feat(feeds): deepen Greek (el) news sources — ERT, AMNA wire, 3 outlets + full server parity

[zionappp-ui]

What this adds

Deepens the Greek (`el`) locale with 5 new sources and fixes a critical server/client parity gap — all 5 existing Greek feeds (Kathimerini, Naftemporiki, in.gr, iefimerida, Proto Thema) were present in `src/config/feeds.ts` but entirely absent from `server/worldmonitor/news/v1/_feeds.ts`. This PR adds them all.

New sources (5 feeds, all verified live)

Source	Type	RSS	Items	Tier
ERT (public broadcaster)	mainstream	Google News el	64	1
AMNA (national wire)	wire	Google News el	100	1
Ta Nea	mainstream	direct	24	2
Liberal GR	mainstream	direct	20	2
CNN Greece	mainstream	direct	22	2

Server parity fix

Kathimerini, Naftemporiki, in.gr, iefimerida, Proto Thema — all added to server digest. Also adds the 3 direct domains (naftemporiki.gr, in.gr, iefimerida.gr) to the vite.config.ts dev-proxy allow-list which was missing them.

ERT (Ellinikí Radiofonía Tileórasi) is Greece's public broadcaster. AMNA (Athens-Macedonian News Agency) is the national wire.

Greptile Summary

This PR deepens Greek (el) news coverage by adding 5 new sources (ERT, AMNA, Ta Nea, Liberal GR, CNN Greece) and fixes a server/client parity gap by backfilling the 5 pre-existing Greek feeds into the server digest. It also promotes several Greek sources in tier rankings and adds the three new direct-RSS domains to the Edge Function allowlist.

• vite.config.ts (broken): Three proxy domains (www.naftemporiki.gr, www.in.gr, www.iefimerida.gr) were accidentally embedded inside BROTLI_EXTENSIONS instead of RSS_PROXY_ALLOWED_DOMAINS, and a missing comma after '.wasm' makes this a hard syntax error — the build will not compile.
• server/worldmonitor/news/v1/_feeds.ts + src/config/feeds.ts: All 10 Greek feeds are correctly wired with the right URLs and language tags.
• Allowlists + tier files: api/_rss-allowed-domains.js, shared/rss-allowed-domains.json, and scripts/shared/… counterparts are consistently updated for the three new direct-RSS domains; source-tiers.json tier promotions look reasonable.

Confidence Score: 2/5

Not safe to merge — vite.config.ts has a syntax error that will break the build on any machine that tries to compile it.

The three Greek proxy domains intended for RSS_PROXY_ALLOWED_DOMAINS were accidentally placed inside BROTLI_EXTENSIONS with a missing comma, producing a TypeScript syntax error that prevents the project from building at all. The rest of the feed additions are correct and well-formed.

vite.config.ts lines 14-17 need the three domain strings removed from BROTLI_EXTENSIONS and added to RSS_PROXY_ALLOWED_DOMAINS instead (around line 583).

Important Files Changed

Filename	Overview
vite.config.ts	Critical syntax error: three proxy domains accidentally injected into BROTLI_EXTENSIONS with a missing comma, breaking the TypeScript build entirely; these were intended for RSS_PROXY_ALLOWED_DOMAINS
server/worldmonitor/news/v1/_feeds.ts	Adds 10 Greek (el) feeds covering server parity (5 existing) and 5 new sources; uses gnLocale helper for Google News feeds and direct RSS URLs for others
src/config/feeds.ts	Adds 5 new Greek feeds (ERT, AMNA, Ta Nea, Liberal GR, CNN Greece) to the client-side feed config
api/_rss-allowed-domains.js	Adds www.tanea.gr, www.liberal.gr, www.cnn.gr to the Vercel Edge Function RSS domain allowlist
shared/rss-allowed-domains.json	Mirrors the api/_rss-allowed-domains.js addition of the three new Greek domains (tanea.gr, liberal.gr, cnn.gr)
scripts/shared/source-tiers.json	Adds 5 new Greek sources with tiers, promotes in.gr/iefimerida/Proto Thema from tier 3 to 2 and Kathimerini from tier 2 to 1; also converts non-ASCII chars to Unicode escapes in several existing entries
shared/source-tiers.json	Identical changes to scripts/shared/source-tiers.json — kept in sync as expected
scripts/shared/rss-allowed-domains.json	Identical to shared/rss-allowed-domains.json update — adds tanea.gr, liberal.gr, cnn.gr

Syntax error: domains injected into wrong Set, missing comma

Three domain strings (www.naftemporiki.gr, www.in.gr, www.iefimerida.gr) were accidentally placed inside BROTLI_EXTENSIONS — a Set of file extensions used for brotli compression — instead of RSS_PROXY_ALLOWED_DOMAINS. Additionally, there is no comma between '.wasm' and 'www.naftemporiki.gr', which is a TypeScript syntax error that will prevent the build from compiling entirely. These domains were intended for RSS_PROXY_ALLOWED_DOMAINS (around line 580), where www.tanea.gr, www.liberal.gr, and www.cnn.gr were correctly added. The fix is to remove these three strings from BROTLI_EXTENSIONS and add them to RSS_PROXY_ALLOWED_DOMAINS instead.
