[FEATURE]: Implement V2 session.command API #34429
Description
Feature hasn't been suggested before.
- I have verified this feature I'm about to request hasn't been suggested before.
Describe the enhancement you want to request
Implement V2 slash-command execution for sessions.
Current notes from #34359:
commands.listexists in the generated client surface.- Executing a command in a V2 session does not yet exist.
- The TUI needs command execution semantics before it can fully leave the legacy SDK.
Expected scope:
- Define how a command invocation is represented in the V2 session API.
- Resolve command names/arguments against the registered command list.
- Decide whether command results admit prompts, produce synthetic/session events, or perform direct actions.
- Return clear errors for unknown/invalid/unavailable commands.
- Add protocol/server/client exposure and tests.
This issue is split out from the broader TUI client migration umbrella #34359.

Tracker update from V2 TODO LIST (2026-07-02): Open implementation PR: #34849 — feat(core): port v2 command invocation. This appears to be the concrete session.command API implementation path for this issue. Re-test slash commands and MCP prompt command invocation after it lands.

Landed via #34849.
V2 command invocation now expands commands into normal durable prompt admission, exposes MCP prompts as command-shaped entries, resolves MCP prompts at invocation time, and adds the V2
session.commandAPI/client surface.Source update from Aiden: https://discord.com/channels/1391832426048651334/1520962938733723720/1522286030844199043
