Thales Maciel 58df176148 Add persistent task workspace alpha
Start the first workspace milestone toward the task-oriented product without changing the existing one-shot vm_run/pyro run contract.

Add a disk-backed task registry in the manager, auto-started task workspaces rooted at /workspace, repeated non-cleaning exec, and persisted command journals exposed through task create/exec/status/logs/delete across the CLI, Python SDK, and MCP server.

Update the public contract, docs, examples, and version/catalog metadata for 2.1.0, and cover the new surface with manager, CLI, SDK, and MCP tests. Validation: UV_CACHE_DIR=.uv-cache make check and UV_CACHE_DIR=.uv-cache make dist-check.

# Public Contract
This document defines the supported public interface for `pyro-mcp` `2.x`.
## Package Identity
- Distribution name: `pyro-mcp`
- Public executable: `pyro`
- Public Python import: `from pyro_mcp import Pyro`
- Public package-level factory: `from pyro_mcp import create_server`
## CLI Contract
Top-level commands:
- `pyro env list`
- `pyro env pull`
- `pyro env inspect`
- `pyro env prune`
- `pyro mcp serve`
- `pyro run`
- `pyro task create`
- `pyro task exec`
- `pyro task status`
- `pyro task logs`
- `pyro task delete`
- `pyro doctor`
- `pyro demo`
- `pyro demo ollama`
Stable `pyro run` interface:
- positional environment name
- `--vcpu-count`
- `--mem-mib`
- `--timeout-seconds`
- `--ttl-seconds`
- `--network`
- `--allow-host-compat`
- `--json`
Behavioral guarantees:
- `pyro run <environment> -- <command>` defaults to `1 vCPU / 1024 MiB`.
- `pyro run` fails if guest boot or guest exec is unavailable unless `--allow-host-compat` is set.
- `pyro run`, `pyro env list`, `pyro env pull`, `pyro env inspect`, `pyro env prune`, and `pyro doctor` are human-readable by default and return structured JSON with `--json`.
- `pyro demo ollama` prints log lines plus a final summary line.
- `pyro task create` auto-starts a persistent workspace.
- `pyro task exec` runs in the persistent `/workspace` for that task and does not auto-clean.
- `pyro task logs` returns persisted command history for that task until `pyro task delete`.
## Python SDK Contract
Primary facade:
- `Pyro`
Supported public entrypoints:
- `create_server()`
- `Pyro.create_server()`
- `Pyro.list_environments()`
- `Pyro.pull_environment(environment)`
- `Pyro.inspect_environment(environment)`
- `Pyro.prune_environments()`
- `Pyro.create_vm(...)`
- `Pyro.create_task(...)`
- `Pyro.start_vm(vm_id)`
- `Pyro.exec_vm(vm_id, *, command, timeout_seconds=30)`
- `Pyro.exec_task(task_id, *, command, timeout_seconds=30)`
- `Pyro.stop_vm(vm_id)`
- `Pyro.delete_vm(vm_id)`
- `Pyro.delete_task(task_id)`
- `Pyro.status_vm(vm_id)`
- `Pyro.status_task(task_id)`
- `Pyro.logs_task(task_id)`
- `Pyro.network_info_vm(vm_id)`
- `Pyro.reap_expired()`
- `Pyro.run_in_vm(...)`
Stable public method names:
- `create_server()`
- `list_environments()`
- `pull_environment(environment)`
- `inspect_environment(environment)`
- `prune_environments()`
- `create_vm(...)`
- `create_task(...)`
- `start_vm(vm_id)`
- `exec_vm(vm_id, *, command, timeout_seconds=30)`
- `exec_task(task_id, *, command, timeout_seconds=30)`
- `stop_vm(vm_id)`
- `delete_vm(vm_id)`
- `delete_task(task_id)`
- `status_vm(vm_id)`
- `status_task(task_id)`
- `logs_task(task_id)`
- `network_info_vm(vm_id)`
- `reap_expired()`
- `run_in_vm(...)`
Behavioral defaults:
- `Pyro.create_vm(...)` and `Pyro.run_in_vm(...)` default to `vcpu_count=1` and `mem_mib=1024`.
- `Pyro.create_task(...)` defaults to `vcpu_count=1` and `mem_mib=1024`.
- `allow_host_compat` defaults to `False` on `create_vm(...)` and `run_in_vm(...)`.
- `allow_host_compat` defaults to `False` on `create_task(...)`.
- `Pyro.exec_vm(...)` runs one command and auto-cleans that VM after the exec completes.
- `Pyro.exec_task(...)` runs one command in the persistent task workspace and leaves the task alive.
## MCP Contract
Primary tool:
- `vm_run`
Advanced lifecycle tools:
- `vm_list_environments`
- `vm_create`
- `vm_start`
- `vm_exec`
- `vm_stop`
- `vm_delete`
- `vm_status`
- `vm_network_info`
- `vm_reap_expired`
Task workspace tools:
- `task_create`
- `task_exec`
- `task_status`
- `task_logs`
- `task_delete`
Behavioral defaults:
- `vm_run` and `vm_create` default to `vcpu_count=1` and `mem_mib=1024`.
- `task_create` defaults to `vcpu_count=1` and `mem_mib=1024`.
- `vm_run` and `vm_create` expose `allow_host_compat`, which defaults to `false`.
- `task_create` exposes `allow_host_compat`, which defaults to `false`.
- `vm_exec` runs one command and auto-cleans that VM after the exec completes.
- `task_exec` runs one command in a persistent `/workspace` and leaves the task alive.
## Versioning Rule
- `pyro-mcp` uses SemVer.
- Environment names are stable identifiers in the shipped catalog.
- Changing a public command name, public flag, public method name, public MCP tool name, or required request field is a breaking change.
