[Agents extensions] Endpoint changes

[trangevi]

Migrate the rest of the vnext handling over to the new agents endpoints

[Copilot]

Pull request overview

Migrates remaining “vnext” hosted-agent interactions in the azure.ai.agents extension to the newer session-based agent endpoints, removing agent-version scoping where it’s no longer required.

Changes:

• Updated agent API operations to use new session/file endpoints and removed agentVersion from several client method signatures.
• Adjusted monitor and files commands to call the updated client methods (and removed the files flow’s hard requirement on agent version).
• Fixed files command PersistentPreRunE chaining to avoid Cobra recursion and added a regression test.

File	Description
cli/azd/extensions/azure.ai.agents/internal/pkg/agents/agent_api/operations.go	Switches session log streaming and session file operations to the new endpoint shapes and drops agentVersion parameters.
cli/azd/extensions/azure.ai.agents/internal/cmd/monitor.go	Updates session logstream call site to match the new client signature.
cli/azd/extensions/azure.ai.agents/internal/cmd/files.go	Fixes PersistentPreRunE chaining (prevents infinite recursion) and updates file-operation calls to the new endpoints/signatures.
cli/azd/extensions/azure.ai.agents/internal/cmd/files_test.go	Adds a regression test to ensure files subcommands don’t trigger PersistentPreRunE recursion.

Endpoint migration and PersistentPreRunE fix both look correct - clean change overall.

monitor.go:96-102: info.Version is validated unconditionally, but session logstream (line 152) no longer needs it. If version metadata isn't set, monitor --session fails with "agent version could not be resolved" even though the API call works without it. Consider deferring the version check to the container-logstream branch only (after the sessionID == "" check at line 161).

Minor: resolveFilesContext still sets Version: info.Version (~line 158) though no file operation reads it anymore. The help text (line 76) also still says "name, version, endpoint" - could drop "version". Small cleanup for a follow-up.
