feat: define Function and Trigger CRD types

Function:
  - runtime (go1.21/python3.11/nodejs20)
  - entrypoint, s3Bucket, s3Key
  - memoryMB (default 128), timeoutSec (default 30)
  - env map
  - status: phase (Pending/Building/Ready/Failed), imageRef, conditions

Trigger:
  - type (http/cron), functionRef
  - schedule (cron only)
  - preWarmSeconds (default 300) - pre-warm before cron run
  - status: active, url, lastScheduleTime
