Kept new Dagger functions (FormatWrite, Analyze, Codegen, AnalyzeFix, CheckFast) from
issue-417 branch and updated CheckFast to call CheckGenerated (renamed on main from CheckMocks).

Adds CheckFast, Analyze, FormatWrite, Codegen, and AnalyzeFix Dagger
functions to ci/main.go. Updates format, codegen, analyze, analyze-fix,
and check-fast Taskfile tasks to run via Dagger and export changed files
back to the host with -o .. Updates the dart-check pre-commit hook to
call check-fast through Dagger instead of scripts/pre_commit_check.sh.
Closes#417
