fix(examples): regenerate stale index.js to unblock the Examples drift check on main

[tonyboylehub]

Why

The Examples drift workflow is failing on main, and every open PR that runs it inherits the failure. It regenerates src/examples/**/index.js with build-examples and fails if the result differs from what is committed.

• main at 9f3535a (feat mpl-core-das updates #542, "feat mpl-core-das updates", merged 2026-09-30 17:45Z): Examples drift failed.
• The previous main run at 8b8c55f (Add tx v1 umi documentation #567): passed.
• Currently blocked by it: docs(genesis): document the Launch Pool soft cap #562, docs(genesis): add refundLaunchPoolV2 and soft cap to the JS SDK reference #563 and fix(docs): resolve every broken in-page anchor link (DEV-173) #572, none of which touch these files. docs(genesis): document the Launch Pool soft cap #562's check job (run 36755897925) fails with src/examples/**/index.js is out of sync with its source files.

The two files that differ are src/examples/core/create-asset/index.js and src/examples/token-metadata/fungibles/create/index.js. Their CLI source files already contain changes that the committed index.js does not reflect.

What

Ran node scripts/build-examples.js on current main and committed the result. Only those two generated files change (2 lines, 1 per file), and both changes are generated output of source already on main:

• core/create-asset: --json becomes --offchain in the files example, and a vanity asset address example is added.
• token-metadata/fungibles/create: adds a vanity mint address example.

No source files and no docs pages are edited.

Why a reviewer is needed

You wrote #542 and the CLI example changes, so you are best placed to confirm two things:

1. That --offchain is the intended flag for mplx core asset create --files, and that the vanity examples (--mint-keypair) should ship. The regenerated output publishes them as they are in the sources.
2. That regenerating, rather than reverting the source changes, is the right fix.

Merging this is also what unblocks the checks on #562, #563 and #572, so a quick review helps those PRs too.

Verification

• After regenerating, git diff shows only the two files above.
• Re-running the build-examples step on this branch produces no further diff, which is what the Examples drift check asserts.
• I did not run pnpm run build; this changes generated example data only.

Summary by CodeRabbit

• New Features
  • Added CLI examples for creating an asset with a vanity address using a supplied mint keypair.
  • Added a fungible-token creation example that uses a supplied keypair to create a vanity mint address.
• Documentation
  • Updated the file-based asset creation example to specify off-chain metadata with --offchain instead of --json.

Walkthrough

The CLI examples add commands that specify mint keypair files for asset and fungible-token creation. The asset example changes its metadata option from --json to --offchain.
