refactor: major update on command order and pkg. -pre-release

[adharshmk96]

currently stk binary is split to

• migrator
• project

stk binary should do initialization on init command

eg usage:

stk init - generates project and config ( from template ) stk add module ,, - generates modules stk verify - verifies stk config

stk migrator init - initialize migrator config ( use .stk.yaml ) stk migrator generate -n stk migrator clean stk migrator purge stk migrator up stk migrator down stk migrator verify

after this update, the release should be 1.0.0-alpha.1

Update: rewriting the project package, partially implemented generator, unable to push due to unit test fail related to go mod tidy.

update: refactoring side effects to be grouped as reciever methods and exported as interface.
