fix(hg): show clone errors, stable cwd; shrink timeline fonts

Remove /dev/null redirects in hg-ingest.sh so errors are visible.
cd to work dir before loop to prevent getcwd failures after rm.
Use $HOME instead of ~ for proper expansion in default values.

Reduce timeline entry title, subtitle, and body font sizes for a
more compact activity feed.
