fix(instrumentation-py): repair Strands Agents, Superagent, and Temporal OTel 2.x spans

[Nightingalelyy]

Summary

• Repair the Python Strands Agents, Superagent, and Temporal instrumentations for current OTel 2.x and current supported SDKs.
• Normalize canonical agent, task, chat, tool, guardrail, workflow, and Temporal runtime spans while preserving contract-correct ownership of model, usage, tool, and failure fields.
• Add bounded privacy-safe serialization, shared/ref-counted lifecycle handling, current SDK dependency floors, and a patch release intent for all three packages.

Validation

• Focused package tests pass: Strands Agents 13/13, Superagent 16/16, and Temporal 14/14 (43/43 total), including declared-minimum SDK environments.
• Root-scoped Ruff check and format check pass for every changed package source and test file.
• All three wheels build and pass isolated installation, import, entry-point, and pip check validation.
• Release inventory, release-intent, missing-intent, and git diff --check validations pass.
• The full respan/contribution/ contract was re-read and the final source/example diffs were audited against it.
• All 13 paired example processes completed under exact marker otel2-fix-py-group-26-20260818T090100Z.
• Respan MCP audit opened all 13 trees and all 53 full records: one root per trace, exact parentage, unique log/span IDs, exact markers, bounded content, canonical tools/calls, and no credential, alias, object-address, or raw-event leakage.

External follow-ups

• The platform convenience tools/tool_calls arrays remain empty despite canonical Strands definitions/current-turn calls and connected tool spans.
• Backend ingestion projects the controlled Superagent failure and enclosing Strands workflow root as success/200 even though package-owned spans retain their native failed status and diagnostics.
• Strands Agent records remain common-only by contract, so model and usage stay on authoritative child chat spans and the UI may display unknown-model for the Agent.
• The optional Daytona repository scan remains credential-gated because DAYTONA_API_KEY is unavailable; broader Temporal continue-as-new/update/cancellation/remote-service cases remain future coverage.
