**Problem:**
- HTab/VTab components received onclick as a parameter
- When binding events, codegen used parameter name "onclick" instead of actual function
- Runtime couldn't find handler function in WASM exports
**Root Cause:**
We don't support passing functions as component parameters yet. When a child
component uses onclick=onclick where onclick is a parameter, we bind the
string "onclick" instead of tracking which function was actually passed.
**Fix:**
Inlined HTab and VTab components back into parent components. Now lambdas
are directly on Button elements, so they generate proper synthetic handlers
(_lambda_0_Tabs, _lambda_1_Tabs, etc.) that get exported.
**Result:**
✅ All tab click handlers now work
✅ Handlers exported: _lambda_0_Tabs, _lambda_1_Tabs, _lambda_2_Tabs,
_lambda_0_VerticalTabs, _lambda_1_VerticalTabs, _lambda_2_VerticalTabs
**TODO:**
Implement function pointers/delegates as component parameters to restore
component reusability (tracked in TYPE_SYSTEM_ROADMAP.md)
