refactor: use structured media delivery

ClawSweeper #84247 review round 2:

P1 (security, high): neutralize line-start MEDIA: directives in vision descriptions
before wrapping with wrapExternalContent. The agent media extractor scans every
browser tool-result text block via splitMediaFromOutput which treats line-start
MEDIA: as a trusted local-media delivery directive, and browser is on the
trusted-media allowlist. Without neutralization, page or vision-provider output
containing 'MEDIA:/tmp/secret.png' could synthesize a channel-deliverable media
artifact from untrusted content. wrapExternalContent itself does not strip
line-start directives. Introduce neutralizeMediaDirectives in vision.ts that
prepends '[neutralized] ' to any line whose trimStart() begins with MEDIA:
(case-insensitive), defanging the parser anchor while keeping the original
text human-readable.

P2 (compatibility): pass resolveRuntimeImageSanitization() to imageResultFromFile
in the vision-failure catch fallback. The non-vision screenshot path already
forwards this option (d5cc0d53b7) so configured agents.defaults.imageMaxDimensionPx
takes effect. Without this fix, any provider timeout/error silently bypasses the
sanitization guard and returns a raw full-resolution screenshot.

Regression coverage:
- vision.test.ts: 6 unit cases for neutralizeMediaDirectives (no-op fast path,
  mid-line MEDIA: untouched, line-start defanged, leading-whitespace defanged,
  case-insensitive, multiple directives per blob).
- browser-tool.test.ts: 2 integration cases that drive the full screenshot
  tool execute path:
    - 'neutralizes MEDIA: directives in vision text and does not attach media'
      asserts no line matches /^\s*MEDIA:/i in returned text, secret path text
      is preserved verbatim, details.media is absent, and imageResultFromFile
      is not called on the success path.
    - 'preserves screenshot image sanitization on vision failure fallback'
      mocks describeImageFileWithModel to reject and asserts the fallback
      imageResultFromFile call receives imageSanitization: {maxDimensionPx:1600}
      plus the 'browser screenshot vision failed' extraText.

+### Screenshot vision (text-only model support)
+
+When the main model is text-only (no vision/multimodal support), browser
+screenshots return image blocks that the model cannot read. Browser screenshots
+reuse the existing image-understanding configuration, so an image model
+configured for media understanding can describe screenshots as text without any
+browser-specific model settings.
+
+```json5
+{
+  tools: {
+    media: {
+      image: {
+        models: [
+          { provider: "bytedance", model: "doubao-seed-2.0-pro" },
+          // Add fallback candidates; first success wins
+          { provider: "openai", model: "gpt-4o" },
+        ],
+      },
+      // Shared media models also work when tagged for image support.
+      // models: [{ provider: "openai", model: "gpt-4o", capabilities: ["image"] }],
+    },
+  },
+  agents: {
+    defaults: {
+      // Existing image-model defaults are also honored.
+      // imageModel: { primary: "openai/gpt-4o" },
+    },
+  },
+}
+```
+
+**How it works:**
+
+1. Agent calls `browser screenshot` → image captured to disk as usual.
+2. The browser tool asks the existing image-understanding runtime whether it
+   can describe the screenshot using configured media image models, shared media
+   models, image-model defaults, or an auth-backed image provider.
+3. The vision model returns a text description, which is wrapped with
+   `wrapExternalContent` (prompt injection guard) and returned to the agent
+   as a text block instead of an image block.
+4. If image understanding is unavailable, skipped, or fails, the browser falls
+   back to returning the original image block.
+
+Use the existing `tools.media.image` / `tools.media.models` fields for model
+fallbacks, timeouts, byte limits, profiles, and provider request settings.
+
+If the active main model already supports vision and no explicit image
+understanding model is configured, OpenClaw keeps the normal image result so the
+main model can read the screenshot directly.
