Taras Shynkarenko ccced29b46 perf(build): deduplicate plugin-sdk chunks to fix ~2x memory regression ...

Bundle all plugin-sdk entries in a single tsdown build pass instead of
38 separate builds. The separate builds prevented the bundler from
sharing common chunks, causing massive duplication (e.g. 20 copies of
query-expansion, 14 copies of fetch, 11 copies of logger).

Measured impact:
- dist/ size: 190MB → 64MB (-66%)
- plugin-sdk/ size: 142MB → 16MB (-89%)
- JS files: 1,395 → 789 (-43%)
- 5MB+ files: 27 → 7 (-74%)
- Plugin-SDK heap cost: +1,309MB → +63MB (-95%)
- Total heap (all chunks loaded): 1,926MB → 711MB (-63%)
