feat(telemetry): add developer messages to tool error spans (#831)
## Summary
- Add shared span attributes for tool error diagnostics, including
developer-facing messages when present.
- Wire those attributes through MCP server, worker RunTool, and HTTP
CallTool spans while keeping default MCP response content public-only.
- Cover no-leak response behavior, non-recording spans, outputless
worker responses, and the shared attribute contract.

## Verification
- `uv run ruff format ...`
- `uv run ruff check ...`
- `uv run pytest -W ignore
libs/tests/arcade_mcp_server/test_debug_exposure_integration.py
libs/tests/core/test_log_extras.py
libs/tests/worker/test_worker_base.py`

> [!NOTE]
> **Medium Risk**
> Adds new telemetry attributes that propagate tool error messages
(including optional developer_message) into active spans across MCP
server and worker execution paths; risk is mainly around potential
leakage of sensitive developer messages into tracing backends and
changes to observability contracts.
> 
> **Overview**
> Adds a shared
`arcade_core.log_extras.build_tool_error_span_attributes()` helper and
wires it into tool error paths so the current OpenTelemetry span is
annotated with stable `tool_error_*` attributes (including
`developer_message` when present).
> 
> MCP tool calls now record these span attributes on failure while
keeping default MCP response content sanitized, and `arcade-serve`
records the same attributes on both `RunTool` and HTTP `CallTool` spans
(handling `output=None`). Versions and dependency constraints are bumped
to consume the new core helper, with tests added/updated to lock the
span-attribute contract and verify behavior for non-recording spans and
no-leak responses.
