Optimize version parsing for common `\d.\d.\d` cases (#20118) ## Summary Version strings in the common `x.y.z` form currently pass through the generic numeric fast parser, including its per-byte loop and segment bookkeeping. This recognizes the exact five-byte form up front, validates the three ASCII digits, and constructs the existing packed representation directly. The packed-value construction is shared with the generic numeric fast path, while every other input continues through the existing parser so normalization and error behavior remain unchanged. The regression coverage enumerates all 1,000 single-digit three-component versions and checks representative non-digit inputs that must retain the existing fallback behavior. ## Performance | Input | Original loop | This PR | Change | | --- | ---: | ---: | ---: | | `1.2.3` | 9.82 ns | 5.03 ns | 1.95× faster | | `1.2` | 7.86 ns | 8.29 ns | 5% slower | | `1.23.4` | 11.59 ns | 11.66 ns | Flat | | `1.2.3rc1` | 8.74 ns | 10.05 ns | 15% slower | The optimized single-digit `x.y.z` shape accounts for 24,000 of 47,641 lockfile version occurrences, or 50.4%. Its improvement should therefore dominate the smaller regressions on fallback inputs. We also tried unrolling the common six-byte shapes (`1.23.4`, `12.3.4`, and `1.2.34`), but the added code size made every measured case slower, so this PR intentionally leaves them on the generic path.
