3 people 9c7332190c fix: allow whitespace in uv requirement specifiers (#1112) ...

## Summary

When the uv version is read from dependencies (`requirements.txt`, or
`project.dependencies` / `optional-dependencies` / `dependency-groups`
in `pyproject.toml` via `version-file`), the specifier was matched with
`/^uv([=<>~!]+\S*)/`. PEP 508 allows whitespace around operators and
after commas, and those valid forms were misread:

| dependency | before | after |
|---|---|---|
| `uv >= 0.5.0` | not found, latest uv installed | `>=0.5.0` |
| `uv == 0.11.20` | not found, latest uv installed | `==0.11.20` |
| `uv>=0.5.0, <0.6.0` | `>=0.5.0,`, fails with `No version found for
>=0.5.0,` | `>=0.5.0,<0.6.0` |

The regex now allows whitespace around operators and between
comma-separated clauses, and strips it from the result. Inputs that
worked before give the same result, including inline `--hash=` options,
trailing ` # comments`, the `\` continuation lines from `uv pip compile
--generate-hashes`, and names that only start with `uv` (`uvicorn`,
`uv-build`).

## Test plan

- Added cases for spaced operators, spaced clauses, inline `--hash` and
trailing comments. The four whitespace cases failed before the change.
- `npm run all` on Ubuntu (WSL) with Node 24.19.0: build, Biome (no
fixes), packaging, and 165 tests across 15 suites pass. The rebuilt
`dist/setup/index.cjs` only differs in the changed line.
