Auto-generate Stellar contract reference from contract source

[heymide]

Close: #25
Changed:
Added package.json with scripts for:npm run generate:stellar-reference
npm run check:stellar-reference
Mintlify validate/link checks

Added generated-reference markers to contracts/stellar.mdx.
Tightened scripts/generate-stellar-reference.ts so it:runs cleanly as ESM under Node 24
skips check mode gracefully when bindings are absent
handles BOM-prefixed JSON files
parses multi-field event types correctly

Verified:
npm run check:stellar-reference passes in this checkout by skipping because no Stellar bindings/config are present.
Ran an end-to-end temporary fixture with fake bindings; generation and --check both passed.

Heads up: I retargeted this from main to develop. For wave 6 all PRs land on develop first (we freeze on develop before merging to main). No action needed from you, just a heads-up. If you rebase in the future, base on origin/develop, not origin/main.

Oh, Okay
I'll keep that in mind

Now conflicts in package.json because #47 just landed and added validator deps. Quick rebase:

git fetch origin
git rebase origin/develop
# in package.json, keep both sets of additions
git push --force-with-lease

The auto-gen script and contracts/stellar.mdx update land clean.
