generate Mintlify docs for hashnode

[ambikeesshh]

Problem

packages/hashnode is on main, but there is no docs/plugins/hashnode page and it is missing from the Mintlify nav.

Fix

Generate the plugin docs and let the script update the sidebar:

pnpm generate:docs -- --plugin=hashnode

Commit the generated MDX under docs/plugins/hashnode/ plus any docs/docs.json nav change.

Touch

• docs/plugins/hashnode/ (generated)
• docs/docs.json (nav entry, if the script updates it)

Done when

• docs/plugins/hashnode/ exists with the usual pages
• hashnode shows up under Plugins in docs/docs.json
• no hand-written one-off layout that ignores the generator

Verify

ls docs/plugins/hashnode
rg 'hashnode' docs/docs.json

closing. hashnode docs already on main
