Allow local version mismatches when validating lockfile

Summary

Closes #12282.

Test Plan

Given:

[project]
name = "foo"
version = "0.1.0"
description = "Add your description here"
readme = "README.md"
requires-python = ">=3.13.0"
dependencies = ["flash-attn"]

[tool.uv]
environments = ["sys_platform == 'darwin'", "sys_platform == 'linux'"]
constraint-dependencies = ["torch==2.5.1"]

[tool.uv.sources]
flash_attn = [
  { url = "https://github.com/Dao-AILab/flash-attention/releases/download/v2.7.3/flash_attn-2.7.3+cu12torch2.5cxx11abiFalse-cp310-cp310-linux_x86_64.whl", marker = "sys_platform == 'linux' and python_version == '3.10'"},
  { url = "https://github.com/Dao-AILab/flash-attention/releases/download/v2.7.3/flash_attn-2.7.3+cu12torch2.5cxx11abiFalse-cp311-cp311-linux_x86_64.whl", marker = "sys_platform == 'linux' and python_version == '3.11'"},
  { url = "https://github.com/Dao-AILab/flash-attention/releases/download/v2.7.3/flash_attn-2.7.3+cu12torch2.5cxx11abiFalse-cp312-cp312-linux_x86_64.whl", marker = "sys_platform == 'linux' and python_version == '3.12'"},
  { url = "https://github.com/Dao-AILab/flash-attention/releases/download/v2.7.3/flash_attn-2.7.3+cu12torch2.5cxx11abiFalse-cp313-cp313-linux_x86_64.whl", marker = "sys_platform == 'linux' and python_version == '3.13'"}
]

Ran uv lock on v0.6.5. Then verified that uv lock fails on v0.6.6 on the same lockfile, but this commit succeeds.

nit: if version.without_local() != &wheel.filename.version.without_local() to be fully permissive?

[charliermarsh]

I don't think we want to allow mismatching locals -- we don't do that elsewhere, at least? I think it would error elsewhere, like when we install.
