fix: remove duplicate russia-rosstat and indonesia-bps files

[mingcha-dev]

PR #78 added russia-rosstat and indonesia-bps in countries/ paths, but they already existed in russia/national/ and indonesia/national/.

This removes the old files (less complete) and keeps the newer countries/ versions.

• Delete russia/national/russia-rosstat.json (keep countries/europe/russia/russia-rosstat.json)
• Delete indonesia/national/indonesia-bps.json (keep countries/southeast-asia/indonesia/indonesia-bps.json)

✅ LGTM. 删除旧路径的重复文件，保留 countries/ 下的新版本。建议尽快合并。

Confirmed: only deletes old-path duplicates. LGTM ✅

⚠️ Critical: Index files not updated

This PR deletes two source files, but all 4 index files still reference the old paths:

Index File	Old path references (will become dangling)
all-sources.json	indonesia/national/indonesia-bps.json, russia/national/russia-rosstat.json
by-authority.json	same
by-domain.json	same (multiple entries each)
by-region.json	same

Meanwhile, the new countries/ paths (countries/asia/indonesia/indonesia-bps.json, countries/europe/russia/russia-rosstat.json) are not present in any index file.

After merge, the indexes would have broken references to deleted files, and the kept countries/ versions would be invisible to search.

Action needed: Update the index files to replace old paths with new countries/ paths, or regenerate the indexes.

✅ Duplicate check passed

• Confirmed countries/ versions exist and are more comprehensive (richer descriptions, more domains/tags, detailed data_content).
• IDs match (russia-rosstat, indonesia-bps) — no ID duplication after merge.

✅ Schema & format check passed

• No underscores in domains ✓
• All URLs use https ✓
• Both kept files have valid JSON structure ✓

ℹ️ URL reachability (informational)

• bps.go.id — 403 (WAF/anti-bot, expected for gov sites)
• rosstat.gov.ru — timeout (likely geo-restricted outside Russia)

These are typical for government statistical sites and not a blocker.

Summary: Please update the index files before merge. The source file cleanup itself is correct.
