add arcodange-email-ingest — Zoho Mail → Dolibarr supplier-invoice drafts

Browse Source 
V8 — first inbound-side skill. Closes the loop from "bill arrives by email"
to "ready to enter in Dolibarr UI". Read-only at every layer.

What ships:
- arcodange-email-ingest/scripts/zoho-curl.sh   OAuth wrapper with token cache
                                                (50 min TTL, mode 600) — avoids
                                                hitting Zoho OAuth rate limit on
                                                every invocation.
- arcodange-email-ingest/scripts/email-list.sh   List candidates in /Inbox/books
                                                (where the books@ alias auto-
                                                routes mail). --candidates-only
                                                filter on supplier patterns or
                                                attachments. --all-folders to
                                                scan everything.
- arcodange-email-ingest/scripts/email-inspect.sh   Pull message + attachments,
                                                pdftotext on each PDF, heuristic
                                                extract (supplier, ref, dates,
                                                totals, VAT rate), emit Dolibarr
                                                supplier-invoice draft JSON.

Architecture choice — Zoho API (not IMAP):
- books@arcodange.fr is an alias of gabrielradureau@arcodange.fr → one OAuth
  refresh_token covers everything.
- Gmail folded in via forwarding (arcodange@gmail.com → books@) — no Google
  API setup, no app-passwords, no second OAuth flow.
- Token-based auth, no SCA rabbit hole.

V8.0 baseline (in /Inbox/books):
- 3 candidates: Mistral AI facture, Anthropic Stripe receipt (Fwd Gmail),
  INPI payment receipt (Fwd Gmail).
- Heuristic extraction is best-effort: works on amounts/refs for some
  templates, misses others (Mistral PDF format, Stripe receipt layout).
- --save-pdf <DIR> lets the operator grab the PDFs for manual entry when
  the heuristic falls short.

Rate-limit pitfall documented: Zoho OAuth refresh has an aggressive throttle
("too many requests continuously"). The cache file at $TMPDIR/zoho-access-$USER
(mode 600, 50 min TTL) prevents this; on 401 the wrapper auto-refreshes once
and retries.

V8.1+ ideas in SKILL.md out-of-scope:
- mark ingested emails (IMAP flag or Zoho label)
- body text extraction (inline-HTML invoices)
- per-template parsers or LLM-based extraction
- IMAP fallback for non-Zoho mailboxes

CLI: bin/arcodange email {list|inspect|curl} integrated.
Base updates: dolibarr/SKILL.md cross-link, dolibarr/README.md env schema
extended with ZOHO_CLIENT_ID/SECRET/REFRESH_TOKEN/DC.
