The aside button could hit `subagent/unauthorized: subagent mode does not
match the supplied address`. The host's session-controller (dsh-api-session-
controller validateAddress) compares the `mode` in the resource address
against the child's durable descriptor mode and rejects any mismatch. The
address `mode` came from the row, and on the degraded path the row's mode is
a best-effort guess from the summary `running` flag (running => continuable)
— so a child that is genuinely one-shot but still running was guessed as
continuable and the very open it was meant to trigger 401'd.
Two layers, so it holds on both the real-catalog and the degraded path:
- subagentChatAddress: only pass a mode through when it is one of the two
durable values (`one-shot` / `continuable`). Anything else is omitted,
which the controller reads as `mode: "unknown"` and therefore skips the
comparison — the safest form when the caller does not actually know.
- openChildAside: prefer the host's real descriptor mode for the child
(the `subagentsByParent` entry carries the durable mode) over the address
mode, falling back to the address only when the real catalog never arrived.

The host's own catalog puts an "open beside" action on every non-current
child row; this port had never wired it. Add it: the row grows a hover
button that opens the child's chat as a `subagentchat` resource in the
native right Sidebar, so a user can watch a child work without giving up
the pane he is in (the in-pane jump stays the plain row click).
- src/client/native/subagent-chat.ts: the resource-address codec, copied
from @deepseek-ai/dsh-client-ui-subagent rather than imported (the
package exports no helpers and the plugin must not reach into it).
- native/surface.ts: carry `kind` / `preferNewPane` on an open.
- SubagentView: `openChildAside` via `ctx.get?.('sidebarRight')` — an
optional probe, since a fake ctx without `get` otherwise crashes the
whole render (9 specs caught it) — threaded through all three
CatalogRows call sites.
- locales: `subagentOpenAside` in zh/en plus all 20 third-language
dictionaries (tests/locales.spec.ts enforces key-set parity).
- docs: the conventions page now documents the resource-open recipe.
Gates: typecheck / lint / build / test 132 files 1390 passed /
check:consumer-types, plus the repo's runtime-contract symbol check.
