Bump eca-webview and wire global-config + logs IPC stubs

The webview now embeds a CodeMirror-powered Global Config editor
(new Settings → Global Config tab) and the Logs tab, both of which
add new host↔webview messages. Because eca-web compiles the
webview sources inline (via the `@webview` Vite alias + tsconfig
`include`) rather than consuming a prebuilt bundle, any new runtime
dep the webview picks up must also be mirrored in eca-web's own
package.json for Vite/Rollup to resolve at build time — otherwise
the build fails with "Rollup failed to resolve import
@codemirror/state". This commit mirrors the six @codemirror/*
packages plus jsonc-parser.

The new messages are sent via webviewSendAndGet, which blocks on a
matching requestId reply for up to 30 s. A browser has no local
filesystem and no local log buffer, so we reply immediately with
error-shaped payloads and let the tabs render a graceful "not
available in the web client" state instead of spinning. The two
fire-and-forget messages (logs/clear, logs/openFolder) are silent
no-ops. All five cases are moved out of the
`// Ignored (no web equivalent)` fallthrough block into explicit
branches so the intent — and the future extension points for
remote-log streaming — stay visible.

Submodule bump also brings in Hero-mode polish, live
server-startup progress, MCP add/remove, and the Settings tab-bar
horizontal-scroll fix.
