VAI-179: Migrate from pegjs/phpegjs to peggy/phpeggy

- Replace deprecated pegjs/phpegjs with peggy@^3.0.2 + phpeggy@^2.0.1
- Remove standalone [email protected] (was shadowing typescript's tsc binary)
- Update Makefile: node:8 -> node:20-alpine, npx pegjs -> npx peggy,
  phpegjs option key -> phpeggy
- Update grammar: wrap PHP initializer closures in initialize() method
  (phpeggy 2.x places initializer at class body level, not inside parse())
- Add explicit private \Closure declarations to prevent PHP 8.2+ dynamic
  property warnings
- Fix $_location closure: use ->line/->column (pegCachedPosDetails object)
  instead of ['line']/['column'] (array) — phpeggy 2.x breaking change
- Fix Function rule: * -> + to reject empty function name @()
- Regenerate dist/BaseExpressionParser.php, dist/Parser.js, dist/Parser.d.ts
  and dist/Parser.js.map with new toolchain
