Move outreach scripts from atleast-leads into this repo

[leogdion]

Summary

Keep lead data private in brightdigit/atleast-leads, but move the remaining scripts into this public site repo so all outreach tooling lives next to the finders.

This is possible without exposing contact details: finders (scripts/find-*.js, verify-leads.js) already live here and write to gitignored leads/. Only drafting tooling is still nested inside the private checkout.

Current split

Location	What
This repo scripts/	find-leads.js, find-studios.js, find-podcasts.js, verify-leads.js, config
Private leads/scripts/	make-drafts.py (used by make drafts), archival _build_outreach_plan_2026_08_24.py
Private leads/ (stay)	reports/, plan/, drafts/, templates/

Proposed work

1. Move make-drafts.py → scripts/make-drafts.py in this repo.
2. Point LEADS_DIR at the sibling leads/ checkout (today the script assumes it lives under leads/scripts/).
3. Update make drafts in the Makefile to call the new path.
4. Update AGENTS/CLAUDE and the private leads/README so atleast-leads is documented as data-only.
5. Remove scripts/ from the private repo (or leave a short pointer) on the next leads snapshot.
6. Decide whether the archival plan builder moves here too or stays in the private repo as history-only.

Leave templates/ in the private repo (outreach copy, not site content).

Out of scope

• Publishing any reports, plan entries, drafts log, or contact details into this repo.
• Changing the leads-clone / leads-pull / leads-backup workflow for the data checkout.
