dqcheckrGUI 0.1.0

• Initial release: a point-and-click ‘shiny’ front-end for ‘dqcheckr’ that drives automated dataset quality checks without writing any R code.
• Configuration wizard for setting up checks on a new dataset (identity, files, structure, columns, rules, overrides, custom checks, review/save), a run panel for launching checks against incoming file deliveries and viewing the generated HTML report, and a history browser for past results and drift comparisons between snapshots.
• CSV onboarding handles header rows with duplicate or otherwise invalid column names (e.g. an extract that repeats PayeeName/Amount): a raw-header probe (name_repair = "minimal") recovers the names and suggest_col_names() proposes valid, unique, editable fixes. On save a renamed header is written as col_names plus csv_skip: 1, so ‘dqcheckr’ (>= 0.2.2) skips the original header row instead of reading it as data; clean files write neither key.
• Relative snapshot_db / report_output_dir paths in the config are resolved against the deployment root (the parent of the config directory), and background callr runs execute with wd set there, so the GUI reads and writes the same snapshot database the ‘dqcheckr’ CLI does. Absolute paths continue to work unchanged.
