…r validation (#17)

## Problem

The GoReleaser step in the CD workflow was failing with the error:
```
git tag v0.2.0 was not made against commit 46a7854
```

## Root Cause Analysis

The workflow was overriding `GORELEASER_CURRENT_TAG` with just the
semantic version (`v0.2.0`), but the actual git tag created by
release-please uses the full monorepo format
(`protoc-gen-elixir-grpc@v0.2.0`).

When tested locally:
- **Setting `GORELEASER_CURRENT_TAG=v0.2.0`** → `git tag v0.2.0 was not
made against commit...` ❌
- **Setting `GORELEASER_CURRENT_TAG=protoc-gen-elixir-grpc@v0.2.0`** →
`failed to parse tag as semver: invalid semantic version` ❌
- **Removing `GORELEASER_CURRENT_TAG` entirely** → GoReleaser
auto-detects the full tag correctly, but semver validation fails ⚠️

## Solution

1. **Remove `GORELEASER_CURRENT_TAG`** - Let GoReleaser auto-detect the
tag from git (it correctly finds `protoc-gen-elixir-grpc@v0.2.0`)
2. **Add `--skip=validate` flag** - Bypass semver validation since our
tags use `component@version` format

## Local Validation

Dry-run test confirmed the fix works:
```bash
BUILD_COMPONENT="protoc-gen-elixir-grpc" goreleaser release --clean --skip=publish,validate
```

Results:
- ✅ Auto-detected tag: `protoc-gen-elixir-grpc@v0.2.0`
- ✅ Built all 6 binaries successfully (darwin/linux/windows,
amd64/arm64)
- ✅ Generated correct build artifacts with version
`protoc-gen-elixir-grpc@v0.2.0`

## Impact

This fix enables the release workflow to properly handle monorepo tags
for both:
- `protoc-gen-elixir-grpc`
- `protoc-gen-connect-go-servicestruct`

## Problem

Archive names are unnecessarily long and duplicate the component name:
```
protoc-gen-elixir-grpc_protoc-gen-elixir-grpc@v0.2.0_Darwin_arm64.tar.gz
                      ^^^^^^^^^^^^^^^^^^^^^^^^
                      duplicated!
```

## Root Cause

The GoReleaser archive template was using:
```yaml
{{ .Env.BUILD_COMPONENT }}_{{- .Version }}_...
```

Where:
- `BUILD_COMPONENT` = `protoc-gen-elixir-grpc`
- `.Version` = `protoc-gen-elixir-grpc@v0.2.0` (full monorepo tag)

This resulted in the component name appearing twice.

## Solution

Remove the `{{ .Env.BUILD_COMPONENT }}` prefix from the archive template
since `.Version` already contains the full monorepo tag format.

## Result

Cleaner archive names:
```
protoc-gen-elixir-grpc@v0.2.0_Darwin_arm64.tar.gz
protoc-gen-elixir-grpc@v0.2.0_Linux_x86_64.tar.gz
protoc-gen-elixir-grpc@v0.2.0_Windows_x86_64.tar.gz
```

## Testing

Validated locally with:
```bash
BUILD_COMPONENT="protoc-gen-elixir-grpc" goreleaser release --snapshot --skip=validate
```
