armistaceandSisyphus f79214bb22 fix: address pr_reviewer findings (data loss, memory, prompt injection) ...

- CI/CD: stop deleting the steward namespace on every deploy; use
  kubectl apply (dry-run -> apply) so the PVC and conversation memory
  survive deployments.
- core: bound _histories with an LRU eviction (max 1000 active threads)
  to prevent unbounded memory growth.
- core: wrap knowledge-base context in KB START/END delimiters and
  instruct the LLM to treat it as data, mitigating indirect prompt
  injection.
- matrix: wrap message processing in try/except so failures are logged
  instead of silently dropped.
- telegram: remove now-dead flush/tags prompt constants (centralized in
  core).
