[BUG] Claude compilation omits CLAUDE.md from three-level dependencies

Describe the bug

apm compile --target claude does not import dependency CLAUDE.md files when the dependency is materialized more than two directory levels below apm_modules.

Azure DevOps dependencies use paths such as apm_modules/<org>/<project>/<repo>, but Claude compilation only checks apm_modules/<owner>/<package>/CLAUDE.md.

To Reproduce

Steps to reproduce the behavior:

1. Install an Azure DevOps dependency that contains a root CLAUDE.md.
2. Confirm the dependency is materialized at apm_modules/org/project/repo/CLAUDE.md.
3. Run apm compile --target claude.
4. Inspect the generated root CLAUDE.md.
5. Observe that it does not contain @apm_modules/org/project/repo/CLAUDE.md.

A minimal filesystem probe containing both two-level and three-level dependencies returns only:

['@apm_modules/owner/package/CLAUDE.md']

Expected behavior

The generated root CLAUDE.md should include an import for every installed dependency containing a root CLAUDE.md, including:

@apm_modules/org/project/repo/CLAUDE.md

Environment (please complete the following information):

• OS: Windows
• Python Version: 3.12.13
• APM Version: 0.30.0

Logs

No error is reported. The dependency import is silently omitted from the generated root CLAUDE.md.

Additional context

src/apm_cli/compilation/claude_formatter.py method _collect_dependencies scans exactly two directory levels below apm_modules and checks only <owner>/<package>/CLAUDE.md.

src/apm_cli/models/dependency/materialization.py materializes Azure DevOps dependencies at <org>/<project>/<repo> and supports deeper repository paths for other hosts.

Dependency imports should be derived from installed package roots or lockfile/materialization records instead of assuming exactly two path components.

Start in src/apm_cli/compilation/claude_formatter.py at _collect_dependencies and compare its two-level scan with the paths produced by src/apm_cli/models/dependency/materialization.py. Reproduce with two-level and three-level installed dependencies, then run the relevant compilation tests or probe. Done means the generated root CLAUDE.md imports every installed dependency root that contains CLAUDE.md, including @apm_modules/org/project/repo/CLAUDE.md.
