Implement the following plan:

# Reorganize reuse into subpackages by concern

Currently all code lives in one flat `reuse` package. Move parsers into public subpackages, matching the `internal/core` + type alias pattern used by manifests and registries.

## Problem: import cycles

Root package (project.go) imports subpackages. Subpackages need `ReuseInfo`, `SourceType`, `PrecedenceType` from root. That's a cycle.

Fix: move shared types to `internal/core`. Root re-exports them as type aliases (`type ReuseInfo = core.ReuseInfo`). Subpackages import `internal/core` directly. No cycles.

## Target structure

```
reuse/
  reuse.go               type aliases from internal/core, package docs
  project.go             Project, OpenProject, ReuseInfoOf, AllReuseInfo
  project_test.go
  covered.go             IsCoveredFile, CoveredFiles, IsIgnoredDir, IsIgnoredFile
  covered_test.go
  internal/
    core/
      core.go            ReuseInfo, SourceType, PrecedenceType (actual definitions + methods)
  extract/
    extract.go           ExtractReuseInfo, ExtractFromFile, FilterIgnoreBlocks
    extract_test.go
  dep5/
    dep5.go              Dep5, ParseDep5, ParseDep5File, ReuseInfoOf
    dep5_test.go
  toml/
    toml.go              ReuseTOML, Annotation, ParseReuseTOML, ParseReuseTOMLFile, ReuseInfoOf
    toml_test.go
    glob.go              GlobMatch (only used by toml, stays here)
    glob_test.go
```

## What moves where

- `reuse.go` types/constants/methods -> `internal/core/core.go`
- `reuse.go` becomes type aliases + package doc
- `extract.go` + test -> `extract/` subpackage, `package extract`, imports `internal/core`
- `dep5.go` + test -> `dep5/` subpackage, `package dep5`, imports `internal/core`
- `toml.go` + test -> `toml/` subpackage, `package toml`, imports `internal/core` and uses alias for BurntSushi/toml (`btoml`)
- `glob.go` + test -> `toml/` subpackage (glob is only used by toml matching)
- `covered.go` + test -> stays in root (no deps on subpackages, no cycle risk)
- `project.go` + test -> stays in root, imports `extract`, `dep5`, `toml` subpackages

## Import paths after reorganization

Consumer usage:
```go
import "github.com/git-pkgs/reuse"           // Project, OpenProject, ReuseInfo, etc.
import "github.com/git-pkgs/reuse/extract"    // ExtractReuseInfo, ExtractFromFile
import "github.com/git-pkgs/reuse/dep5"       // ParseDep5, Dep5
import "github.com/git-pkgs/reuse/toml"       // ParseReuseTOML, ReuseTOML, GlobMatch
```

## Changes to each file

### internal/core/core.go (new)
- All types, constants, methods from current `reuse.go`
- `package core`

### reuse.go (rewrite)
- Package doc stays
- Type aliases: `type ReuseInfo = core.ReuseInfo`, `type SourceType = core.SourceType`, etc.
- Constant re-exports: `const (FileHeader = core.FileHeader; ...)`

### extract/extract.go
- Change `package reuse` -> `package extract`
- Import `github.com/git-pkgs/reuse/internal/core`
- Replace `ReuseInfo` with `core.ReuseInfo`, `FileHeader` with `core.FileHeader`

### dep5/dep5.go
- Change `package reuse` -> `package dep5`
- Import `github.com/git-pkgs/reuse/internal/core`
- Same type replacements

### toml/toml.go
- Change `package reuse` -> `package toml`
- Import `btoml "github.com/BurntSushi/toml"` (alias to avoid name conflict with package name)
- Import `github.com/git-pkgs/reuse/internal/core`
- Same type replacements

