SEO init (#4197)

# Description of Changes
This pull request introduces dynamic document meta tag management and
improves URL routing and tool metadata handling in the frontend. The
most significant changes are the addition of a custom hook to update
document meta tags (including OpenGraph tags) based on the selected
tool, enhancements to the tool selection context for better URL
synchronization, and enrichment of the `Tool` type and tool registry
with more metadata.

**Dynamic document meta management:**

* Added a new `useDocumentMeta` hook that updates the page's `<title>`,
description, and OpenGraph meta tags based on the currently selected
tool, and restores the original values on cleanup.
(`frontend/src/hooks/useDocumentMeta.ts`)
* Integrated `useDocumentMeta` into `HomePageContent` so the document's
meta tags dynamically reflect the selected tool's metadata, improving
SEO and social sharing. (`frontend/src/pages/HomePage.tsx`)

**Tool metadata and context improvements:**

* Enhanced the `Tool` type and tool registry to include `title` and
`description` fields, which are now translated and used throughout the
UI and meta tags. (`frontend/src/types/tool.ts`,
`frontend/src/hooks/useToolManagement.tsx`)

* Updated the `ToolWorkflowContext` to use the new `Tool` type for
`selectedTool`, replacing the previous `ToolConfiguration` type.
(`frontend/src/contexts/ToolWorkflowContext.tsx`)

**URL routing and synchronization:**

* Implemented logic in `ToolWorkflowContext` to synchronize the selected
tool with the browser URL, initialize tool selection from the URL on
load, and handle browser navigation (back/forward) for tool selection.
(`frontend/src/contexts/ToolWorkflowContext.tsx`)
