fix(platform-api-docs): prefer source over build output when deduplicating

[cryptodev-2s]

Explanation

A capability declared in a package's source is also visible in the dist built from it, and a cross-package import resolves to that dist rather than to the sibling's source. Whichever was reached first won, so 83 of 1164 source links pointed at .d.cts build output instead of code you can read and edit.

Deduplication now scores source above build output, so the outcome no longer depends on traversal order. All 1164 links point at source, and namespace, action and event counts are unchanged.

Both clients generate byte-identical docs, since they only ever see published packages and score every candidate the same way.
