compat: narrow the support matrix to dsh 0.1.2-rc.1+

The install/runtime compatibility floor moves from 0.1.1-rc2+ and 0.1.2-alpha2+ to 0.1.2-rc.1+. The 0.1.1 line and the 0.1.2-alpha previews leave the support matrix, so every pre-0.1.2 fallback they existed for is removed outright: - client history: drop the legacy `connection.api.sessions.history` face, the `result`-nested envelope, and the `events` rows field — the gateway `remote.session.page` face and its ClientResult envelope are the only served shapes. - client image loader: drop the pre-0.1.2 `conversation.resolveImage` face; `uiConversation.imageUrl` only. - client node join: drop the pre-0.1.2 `useSession.nodes` seat; `useChat`'s ChatSnapshot `legacy.nodes` only (UseSessionLike removed). - tests/baselines.ts: single baseline `v0.1.2-rc.1`; HostSeam dropped (the registry generation hard-codes header-passing init and seq-0 eager seeding, now mirrored with the exact `init(header, inheritedEventCount)` arity); ClientSeam slimmed to the consumed probes. - deps: devDeps re-pinned to the 0.1.2-rc.1 generation (types compile against the real rc.1 surfaces); cordis ^4.0.2 and schemastery ^3.18.2 per the rc.1 peer requirements; dsh-scope/dsh-invariants declared as dev deps; peer floors >=0.1.2-rc.1; dshReleases table trimmed. - release workflow fetches only the dsh-v0.1.2-rc.1 tag; docs updated (AGENTS.md, README, docs/compatibility.md). - verified against the rc.1 sources: the tool-attribution map (names and packages, incl. the documented `subagent_fork` alias), MCP naming, the page/imageUrl/legacy.nodes faces, and the registry contract.

 ## What each check means

 - **Automated seam matrix** — part of this repository's `pnpm test` (the `compat` vitest project). For every baseline tag it stages the harness's REAL sources at that tag, boots the plugin's built host entry into that tag's actual `SessionProjectionRegistry` on the cordis release the line vendors, and probes the tag's client seams (slots, finalized-nodes seat, image loader, history face/envelope, markdown chrome, platform module table, durable-event vocabulary, settings namespace). Definitions live in `tests/baselines.ts`; the release workflow fetches the pinned baseline tags before testing.
