELETES CONTENT. Six of the seven states it can find are repaired
losslessly — a missing link is created, a reversed layout is swapped round, a
duplicate whose bytes match its original is replaced by the link. The seventh,
two real files whose contents DIFFER, is reported and left exactly as it was:
one of them is somebody's writing and no rule here knows which.
It walks the directory given, or the working directory. node_modules, vendor,
venv, __pycache__ and every dot-directory are skipped, because somebody else's
tree is somebody else's business.
--hook is the PreToolUse form: it reads the hook payload on standard input,
writes any report back as additionalContext, and ALWAYS EXITS 0 — including when
it fails. A tool that broke somebody's Bash call because its documentation
helper crashed would be worse than no tool. --check is the opposite end: it
writes nothing and exits 1 when the tree is not canonical, which is what a
pre-commit hook or a make target calls.
` + "`kettle init --interactive`" + ` offers to register the --hook form in
.claude/settings.json. It is offered rather than assumed: this is one
repository's documentation convention, and a project that does not keep AGENTS.md
files wants nothing to do with it.`,
