Anchor page-run selection to start at page 1 (select_continuous_run_from_page_1) instead of picking the longest run, so newest pages are preserved and the newest timestamp ordinal 0 is always captured. Change boundary logic to always assign stable UIDs and export the captured prefix of an oldest timestamp group even when it may be an unfinished 10-pull, emitting informational warnings (INCOMPLETE_TIMESTAMP_GROUP_EXPORTED / INCOMPLETE_ARC_10_PULL_EXPORTED) instead of dropping rows. Apply the same policy to Arc groups and update arc group annotation and warnings accordingly. Add a new console module for improved CLI output and update cli, live_capture, adapters, and session code to use the new run selection and console helpers. Update docs, mappings, and tests to reflect the new boundary/export behavior and messaging.
