## Description The lambda CLI previously only supported inline string expressions and stdin input. This PR adds support for reading lambda expressions from files using the `-f` flag. This makes it easier to work with larger programs stored in files. Changes: - Added `FileSource` type to `internal/config/source.go` for reading from file paths. - Added `-f` flag to CLI argument parser with validation to prevent conflicting inputs. - Updated Makefile targets (`run`, `profile`, `explain`) to use `-f` flag instead of stdin redirection. ### Decisions The `-f` flag takes precedence over positional arguments. If both are specified, an error is returned to avoid ambiguity. ## Benefits - More intuitive workflow for file-based lambda programs. - Cleaner Makefile targets without stdin redirection. - Consistent with common CLI conventions (e.g., `grep -f`, `awk -f`). ## Checklist - [x] Code follows conventional commit format. - [x] Branch follows naming convention (`<type>/<description>`). - [ ] Tests pass (if applicable). - [ ] Documentation updated (if applicable).
