`lucky` should check crystal version in shard.yml before running tasks

Nobody has claimed this yet.

That way it is clear when you have a version mismatch. Should raise if using incorrect version

We'd probably want some kind of `check_crystal_version` around here: https://github.com/luckyframework/lucky_cli/blob/e013182b48a74ac6b609a2daed7ac0156efdaaec/src/lucky.cr#L26

That checks for version mismatch. It should also be disable-able with an ENV var. Like `SKIP_VERSION_CHECK=true lucky my.task`

**It ideally check for a version control software and tell you how to install/switch to a different version.** For example, if `crenv` is installed, show what commands to run. Make it easy

If no crystal version manager software is found, suggest crenv of asdf and point to install page so they can use a version manager

Start at the version-check entry point in src/lucky.cr around line 26 and inspect how the project's shard.yml declares the Crystal version. Define the behavior for mismatches, the SKIP_VERSION_CHECK=true override, and guidance for crenv or asdf; done means the task stops with clear actionable output when the version is wrong and can be explicitly skipped.
