fix(server): give agents their workspace id as PASEO_WORKSPACE_ID

Agents got PASEO_AGENT_ID and PASEO_AGENT_CWD but not their workspace id, so an
agent couldn't rename or archive its own workspace, or name it to create_agent,
when several workspaces share its cwd. The launch env now sets
PASEO_WORKSPACE_ID whenever the agent has a workspace, including on resume after
a daemon restart, where the id now comes from the stored record. OpenCode treats
it as a per-session key, so it doesn't force a dedicated server.

+Inside an agent session, `PASEO_WORKSPACE_ID` holds the agent's own workspace ID, so an agent can run `paseo workspace rename "$PASEO_WORKSPACE_ID" "Auth rework"` or `paseo workspace archive "$PASEO_WORKSPACE_ID"` even when other workspaces share its directory.
+
 Add `--forge <name>` to PR checkout when Paseo cannot infer the forge from the source checkout. See [Git worktrees](/docs/worktrees) for setup hooks and services.

+在 Agent 会话中，`PASEO_WORKSPACE_ID` 保存该 Agent 自己的工作区 ID。即使其他工作区共享同一个目录，Agent 也可以运行 `paseo workspace rename "$PASEO_WORKSPACE_ID" "Auth rework"` 或 `paseo workspace archive "$PASEO_WORKSPACE_ID"`。
