chore: release v1.34.0 (#280)

Release **v1.34.0** — bundles the two grouped PRs now on `main`.

## Included
- **#276** (`Changed`) — content-anchored fixture matching; `turnIndex`
is a non-fatal disambiguator, not a hard reject gate. New
`turnIndexRelaxed` diagnostic + one-shot warn;
`AIMOCK_STRICT_TURN_INDEX=1` restores strict replay. Record path stays
strict.
- **#279** (`Fixed`) — Gemini Interactions mock now emits the SDK 2.x
event protocol on both streamed SSE and non-streaming paths; legacy 1.x
recorded fixtures still parse.

## Mechanics
- `package.json` → `1.34.0`; CHANGELOG `[Unreleased]` finalized under
`## [1.34.0] - 2026-06-24`.
- Merging to `main` triggers `publish-release.yml` → `npm publish` + tag
`v1.34.0`.
- Local gate green: prettier/eslint/build clean, 4055 tests pass.

Minor bump (not v2): both changes ship with back-compat/opt-out.
