Support Bun 1.4 pacakge manager commands

[jong-kyung]

Bun 1.4 adds support for several package manager commands that were previously unavailable:

• bun dedupe
• bun prune
• bun audit fix

We should update the Bun package manager integration to support these commands.

Related Bun issues:

• bun dedupe: Deduplicate / dedupe command for bun install oven-sh/bun#1343
• bun prune: Support bun prune in package manager oven-sh/bun#3605
• bun audit fix: Implement bun audit fix with targeted dependency fixes. oven-sh/bun#20238

They were implemented together in:
oven-sh/bun#38333
