perf: skip extension hooks when schema has no extensions

resolvePlannedField unconditionally called handleExtensionsResolveFieldDidStart,
which allocates a map[string]ResolveFieldFinishFunc + a closure on
every resolved field — even when the schema has zero extensions
registered. With ~1000 fields per request that's 2000 wasted allocs
per request on the common no-extensions case.

Gate the call (and the matching finish-handler invocation) behind
`len(eCtx.Schema.extensions) > 0`.

Wide-query bench (100 fields × 10 items):
  before: 1.15ms / 9043 allocs/op
  after:  0.99ms / 7040 allocs/op   (-14% time, -22% allocs)

Hot-loop with native variables:
  before: 1.44ms / 9888 allocs/op
  after:  1.30ms / 7884 allocs/op   (-10% time, -20% allocs)

Schemas with extensions registered take the same path as before.
