chore: bump remaining version surfaces to 1.34.0 (#281)

Follow-up to the v1.34.0 release (#280): the release commit bumped
`package.json` + `CHANGELOG.md` but missed the other 4 version surfaces,
leaving them drifted at 1.33.0.

Bumps to 1.34.0:
- `.claude-plugin/plugin.json`
- `.claude-plugin/marketplace.json` (`^1.34.0`)
- `charts/aimock/Chart.yaml` (`appVersion`)
- `packages/aimock-pytest/src/aimock_pytest/_version.py`
(`AIMOCK_VERSION`) — functional: pytest default-download users would
otherwise get 1.33.0 (old SDK 1.x Gemini Interactions shapes) and fail
against the v2 migration in #279.

No republish — `package.json` is already 1.34.0 on npm; this only
realigns downstream surfaces.
