Add 2 new CfP/edition entries (cfp-scout 2026-08-29)

[JesperDramsch]

Scouted 10 stale conference series (rotation index 75, wrapping) for new editions and CfPs. Both new findings turned out to be editions that already took place earlier in 2026 (their dates are in the past relative to today, 2026-08-29), so sort_yaml.py correctly filed them straight into _data/archive.yml rather than the active list — they're added for record completeness.

Series	Year	CfP deadline	Evidence URL
PyDay Valparaiso	2026	TBA (CfP closed by the time of this scout; no exact deadline published on the page)	https://www.pyday.cl/valparaiso/
Wagtail Space Netherlands	2026	2026-05-29 23:59	https://nl.wagtail.space/call-for-participation

Other series checked (no entry added)

Series	Classification	Notes
PyDay Copiapó	NO_NEWS	/copiapo.html 404s; the parent site's 2026 listing (Valparaíso, Santiago, Rancagua) does not include Copiapó — likely dropped from this year's rotation.
Python Niger	DEAD_SITE	The tracked link was already an archived (web.archive.org) Facebook event page; no live site or newer info found via search. Legacy suspect.
Python Pizza Prague	NO_NEWS	Site still only shows the 2024 event; no 2026 edition or CfP announced.
Python fwdays	NO_NEWS	fwdays.com's 2026 events list has no Python/Data-Science-specific conference; only unrelated tracks (AI agents, Kubernetes, DevOps, etc.) and a generic "Fwdays Tech Summit" that isn't confirmed as the Python series.
Python in Education Day	DEAD_SITE	scienceoxford.com/python-in-education-day/ 404s and the event is absent from the Science Oxford homepage. Legacy suspect.
Wagtail Space US	NO_NEWS	Site still shows the 2024 edition (Philadelphia); CfP closed, no 2026 edition announced.
DjangoCon Europe	NO_NEWS	Already fully recorded in _data/archive.yml (2026, Athens, Apr 15–19) from a prior scout run — not a new finding.
FOSDEM	NO_NEWS	Already recorded in _data/archive.yml (2026, Brussels, Jan 31 – Feb 1) from a prior scout run — not a new finding.

Ran python utils/sort_yaml.py --skip_links after appending entries; validation passed clean, only _data/conferences.yml and _data/archive.yml changed, and no new duplicate series+year pairs were introduced (pre-existing PyCon China/RuPy duplicates are unrelated to this change).
