This PR:

• Reorganizes bolt-cli templates in separated files
• Starts using bolt.workspace in the generated projects to make it easier to change used bolt version
• Gets rid of warnings messages about missing features by adding anchor-debug, custom-heap and custom-panic to generated Cargo.toml files

Status	Type	⚠️ Core Change	Issue
Ready	Refactor	No	No issue

Problem

• Whole templates are inlined and they make the source code files too big and hard to read
• Setting up a generated bolt project to use a patched version requires changing all the Cargo subprojects
• Too much warning messages

Solution

• Create separate template files
• Use workspace version
• Clean them :)
