feat(custom-widgets): harden AI authoring (credential redaction, JSX policy)

Carve the custom-widget AI-authoring hardening out of #6691 into its own
change, independent of the widget/integration architecture refactor:

- add definition-security redaction helpers that strip credentials/URLs from
  the AI context, response, and generated text
- tighten the authoring prompt and examples
- enforce Tabler icon prop policy in the JSX analyzer
- expand ai-prompt, jsx-policy, and evaluation test coverage

Self-contained in @homarr/custom-widgets; no dependency on the metadata
catalog work. Typecheck + 490 package tests pass.

-# Homarr Local Harness
-
-Use this skill when a Homarr change needs a real production image and browser validation. Work from the repository root and keep the harness name Docker-safe, such as `feature-board`.
-
-## Set up the harness
-
-Run the TypeScript operations CLI; this workflow does not use the interactive developer TUI:
-
-```sh
-pnpm cli harness setup feature-board
-```
-
-`setup` builds the current checkout as `homarr:feature-board`, replaces the named harness container, and starts it with a persistent data volume. It enables demo mode, mock integrations, and writable demo mutations by default:
-
-- `DEMO_MODE=true`
-- `DEMO_READ_ONLY=false`
-- `UNSAFE_ENABLE_MOCK_INTEGRATION=true`
-
-Pass repeatable environment overrides when the feature needs them:
-
-```sh
-pnpm cli harness setup feature-board \
-  --env WORKSHOP_WEB_URL=https://example.test \
-  --env FEATURE_FLAG=true
-```
-
-Use `pnpm cli harness build <name>` when only the image is needed, and `pnpm cli harness run <name>` to start an already-built image. `--port <number>` pins a host port; otherwise Docker assigns one.
-
-Always use the URL printed by the command. If the output is no longer available, query it directly:
-
-```sh
-pnpm cli harness port feature-board
-```
-
-Do not assume port `7575`; the container listens on `7575`, but the host port is dynamic by default.
-
-## Browser validation
-
-Open the printed URL with the environment's `browser-harness` tool. In this workspace, the `agent-browser` CLI is the supported browser automation fallback. Load its current workflow before invoking it:
-
-```sh
-agent-browser skills get core
-```
-
-Navigate to the exact harness URL, wait for the app to become usable, exercise the changed flow, and capture screenshots or other browser evidence. Keep browser state in a named session when the workflow needs login persistence. Report the exact URL, viewport/session used, and screenshot paths; a Docker process or HTTP health response alone is not browser acceptance.
-
-## Cleanup
-
-Stop the named container when finished:
-
-```sh
-pnpm cli harness stop feature-board
-```
-
-Stopping keeps the data volume so the same harness can be restarted. A later `setup` rebuilds the image and replaces only the container. Preserve unrelated containers, images, volumes, and working-tree changes.

-The bookmarks widget allows you to display multiple links in a single widget.
-Select one or more existing Apps directly in the widget settings; these bookmarks keep a reference to the App, so changes to its name, icon, or URL are reflected automatically.
-For links that do not need an App, add their URLs under **Custom links** instead.
-Its normal view adapts each configured layout to the available width and height: lower-priority hostnames are hidden before names or icons, and larger collections scroll instead of crushing cards.
-Advanced view shows every bookmark as a roomy card with its full title, hostname, icon, and complete description regardless of the compact layout and visibility choices.
+The bookmarks widget keeps direct URLs and Homarr Apps in one ordered list.
+Paste a URL and press Enter, paste several comma-separated or one-per-line URLs, or search for an existing App.
+URLs do not need an App record; Homarr uses the site's favicon and falls back to a link icon when it cannot load one.
+Bookmarks selected from Apps continue to use the App name, URL, icon, and description.
+
+**Adaptive** layout is the practical default: it changes between icons, compact rows, and tiles as the widget changes shape. Every compact item exposes its destination on hover, while advanced view expands items into descriptive cards.

-First call customWidget_getSkill. Its single lazy response contains the complete installed SKILL.md and every bundled reference; follow all of it. Read the live schema and compact component catalog. Fetch only the named component and example resources needed for the design. Component resources contain component-specific props; if shared props are needed, collect their catalog names and fetch those docs together once with customWidget_getSharedProps. The live resources are authoritative for this Homarr release.
+Mandatory sequence — follow it exactly:
+1. First call customWidget_getSkill and follow the complete installed skill and bundled references.
+2. Call customWidget_schema, then customWidget_getComponentCatalog.
+3. If a complete example is useful, call customWidget_getExample before any customWidget_getComponent call. Then choose at most four component names total and never request a fifth. Fetch only those named docs and, once, any named shared props with customWidget_getSharedProps.
+4. Before validation, quickly reject IIFEs, new, block callbacks or => {, and raw HTML tags such as span; use catalog components instead. Immediately call customWidget_validate with the complete definition and repair every issue.
+5. Call customWidget_previewCreate with that exact validated definition.
+6. Call customWidget_previewQuery once for every query returned by the preview and inspect every response.
+7. Call customWidget_createFromPreview with the exact fully tested preview session ID.
+
+Make one documentation tool call at a time. Never issue batched customWidget_getComponent calls, speculate about components, or walk the catalog. If preview evidence requires a definition change, restart at step 4 with the revised complete definition. The live resources are authoritative for this Homarr release.
 
 Keep the documentation phase bounded. Fetch at most eight named component documents before the first validation, or at most four after loading a complete example. Fetch another component only to resolve a concrete validation issue or missing interaction; never walk the catalog component-by-component. Move promptly from the smallest sufficient documentation set to a complete customWidget_validate call.
 
-Follow this lifecycle without skipping steps: construct one credential-free definition; call customWidget_validate; repair every reported issue; call customWidget_previewCreate; call customWidget_previewQuery once for every query returned by that preview (supplying required manual parameters); inspect the real response shape and HTTP status; adjust paths and template bindings; validate and preview again after changes; open or provide the returned previewPath for visual review; only then call customWidget_createFromPreview with the exact final tested preview session ID. Use customWidget_create only when no reusable preview session exists. Prefer templateLines over a JSON-escaped template string for multiline JSX in validate and preview tool inputs.

Use customWidget_create only when no reusable preview session exists. Prefer templateLines over a JSON-escaped template string for multiline JSX in validate and preview tool inputs.
 
 Do not claim a query works when it has not returned a successful preview response. Configure deployment-specific source URLs and request credentials through Homarr when needed; never repeat plaintext. Use simulated preview actions unless the user explicitly enables live preview actions.
 
-Treat preview data as the binding contract: render every core requested field, guard optional arrays and nested values before indexing, and do not silently drop returned items. Show concise freshness context when the response supplies a timestamp. Give recoverable load errors and empty states a clear refresh or retry path.
+Treat preview data as the binding contract: render every core requested field, guard optional arrays and nested values before indexing, and do not silently drop returned items. Show timestamps as concise human-readable absolute dates and times; do not compute relative time with Date, Date.now, or Date.parse unless the live docs provide a safe helper. Give recoverable load errors and empty states a clear refresh or retry path.
 
 Use the lean keyed sources, requests, and options contract. Bind saved values directly with $option and invocation values with $param. Load queries cannot use $param. Keep the design responsive, accessible, theme-safe, loading-aware, empty-aware, and error-aware.
