fix: add ajv@^8.20.0 to devDependencies to resolve npm run dev crash

[YASHMAHAKAL]

Problem

npm run dev fails out of the box with:

[webpack-cli] Error: Cannot find module 'ajv/dist/compile/codegen'

Root Cause

Two devDependencies pull conflicting versions of ajv into the tree:

• eslint@10.x requires ajv@^6.x → gets hoisted to top-level node_modules/ajv
• webpack / webpack-dev-server → schema-utils@4.x → ajv-keywords@5.x → peer requires ajv@^8.x

ajv-keywords@5.x is hoisted to the top level and resolves ajv from node_modules/ajv — which is v6. The path ajv/dist/compile/codegen does not exist in v6, causing the crash.

Fix

Add ajv@^8.20.0 to devDependencies. npm hoists v8 to the top level (direct dep wins), ajv-keywords finds v8 there and works. ESLint gets its own nested v6 copy at node_modules/eslint/node_modules/ajv and is unaffected.

ajv is placed in devDependencies and not dependencies because it has no relation to what this library exports — it is purely a dev toolchain version pin. Library consumers should not inherit it.
