Backport of #58427 and #58560 from beta.

Problem

Tool results can carry screenshots as inline data: files. The store kept every one as base64, so a long session with browser or computer-use tools held hundreds of MB, even in a client that never shows those images.

Change

• omitToolFileData option on createData: off by default. When set, inline data: files in tool results become an empty data:<mime>;base64, URI, so the item still says what it was. file: and other URIs are untouched.
• Where it applies: live session.tool.success and session.tool.failed events, and fetched message pages.
• Memory detail (fix(app): stop omitted tool images from keeping their payload alive #58560): the empty URI is built from mime, not sliced from the original, because a V8 sliced string keeps the whole payload alive.

No client turns it on yet. The desktop sets it with the beta desktop merge; the TUI is unchanged.

Testing

• typecheck:tsc passes in client, tui and app.
• New client/test/solid-data.test.ts case: fetched and live tool results drop inline data: payloads and keep other files. It passes with client/test/solid-refresh.test.ts.

Public API: adds the optional omitToolFileData option to createData in the client package (off by default, backwards compatible)

Looks good. When omitToolFileData is set, inline data: payloads are dropped in every path that puts tool results into the store: the live session.tool.success/session.tool.failed events and both message fetch paths (first page and older pages). The only other fetched message, the model-switched reload, has no tool content. file: URIs are left alone. I ran the new test in solid-data.test.ts together with solid-refresh.test.ts (both pass), checked that the new test fails on the base, and ran typecheck:tsc in client and tui (both pass).

Public API: adds an optional omitToolFileData option to createData in @opencode/client. It is off by default, so it is backwards compatible.