### toml/glob.go (moved from root)
- Change `package reuse` -> `package toml`
- No other changes needed

### project.go
- Add imports for `extract`, `dep5`, `toml` subpackages
- Replace direct function calls: `ExtractFromFile` -> `extract.ExtractFromFile`, etc.
- Replace `ParseReuseTOMLFile` -> `toml.ParseReuseTOMLFile`
- Replace `ParseDep5File` -> `dep5.ParseDep5File`
- Types stay as `ReuseInfo` etc. since root re-exports them

### covered.go
- No changes (no deps on moved code, only uses stdlib)

### Tests
- Each test file moves with its source, changes package name
- `assertSlice` helper is duplicated into each test package (or made a shared test helper)
- `mkfile` helper stays in root test (project_test.go, covered_test.go)
- `extract_test.go` and `dep5_test.go` each get their own `assertSlice`

## Verification

1. `go build ./...`
2. `go test -v -race ./...`
3. `go vet ./...`
4. Confirm 64 tests still pass across all packages

### Tool: TaskUpdate

**Args:**

  "taskId": "7"
}
```

## Assistant

**Result** (success):
```
Updated task #7 status
```

## Assistant

Everything is done. Here's a summary of what changed:

**New files:**
- `internal/core/core.go` -- `ReuseInfo`, `SourceType`, `PrecedenceType` and all their constants/methods
- `extract/extract.go` + `extract/extract_test.go` -- SPDX header extraction (was root `extract.go`)
- `dep5/dep5.go` + `dep5/dep5_test.go` -- dep5 parser (was root `dep5.go`)
- `toml/toml.go` + `toml/toml_test.go` -- REUSE.toml parser (was root `toml.go`)
- `toml/glob.go` + `toml/glob_test.go` -- glob matching (was root `glob.go`, moved here since only toml uses it)

**Modified files:**
- `reuse.go` -- rewritten to type aliases and constant re-exports from `internal/core`
- `project.go` -- imports `extract`, `dep5`, `toml` subpackages; `Project` struct fields now use subpackage types
- `covered_test.go` -- added `assertSlice` helper (previously lived in `extract_test.go`)

**Deleted files:**
- `extract.go`, `extract_test.go`, `dep5.go`, `dep5_test.go`, `toml.go`, `toml_test.go`, `glob.go`, `glob_test.go` from root

**Unchanged files:**
- `covered.go`, `project_test.go`

Lint failure: `toml/glob.go:31` wants a tagged switch instead of if/else chain on `next`.

now let's look at the dependabot PRs

```

## Assistant

No open PRs. Dependabot may have auto-merged or the updates were applied directly. Let me check if there are recently closed/merged ones.

## Assistant

### Tool: Bash

**Args:**
```json
{
  "command": "gh pr list --repo git-pkgs/reuse --state all",
  "description": "List all PRs including closed/merged"
}
```

## Assistant

**Result** (success):
```
(empty result)
```

## Assistant

No PRs at all. The Dependabot runs we saw earlier were just the initial config checks, not actual PRs. Nothing to review.

## User

can this tool be used in a similar way to scancode license checker?

## Assistant

## Assistant

They solve related problems but work differently.

ScanCode scans file contents and matches them against a database of known license texts. It can identify a license even when there are no SPDX tags, by recognizing patterns in license headers, notices, and full license texts. It's detection-based.

This library reads structured SPDX metadata that authors have explicitly added following the REUSE spec: `SPDX-License-Identifier` headers, `.license` sidecars, `REUSE.toml` annotations, and `dep5` files. It doesn't try to identify licenses from arbitrary text. If a file has no SPDX tags and isn't covered by a REUSE.toml or dep5 entry, this library just reports it as having no licensing info.

So ScanCode works on projects that haven't adopted any particular standard. This library works on projects that follow the REUSE specification. In a REUSE-compliant project, every covered file has explicit SPDX metadata, and this library is all you need. For projects without that discipline, you'd want something like ScanCode.

They could complement each other: use ScanCode to audit a project that lacks structured metadata, then use the results to add REUSE-compliant tags, then use this library going forward.
