SDK: prune the frozen legacy src/gen client of removed pty and installation surface #196

Raised in review of #194 (#151).

Problem

The legacy @aictrl/sdk client in packages/sdk/src/gen is frozen and is not regenerated: script/build.ts only regenerates src/v2/gen, and #166 notes that the headless OpenAPI has no paths. It still exports surface for subsystems that the CLI no longer has:

• packages/sdk/src/gen/sdk.gen.ts: the Pty client class (list / create / get / update / remove / connect, for /pty and /pty/{id}). No CLI server route has served these, even before chore: remove dead pty, ide, upgrade and opentui leftovers (#151) #194.

• packages/sdk/src/gen/types.gen.ts:

  • EventInstallationUpdated and EventInstallationUpdateAvailable (lines ~10-24)
  • Pty, plus EventPtyCreated / Updated / Exited / Deleted (~627-663)
  • their entries in the Event union (~673-703)

  chore: remove dead pty, ide, upgrade and opentui leftovers (#151) #194 removes the only code that published these events (src/cli/upgrade.ts, which had no importers, and src/pty), so nothing ever emitted them.

The regenerated src/v2/gen already has none of this.

Why it was not done in #194

createAictrlClient from the root @aictrl/sdk export uses the legacy client, which is also the client handed to plugins. Removing exported types and classes is a public type change for @aictrl/sdk and needs its own version bump. It fits with the regeneration and release in #166.

Acceptance

• The Pty class and the Pty* request/response types are gone from src/gen/sdk.gen.ts and src/gen/types.gen.ts. Alternatively, the legacy src/gen client is removed in favour of v2.
• EventInstallation*, EventPty* and Pty are gone from the Event union.
• bun turbo typecheck passes, and the @aictrl/sdk version bump matches the impact.
