fix: return binary files as MCP embedded resource instead of BASE64 prefix fixes #9 6ee26f1ad8

The previous implementation prefixed base64 with "BASE64:" in a text
response. This updates the response to use the proper MCP embedded
resource format:

  { type: "resource", resource: { uri, mimeType, blob } }

Changes:
- types.ts: extend ToolOutput content union to allow resource items
- file-operations.ts:
  - getMimeType() maps common extensions to MIME types, falling back
    to application/octet-stream
  - MIME_TYPES table covers PDF, ZIP, images, Office formats, audio/video
  - Binary files are now returned as an EmbeddedResource with:
      uri:      obsidian://<vault>/<path>
      mimeType: detected from file extension
      blob:     base64-encoded raw bytes from the Buffer
  - Tool descriptions updated to document the resource response shape

fix: return images as MCP image content type per spec cef658ce19

Images (PNG, JPG, GIF, WEBP, SVG) now returned as { type: 'image', data, mimeType }
per https://modelcontextprotocol.io/specification/2025-11-25/server/tools#image-content
Other binary files continue using embedded resource format { type: 'resource', ... }
Added audio content type to ToolOutput union for future use

feat: add HTTP server transport for MCP 8b651d379a

Adds src/http-server.ts - a Node.js HTTP entry point that exposes the
MCP implementation via Streamable HTTP transport (POST/GET /mcp) per
the MCP 2025-11-25 specification.

- Uses StreamableHTTPServerTransport (stateless mode) from the MCP SDK
- Port configurable via MCP_PORT env var (default: 3000)
- ObsidianMCPServer.connect() now accepts an optional Transport param
  so both stdio (existing) and HTTP (new) modes reuse the same server
- Added 'npm run server' script to start the HTTP server

fix: read binary files via native FS instead of Obsidian CLI 76b4aed508

The Obsidian CLI does not support binary file output, causing corrupted
or empty results for images, PDFs, ZIPs, etc.

New approach for binary files (known MIME type from extension):
- Run 'obsidian vault info=path' to get the vault root filesystem path
- If 'file' param: run 'obsidian file file=<name>' and parse the 'path'
  field from its output to get the vault-relative path
- If 'path' param: use it directly as the vault-relative path
- Read the file with Node fs.readFile() and return as MCP content

Images -> { type: 'image', data, mimeType }
Other binary -> { type: 'resource', resource: { uri, mimeType, blob } }

Unknown extensions fall through to the CLI with a runtime binary
detection fallback that also uses native FS if triggered.
