Reviewer feedback on the previous commit flagged two real problems:
1. Overloading --yes to also auto-mine was a silent behaviour change for
scripted callers. Today --yes only auto-accepts entities — making it
ALSO trigger a multi-minute ChromaDB write breaks every script that
currently runs `mempalace init --yes <dir>` for the fast non-interactive
entity path. Add a separate `--auto-mine` flag instead. Combinations:
mempalace init --yes <dir> # entities auto, STILL prompt mine
mempalace init --auto-mine <dir> # prompt entities, skip mine prompt
mempalace init --yes --auto-mine <dir> # fully non-interactive
--yes behaviour is now identical to pre-PR.
2. The mine prompt was firing without telling the user how big the job
was. On a real corpus mine takes minutes-to-tens-of-minutes; hitting
Enter on default-Y with no size cue is a footgun. Show a one-line
estimate computed from scan_project (the same walk we hand into mine)
BEFORE the prompt:
~423 files (~12 MB) would be mined into this palace.
Mine this directory now? [Y/n]
The estimate uses a single corpus walk: scan_project's output is
passed into mine() via a new optional files= kwarg, so we never walk
the tree twice.
Tests: replaced the old "--yes auto-mines" assertion with a regression
guard that --yes alone STILL prompts; added coverage for --auto-mine
alone, --yes --auto-mine together, and the pre-prompt estimate line.
