fix: correct MCP SSE launch, shebang ordering, and E2E helper scripts

- execution_mixin: replace non-existent FastMCP.create_app() with the
  repo's working low-level SSE transport pattern (connect_sse +
  handle_post_message), matching mcp/mcp_server.py; normalize base_path
  leading slash. Fixes AttributeError at MCP server startup.
- examples (36 files): move '# praisonai: skip=true' below the shebang so
  direct execution still works; directive stays within the runner's
  first-30-lines scan.
- failover_example: display real 'last_error' instead of unmodeled
  'failure_count' (which always printed 0).
- scripts/apply_e2e_batch3_*.py: make skip insertion shebang-aware, wire
  the previously-uncalled fix_mcp_env_examples(), and make the E2E report
  path a CLI argument (defaulting to the audit path).

-"""Prompt-cache-stability contract for the Agent turn (Issue #3352).

-conversation the cached prefix — the system instructions, the serialised tool
-schemas, and the model identity — is the dominant cost and latency lever.
-
-Gateways run many users on a single shared ``Agent`` instance and swap
-``tools``/``llm`` in and out per turn (per-route tool scoping, per-user
-``/model`` override). Those swaps silently change the cached prefix and the
-provider cache misses with zero operator visibility.
-
-``prompt_prefix_signature`` gives callers a single, cheap, deterministic
-fingerprint of exactly the cache-relevant inputs — model, the sorted set of
-tool names, and a fingerprint of the system instructions — and *nothing*
-volatile per-turn (arrival time, routing facts, memory/RAG recall). When the
