release: fix version ldflags package path

[yaoge123]

Summary

The .goreleaser.yml ldflags line targets github.com/ustclug/rsync-proxy/pkg/info.{Version,BuildDate,GitCommit}, but no such package exists. The actual variables live in the cmd package (cmd/cmd.go):

var (
    Version   = "0.0.0"
    GitCommit = "$Format:%H$"
    BuildDate = "1970-01-01T00:00:00Z"
)

Go's linker silently ignores -X for unresolved symbols, so the released binary keeps the source defaults.

Reproduction

The v0.1.4 release binary:

$ rsync-proxy_linux_amd64 version
{"GitCommit":"$Format:%H$","BuildDate":"1970-01-01T00:00:00Z","Version":"0.0.0",...}

Fix

Update the package path in .goreleaser.yml to match the variable locations and the existing Makefile (which uses github.com/ustclug/rsync-proxy/cmd.Version).

Verification

Local build with the corrected ldflags reports the injected values correctly.

Pull request overview

Note

Copilot was unable to run its full agentic suite in this review.

Updates the ldflags path in the GoReleaser config to point to the new location of the version variables (cmd package instead of pkg/info).

Changes:

• Updates -X ldflag paths from pkg/info to cmd package for Version, BuildDate, and GitCommit variables.

Added regression tests in 49139e5:

• cmd/cmd_test.go: drives printVersion directly with overridden package vars to confirm Version/GitCommit/BuildDate flow through to the JSON output, and that --pretty indents.
• test/release/version_test.go: builds the root package with the same -X package path declared in .goreleaser.yml and execs rsync-proxy version from the resulting binary. The path lives in a single constant so the test and the goreleaser config cannot silently drift.

Verified by temporarily flipping the constant to the old pkg/info path: the release test fails with messages explicitly pointing at .goreleaser.yml. Restoring the correct cmd path makes both packages green.

这里的测试我感觉是没有必要的？

那就简单点只改 .goreleaser.yml
