Move the MCP bridge into the ldk-server workspace and switch it to an in-tree client dependency so workspace builds and tests cover it directly.

Did a quick skim and ran through codex

Codex Review:

  - [P2] Honor storage.disk.dir_path when resolving credentials — /home/ben/projects/ldk-server/ldk-server-mcp/src/
    config.rs:57-60
    If the shared ldk-server config uses a custom storage.disk.dir_path, this parser drops that section entirely, so
    resolve_config() can only look in ~/.ldk-server/... for api_key and tls.crt. In deployments that store node state
    outside the default directory (a setup ldk-server-cli already supports), the MCP bridge will fail to authenticate
    unless users also set both LDK_API_KEY and LDK_TLS_CERT_PATH by hand.
  - [P2] Fall back to the default gRPC address when no base URL is configured — /home/ben/projects/ldk-server/ldk-
    server-mcp/src/config.rs:112-116
    In setups that rely on the standard 127.0.0.1:3536 gRPC address and only use the default credential files on disk,
    this path exits with “Base URL not provided” instead of using the same default as ldk-server-cli. As a result, ldk-
    server-mcp cannot start in the zero-config case unless users create a config file or export LDK_BASE_URL, even
    though the server is running at the normal address.

I think these are two things we fixed in the cli since you created the MCP server.

Support storage.disk.dir_path config and fall back to the default gRPC
address when neither LDK_BASE_URL nor a config file is present, matching
the behavior of ldk-server-cli.

Fix clippy needless_borrows_for_generic_args in test.

Co-Authored-By: HAL 9000
Move routing and invoice default constants into ldk-server-client so
they are shared between ldk-server-cli and ldk-server-mcp.

Use the workspace-built MCP binary directly in tests and add focused helper coverage for argument parsing so regressions are caught without requiring a live server.

Co-Authored-By: HAL 9000
Build the MCP binary in the e2e harness and exercise its stdio protocol against a live ldk-server so basic MCP functionality is verified without involving an agent.

Co-Authored-By: HAL 9000
Drop the tests/ directory from rerun-if-changed since test changes
don't affect the mcp binary.

Run MCP-specific formatting, clippy, and crate tests in a dedicated workflow and add a separate job that exercises the MCP e2e sanity suite on Ubuntu.

Co-Authored-By: HAL 9000
Remove redundant formatting check (already covered by the main CI
workflow) and drop the MCP e2e job (already covered by the e2e-tests
workflow).

Co-Authored-By: HAL 9000
Describe the MCP bridge as a first-class workspace member and document how to build, test, and sanity-check it alongside the rest of ldk-server.

Replace exhaustive tool listing with a pointer to tools/list to avoid
the maintenance burden of keeping the README in sync with every new RPC.
