Enable resilient tasks in LRA samples (invocations + responses) + responses 2.0.0b1 core floor bump

[Nathandrake229]

Summary

Enable resilient-task startup recovery explicitly (set_resilient_tasks_enabled(True)) in the resilient (LRA) samples across the invocations and responses packages, with parity across both protocols. Because the responses samples now use a core 2.0.0b10 API, this PR also raises the responses package's core floor and cuts a 2.0.0b1 prep entry.

Changes

Invocations resilient samples — add set_resilient_tasks_enabled(True):

• samples/resilient_multiturn/app.py
• samples/resilient_langgraph/app.py
• samples/resilient_research/app.py

Responses resilient samples — add set_resilient_tasks_enabled(True):

• samples/sample_19_resilient_streaming.py
• samples/sample_20_resilient_steering.py
• samples/sample_21_resilient_langgraph.py
• samples/sample_22_resilient_multiturn.py

Responses package release-prep (required by the sample change):

• pyproject.toml: core floor >=2.0.0b9 → >=2.0.0b10
• _version.py: 2.0.0b0 → 2.0.0b1
• CHANGELOG.md: new ## 2.0.0b1 (Unreleased) entry documenting the dependency bump

Why

azure-ai-agentserver-core 2.0.0b10 introduced an opt-in gate for the resilient TaskManager startup recovery scan: recovery runs only when a durable task is declared or set_resilient_tasks_enabled(True) was called (an OR gate). Calling the switch explicitly in every resilient sample demonstrates the public opt-in API consistently, and keeps recovery working even if a task is registered lazily (the flag starts the periodic recovery loop at boot).

Since the responses samples now import set_resilient_tasks_enabled (a b10 API) at module top level, the responses package's core floor must be >=2.0.0b10 or the samples would fail at import under the package's minimum supported dependency — hence the floor bump + 2.0.0b1 version + CHANGELOG note (addresses the Copilot review feedback).

Note on the two packages

• Invocations samples declare user-facing @task / @multi_turn_task, so recovery runs via the task-declared branch; the flag makes the opt-in explicit and covers the lazy-registration edge.
• Responses samples enable resilience via ResponsesServerOptions(resilient_background=True). The framework already registers its internal durable tasks at ResponsesAgentServerHost construction (before app.run()), so recovery runs regardless — the flag is added for parity and to showcase the opt-in API (the added comment states this explicitly).

Validation

• All 7 sample apps compile (py_compile).
• from azure.ai.agentserver.core.tasks import set_resilient_tasks_enabled resolves against the published azure-ai-agentserver-core==2.0.0b10.
• pyproject.toml parses; responses deps resolve to azure-ai-agentserver-core>=2.0.0b10.
• Public API surface unchanged, so api.md / api.metadata.yml require no regeneration.
• Invocations core floor bump to >=2.0.0b10 already merged via Prepare azure-ai-agentserver-invocations 1.0.0b8 release #48398.

• The PR title, summary, change list, rationale, and validation describe updates only to the three invocations samples, but this also changes four responses samples. Please either remove the responses changes or update the PR metadata and validation to cover this additional package and explain the scope expansion.

from azure.ai.agentserver.core.tasks import set_resilient_tasks_enabled

• This dependency bump leaves [tool.azure-sdk-build] at lines 75–76 claiming that azure-ai-agentserver-core>=2.0.0b9 is not on PyPI and disabling mindependency. Since this PR depends on the published b10 release, that rationale is now stale and CI will still skip validating the new minimum dependency. Remove/update the stale comment and re-enable mindependency unless another documented blocker remains.
