Move internal/backend and internal/config to pkg/ so external consumers
can import them. Remove cmd/ollie and internal/tui — they now live in
the separate ollie-tui repo which imports ollie as a library.

internal/mcp → pkg/mcp (MCP client, concrete)
internal/tools → pkg/tools (Executor interface + MCPExecutor)
internal/exec → pkg/tools/execute (builtin sandbox executor, split by tool)
Split exec.go into executor.go (sandbox runner), pipe.go (BuildPipeline/PipeStep),
tool.go (ReadTool), and code.go (execute_code is Executor.Execute with trusted=false).
All three packages are now importable by consumers outside this module.

Each backend now owns its active model via Model()/SetModel(). ChatStream
no longer takes a model string — callers use SetModel to configure it.
AgentCoreConfig.ModelName sets the backend model at construction time via
SetModel, then the field can be dropped from the live agentCore struct.

Everything not part of the agent<->frontend contract is now unexported:
- contextConfig/Builder/Stats, loopConfig, toolExecutor, confirmFn,
run, state, toolResult — internal loop/session machinery
- buildFirstPrompt, systemPrompt, builtinTools — impl details
- agentCore struct (NewAgentCore returns Core)
- Session methods (saveTo, history, rollback, compact, etc.)
- AgentEnv internal fields (mcpExec, exec, confirm, tools, etc.)
App-level utilities moved from pkg/agent to cmd/ollie:
- resolveBackendName, defaultModelForBackend, newSessionID,
agentConfigPath
RestoreSession now takes int (ctxOverhead) directly, eliminating
the need for contextConfig to be public.
