feat(cli): restore the home-level user patch layer as $DSH_HOME/cordis.patch.yml

The old $DSH_HOME/config.yaml personal overlay returns under the profile
scheme's filename: machine-local preferences that apply to every profile,
loaded after the profile's own cordis.patch.yml (so the home layer outranks
it) and before --patch overlays and flag patches. Both user layers are
hot-reloaded on long-lived surfaces and shown in --dump-config with their
own provenance labels; the built-bin e2e covers the home layer landing live.

User-level machine-local preferences also live in the Harness home:
- **`.env`** — the credential store of [`dsh-credentials-local`](../../credentials/credentials-local/README.md), read by that provider alone. No surface hoists it into `process.env`: doing so would make every stored key look like a read-only launch override on the next run, blocking rotation from the Web settings page. The environment layers are the ambient one and the invoking directory's `.env` (loaded by the bin; `process.loadEnvFile` never overrides), and a composition without the credential provider keeps resolving keys from those alone.
- **`profiles/<name>/cordis.patch.yml`** — the profile's user patch layer, applied after every bundle layer: an id-targeted patch replaces the named entry's whole `config` (restate unchanged fields), `insert` adds entries, and `!!js` expressions interpolate at mount. A patch naming an entry id absent from the composed tree is a stderr warning. An empty or comments-only file throws (it parses to nothing, not to a list); disable the layer with `[]`.
- **`cordis.patch.yml`** (home level) and **`profiles/<name>/cordis.patch.yml`** — the user patch layers, applied after every bundle layer (per-profile first, then the home-level file, which therefore outranks it): an id-targeted patch replaces the named entry's whole `config` (restate unchanged fields), `insert` adds entries, and `!!js` expressions interpolate at mount. A patch naming an entry id absent from the composed tree is a stderr warning. An empty or comments-only file throws (it parses to nothing, not to a list); disable the layer with `[]`.
Long-lived surfaces keep `cordis.patch.yml` live through `watchPersonalPatches`; one-shot runs read only the startup value. The watcher targets the exact path even when the file or immediate parent does not exist, serializes bursts, and recomposes the user patches inside the caller's layer order (bundle layers below, overlay/flag patches above). A rejected read, parse, or Loader candidate leaves the last good tree running and the HMR service broadcasts `hmr/config-update-failed(filename, Error)` after logging it; observer failures are contained. Disposing the context closes the watcher and drains an active refresh.
