fix(sdk-ts): add conventional commits preset dependency (#55)

## Summary
- Fixes TypeScript semantic-release failure by adding the missing
`conventional-changelog-conventionalcommits` package.
- Keeps existing release behavior unchanged; this only satisfies the
configured preset dependency.

## Root Cause
Release run failed in `Run semantic-release` with:
- `Cannot find module 'conventional-changelog-conventionalcommits'`
- failure run:
https://github.com/agentcontrol/agent-control/actions/runs/22650721414/job/65649257696

`sdks/typescript/release.config.cjs` uses `preset:
"conventionalcommits"` for both commit analyzer and release-notes
generator, which requires this package to be installed.

## Changes
- `sdks/typescript/package.json`
- add devDependency: `conventional-changelog-conventionalcommits@^9.2.0`
- `sdks/typescript/pnpm-lock.yaml`
  - lockfile update

## Validation
- `make sdk-ts-build`
- Module import check with Node 22.14:
  - `import('conventional-changelog-conventionalcommits')` => success

## Risk
- Low. Dependency-only change for release tooling.
