uv build fails with "No such file or directory" when building generated clients because the pyproject.toml references a CHANGELOG.md file that is never created.

Changes

• UV template: Removed data = ["CHANGELOG.md"] from [tool.uv.build-backend] section
• Poetry template: Removed "CHANGELOG.md" from include array
• Test fixtures: Updated 6 snapshot and golden-record files to match new template output

Example

Generated clients now produce clean pyproject.toml files:

# UV
[tool.uv.build-backend]
module-name = "my_client"
module-root = ""

# Poetry
include = ["my_client/py.typed"]

Previously, these would include data = ["CHANGELOG.md"] and include = ["CHANGELOG.md", "my_client/py.typed"] respectively, causing build failures.

<issue_description>Describe the bug
uv build crashes:

Building source distribution (uv build backend)...
Building wheel from source distribution (uv build backend)...
  × Failed to build `/path/to/client`
  ├─▶ Failed to walk source tree: `/Users/emil/.cache/uv/sdists-v9/.tmphKI5f2/client-2.64.0/CHANGELOG.md`

  ╰─▶ No such file or directory (os error 2)

Probably related to this part in pyproject.toml:

[tool.uv.build-backend]
module-name = "arboair_microservice"
module-root = ""
data = [
    "CHANGELOG.md",
]

But there is no changelog.md generated.

@dbanty Weird, don't know why that's in there 😅. Looks like it's in the Poetry template too. We should remove it from both.
