Yichen Jiang 5ed79887fb fix(web): correct the preset-layer contracts review found stale
None of these change behavior; each said something that was not true.

`SessionCwdConflict`'s doc block had been left stranded above the
`AgentPresetConflict` inserted under it, so one class carried a comment
about the other and the second carried none.

The roster comment named a `.system` directory that does not exist; the
shipped root is `config/agent-presets/`, and `system` is the trust its
entries carry.

The real-composition test attributed the disabled `api-gateway` row to
"side effects outside this process" alongside the port and the exporter.
It is disabled for a different reason — the api-proxy cannot mount in
this layer at all — and hiding that behind the same phrase would leave a
later layer unable to tell whether the line can come out.

One test claimed to refuse an adoption while asserting only that the
header records the preset; it now says what it checks.

`PERSONA_SECTION`/`PERSONA_ORDER` existed twice, once in the registry
that declares the slot and once restated in the row that replaces it —
a drift that would land a preset's persona beside the deployment's
instead of shadowing it. The registry exports them now.

The preset conflict message read "already runs agent preset undefined"
for a session that records none, which is the shape a deployment with no
roster produces; it names that case instead, with the regression that
reaches it through the gateway.

Finally, `PresetTree.write()` drops the `loader/config-update` the
inherited method emits — recorded on the override, since a future
edit-while-running flow needs its own persistence path.

/**
* A per-agent persona as a composable row.
*
* `dsh-system-prompt` owns the global persona as its own config, and registers
* that section unconditionally — so this row is **scope-only**. Mounted inside
* an agent preset it shadows the deployment persona for that one session,
* exactly like the per-child persona `dsh-subagent` installs; mounted globally
* it collides with the registry's own registration and fails loud.
*
* That constraint is the reason the row exists. An agent preset cannot mount
* the prompt registry itself, so without a row of its own a preset could
* change an agent's tools but never its identity.
* @module @deepseek-ai/dsh-persona
