<objective>
Wire all subsystems together through the Cobra CLI: scan command (engine + storage + output), providers list/info/stats commands, and config init/set/get commands. This is the integration layer — all business logic lives in pkg/, cmd/ only wires.

Purpose: Satisfies all Phase 1 CLI requirements and delivers the first working `keyhunter scan` command that completes the end-to-end success criteria.
Output: cmd/{root,scan,providers,config}.go, pkg/config/config.go, pkg/output/table.go.

  <what-built>
Complete Phase 1 implementation:
- Provider registry with 3 YAML definitions, Aho-Corasick automaton, schema validation
- Storage layer with AES-256-GCM encryption, Argon2id key derivation, SQLite WAL mode
- Three-stage scan engine: keyword pre-filter → regex + entropy detector → finding channel
- CLI: keyhunter scan, providers list/info/stats, config init/set/get
  </what-built>
  <how-to-verify>
Run these commands from the project root and confirm each expected output:

1. `cd /home/salva/Documents/apikey && go test ./... -v -count=1`
   Expected: All tests PASS, zero FAIL, zero SKIP (except original stubs now filled)

2. `./keyhunter scan testdata/samples/openai_key.txt`
   Expected: Exit code 1, table printed with 1 row showing "openai" provider, masked key

3. `./keyhunter scan testdata/samples/no_keys.txt`
   Expected: Exit code 0, "No API keys found." printed

4. `./keyhunter providers list`
   Expected: Table with openai, anthropic, huggingface rows

5. `./keyhunter providers info openai`
   Expected: Name, Tier 1, Keywords including "sk-proj-", Pattern regex shown

6. `./keyhunter config init`
   Expected: "Config initialized: ~/.keyhunter.yaml" and the file exists

7. `./keyhunter config set scan.workers 16 && ./keyhunter config get scan.workers`
   Expected: "Set scan.workers = 16" then "16"

8. Build the binary with production flags:
   `CGO_ENABLED=0 go build -ldflags="-s -w" -o keyhunter-prod .`
   Expected: Builds without error, binary produced

- Cobra CLI with scan, providers, config commands (CLI-01)
- `keyhunter config init` creates ~/.keyhunter.yaml (CLI-02)
- `keyhunter config set key value` persists (CLI-03)
- `keyhunter providers list/info/stats` work (CLI-04)
- scan flags: --workers, --verify, --unmask, --output, --exclude (CLI-05)
- All Phase 1 success criteria from ROADMAP.md satisfied:
  1. `keyhunter scan ./somefile` runs three-stage pipeline and returns findings with provider names
  2. Findings persisted to SQLite with AES-256 encrypted key_value
  3. `keyhunter config init` and `config set` work
  4. `keyhunter providers list/info` return provider metadata from YAML
  5. Provider YAML has format_version and last_verified, validated at load time
