Build fails because dependency references deleted Git branch (feat/us-dc-region)

[01xRiverse]

Description

Attempting to build the project fails because the longbridge dependency in Cargo.toml references a Git branch that no longer exists:

longbridge = { git = "https://github.com/longbridge/openapi.git", branch = "feat/us-dc-region" }

Cargo reports:

failed to get `longbridge` as a dependency

Unable to update https://github.com/longbridge/openapi.git?branch=feat/us-dc-region

failed to find branch `feat/us-dc-region`

cannot locate remote-tracking branch 'origin/feat/us-dc-region'

Environment

• macOS (Apple Silicon)
• Latest stable Rust toolchain

Expected behavior

The project should build successfully after cloning the repository.

Actual behavior

The build fails because the dependency points to a Git branch that no longer exists in the longbridge/openapi repository.

Suggested fix

Update the dependency to a valid branch, tag, or commit in the longbridge/openapi repository so new contributors can build the project successfully.
