The supervisor reports the child's pid the moment it is spawned, before it
answers, so a server killed during a start still leaves a pid that names the
runtime as ours. stop() takes that stored pid (previousPid) and ends a
runtime an earlier server left behind when its command line is a binary
under our runtime folder, so no caller deletes the folder under a live
process. start() takes a version: an installed model keeps the runtime
version it was installed with when a later build pins another one.
removeLocalModelFiles() refuses a local-model folder that is itself a
symbolic link (every check compared against the real path of the root, so
a link in its place passed whatever it pointed at). removePartialModelBlobs()
deletes what an interrupted download left in the model store, which the
runtime answers "not found" for and never deletes.

The types, the module skeletons and the test fake that let the runtime, the
install job and the window be built at the same time.
Types:
- src/types/local-model-install.ts (new): the runtime pin, the install
states, steps and error codes with one sentence and one next step each,
the progress, the `install` object of GET /api/local-model, the bodies and
409 answers of the install verbs, the state file. `LocalModelStatus` moves
here; `install` is optional until the route emits it.
- src/types/local-model.ts: the catalogue row's Mac memory figures, the
measured speed of a tested entry, the `measured` budget source,
`RecommendOptions`, and the row tag, the coding agents and the install
total of a candidate. All optional until the catalogue and `recommend()`
carry them, so the read-only stage keeps compiling and its tests stay
green.
Modules with final signatures and bodies that throw:
runtime.ts (the compiled pin is final), ollama-client.ts, developer-tools.ts,
state-store.ts, install-job.ts (the state, step and transition tables are
final), connect.ts, custom-model-hosts-writer.ts, cli-install-runner.ts.
Nothing imports them yet, so the server is unchanged.
Implemented: paths.ts (every folder of the feature, from dataPath()), and
`modelFitsBudget()` in recommend.ts, the judgement the job makes with the
measured budget before it downloads a model. `recommend()` takes the options
parameter and does not read it yet.
Test fake: test/fixtures/fake-ollama.ts, a runtime on a port the system
picks, in the shapes measured on a Mac: version, tags, ps, the pull stream
(MLX and GGUF lines, an error line, a cut stream, a resumed pull), chat with
and without a tool call, the model list, a runtime archive with Range
support, and a fake child process that logs the device total.
