fix(web): page remote histories and preserve Harness identity - #798
Opening or resuming a large remote Thread can transfer its complete history through Desktop CDP, even when the Thread requires paginated reads. A large response can close that transport and surface as an unrelated remote/offline error. Remote external rows also omit their authoritative Harness identity and render the Codex fallback icon.
Route metadata and five-Turn pages through the same native manager, reuse ChThreadHistory, and resume with excludeTurns before sending. Keep the existing 16 MiB controller response limit and reject oversized responses before CDP serialization; map that typed error without declaring the whole Host offline. Use the locked ws implementation for fragmented multi-megabyte CDP replies. Supplement remote catalog rows with batched ownership/plugin metadata so the sidebar retains the correct Harness identity across history reads.
The native owner, Host/Thread identity, epoch checks, approvals, remote-path isolation, and no-replay write behavior remain unchanged. The controller queries only metadata for icon identity and does not resume or read histories to classify rows.
Validation:
Independent Windows branch: full TypeScript build/test typecheck, ESLint/package boundaries and changed-file formatting passed.
Focused controller/transport/release tests: 14 passed, one platform skip. Web remote session/history tests: 16 passed.
Combined beta.5 candidate using the same remote implementation and official frontend assets: isolated desktop and touch-viewport browser acceptance passed, including history paging, two-Host switching, follow-up, archive/undo, Harness icons and remote-image isolation. The Host/controller/provider data in this browser check are fixtures; no live model was called.
Release Host/controller dependency audits passed for the local candidate. A read-only production Web preflight preserved the running owners and retained the remote/local project catalogs; it does not establish full production activation of this PR.
Additional, unchanged browser suites were attempted: phone-sidebar requires unbuilt source client modules, and two cache-navigation cases timed out waiting for their project row in the packaged-shell setup. Those checks are not reported as passing and their source was not relaxed.
Builds on the merged remote-session support in #771. Does not include the separate broker response-budget or migrated-project fixes.
The remote history paging change looks sound. One test cleanup can hide the real cause of a failure, and two small robustness points are worth considering. Fixing them is low risk and not blocking.

更新基于 operation.metadataOnly 和 error 的错误筛选逻辑，避免使用可能误判无关错误的子串匹配；优先复用现有结构化错误字段判断该错误类型，若没有可用字段，则将消息匹配限制为起始位置的精确锚定匹配。保留其他错误继续抛出的行为。
