Implement new identifier keys for file names

Summary:
Adopt a hybrid approach (Slugify + Short Hash) to generate safe, human-readable, and unique filenames across different filesystems.

---

Context

There are blockers when mapping identifiers directly to the file system:

• Identifiers are case-sensitive.
• Most operating systems are not case-sensitive, which can cause conflicts.

To address this, the most acceptable option is a hybrid approach using slugify and hash startegy.

---

Hybrid: Slugify + Short Hash

What it does:

• Slugify for readability.
• Append a short hash of the original identifier for uniqueness.

Example mapping:

• My:Component → my_component_a12f4c.toml
• My/Component → my_component_b91d0e.toml

Pros:

• Human-readable (my_component part).
• Collision-resistant (hash ensures uniqueness).
• Works across case-insensitive and case-sensitive filesystems.

Cons:

• Slightly longer filenames.
