v2.2-paseo-providers: Paseo provider stack + v2.2.1 pane-scoped chat fixes

Ship Paseo-equivalent provider snapshot, AgentComposerBar, ACP dispatch
rewrite with streaming/persist, permission prompts, and agent commands.
Follow-up: pane-scoped chat resolution, CoderMessageList tool timeline,
WS user-delta replace, and inference orphan tool_call stripping.
Archive openspec v2-2; update CHANGELOG and CURRENT.

* ACP dispatch — runs ACP-capable agents (opencode, goose) directly on the host.
* ACP dispatch — runs ACP-capable agents directly on the host.
*
* v2.1.1: BooCoder runs on the host now — agents are spawned directly,
* no SSH needed. Uses @agentclientprotocol/sdk for structured JSON-RPC.
*
* Flow:
* 1. Spawn `opencode acp` (or `goose acp`) in the worktree
* 2. Wrap child's stdin/stdout into NDJSON streams
* 3. Create a ClientSideConnection from the SDK
* 4. Initialize → newSession → prompt(task)
* 5. Collect session updates (tool calls, text output)
* 6. On prompt completion → return collected output
* v2.3: Paseo-aligned tool lifecycle — stable toolCallId, merge on
* tool_call_update, reasoning stream, worktree FS client, persist-ready snapshots.
