<objective>
Initialize the Go module, install all Phase 1 dependencies at pinned versions, create the minimal main.go entry point, and lay down test scaffolding with testdata fixtures that every subsequent plan's tests depend on.

Purpose: All subsequent plans require a compiling module and test infrastructure to exist before they can add production code and make tests green. Wave 0 satisfies this bootstrap requirement.
Output: go.mod, go.sum, main.go, pkg/*/test stubs, testdata/ fixtures.

```bash
go mod init github.com/salvacybersec/keyhunter

go get github.com/spf13/viper@v1.21.0
go get modernc.org/sqlite@latest

go mod tidy

Verify the resulting go.mod contains:

Create the following files:

**main.go** (must be under 30 lines):
```go
package main

import "github.com/salvacybersec/keyhunter/cmd"

func main() {
    cmd.Execute()
}
```

**testdata/samples/openai_key.txt** — file containing a synthetic (non-real) OpenAI-style key for scanner integration tests:
```
# Test file: synthetic OpenAI key pattern
OPENAI_API_KEY=sk-proj-ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqr1234
```

**testdata/samples/anthropic_key.txt** — file containing a synthetic Anthropic-style key:
```
# Test file: synthetic Anthropic key pattern
export ANTHROPIC_API_KEY="sk-ant-api03-ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxy01234567890-ABCDE"
```

**testdata/samples/multiple_keys.txt** — file with both key types:
```
# Multiple providers in one file
OPENAI_API_KEY=sk-proj-ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqr5678
ANTHROPIC_API_KEY=sk-ant-api03-XYZabcdefghijklmnopqrstuvwxyz01234567890ABCDEFGH-XYZAB
```

**testdata/samples/no_keys.txt** — file with no keys (negative test case):
```
# This file contains no API keys
# Used to verify false-positive rate is zero for clean files
Hello world
```

**pkg/providers/registry_test.go** — test stubs (will be filled by Plan 02):
```go
package providers_test

import (
    "testing"
)

// TestRegistryLoad verifies that provider YAML files are loaded from embed.FS.
// Stub: will be implemented when registry.go exists (Plan 02).
func TestRegistryLoad(t *testing.T) {
    t.Skip("stub — implement after registry.go exists")
}

// TestProviderSchemaValidation verifies format_version and last_verified are required.
// Stub: will be implemented when schema.go validation exists (Plan 02).
func TestProviderSchemaValidation(t *testing.T) {
    t.Skip("stub — implement after schema.go validation exists")
}

// TestAhoCorasickBuild verifies Aho-Corasick automaton builds from provider keywords.
// Stub: will be implemented when registry builds automaton (Plan 02).
func TestAhoCorasickBuild(t *testing.T) {
    t.Skip("stub — implement after registry AC build exists")
}
```

**pkg/storage/db_test.go** — test stubs (will be filled by Plan 03):
```go
package storage_test

import (
    "testing"
)

// TestDBOpen verifies SQLite database opens and creates schema.
// Stub: will be implemented when db.go exists (Plan 03).
func TestDBOpen(t *testing.T) {
    t.Skip("stub — implement after db.go exists")
}

// TestEncryptDecryptRoundtrip verifies AES-256-GCM encrypt/decrypt roundtrip.
// Stub: will be implemented when encrypt.go exists (Plan 03).
func TestEncryptDecryptRoundtrip(t *testing.T) {
    t.Skip("stub — implement after encrypt.go exists")
}

// TestArgon2KeyDerivation verifies Argon2id produces 32-byte key deterministically.
// Stub: will be implemented when crypto.go exists (Plan 03).
func TestArgon2KeyDerivation(t *testing.T) {
    t.Skip("stub — implement after crypto.go exists")
}
```

**pkg/engine/scanner_test.go** — test stubs (will be filled by Plan 04):
```go
package engine_test

import (
    "testing"
)

// TestShannonEntropy verifies the entropy function returns expected values.
// Stub: will be implemented when entropy.go exists (Plan 04).
func TestShannonEntropy(t *testing.T) {
    t.Skip("stub — implement after entropy.go exists")
}

// TestKeywordPreFilter verifies Aho-Corasick pre-filter rejects files without keywords.
// Stub: will be implemented when filter.go exists (Plan 04).
func TestKeywordPreFilter(t *testing.T) {
    t.Skip("stub — implement after filter.go exists")
}

// TestScannerPipeline verifies end-to-end scan of testdata returns expected findings.
// Stub: will be implemented when engine.go exists (Plan 04).
func TestScannerPipeline(t *testing.T) {
    t.Skip("stub — implement after engine.go exists")
}
```

Create the `cmd/` package directory with a minimal stub so main.go compiles:

**cmd/root.go** (minimal stub — will be replaced by Plan 05):
```go
package cmd

import "os"

// Execute is a stub. The real command tree is built in Plan 05.
func Execute() {
    _ = os.Args
}
```

After creating all files, run `go build ./...` to confirm the module compiles.
