Exclude yanked grpcio 1.78.1 and move grpcio-tools to dev dependencies

[Copilot]

grpcio 1.78.1 was yanked from PyPI due to a critical upstream bug (grpc/grpc#41725). This excludes the yanked version while allowing consumers to automatically pick up a fixed upstream release once available.

Changes

• pyproject.toml: Added grpcio>=1.78.0,!=1.78.1,<2.0.0 as a runtime dependency (excludes the yanked 1.78.1, compatible with future fixes)
• pyproject.toml: Moved grpcio-tools to the dev dependency group (it is only needed for protobuf compilation, not at runtime) with the same >=1.78.0,!=1.78.1,<2.0.0 constraint
• uv.lock: Regenerated to reflect the updated dependency constraints

Pull request overview

Pins grpcio / grpcio-tools to avoid installing yanked grpcio 1.78.1 (yanked due to upstream bug), keeping the client usable until an upstream fix is available.

Changes:

• Add explicit grpcio==1.78.0 and tighten grpcio-tools to ==1.78.0 in pyproject.toml.
• Regenerate uv.lock to reflect the 1.78.0 artifacts and updated project dependency metadata.

@copilot implement the two suggestions from code revew. Move the package do dev dependencies and switch the pin to a more graceful != filter.

Done in b0f7742:

• grpcio changed to >=1.78.0,!=1.78.1,<2.0.0 (avoids the yanked version while allowing future fixes to be picked up)
• grpcio-tools moved from runtime dependencies to the dev group with the same constraint (it's only needed for protobuf compilation)
