chore(publish): prep 15 packages for first npm publish at 0.6.2

[telivity-otaip]

Summary

Preparation for the first-ever npm publish of the `@otaip/*` scope. Found two structural blockers during pre-publish audit that would have bricked every consumer on `npm install`; fixed them both.

Blockers fixed

1. Wrong module type on 11 of 15 packages.
`core`, `agents-platform`, `agents-tmc`, and all nested `agents/*` except `lodging` lacked `"type": "module"`. With tsup configured `--format esm --dts`, that produced `dist/index.mjs` + `dist/index.d.mts`, but `package.json` said `main: "./dist/index.js"` and `types: "./dist/index.d.ts"`. Consumers would hit `Cannot find module`.

Fix: add `"type": "module"` to all 15 so tsup emits `index.js` / `index.d.ts` matching the declared fields. Verified each package's `main` and `types` now resolve to a real file.

2. Types exported from src (which doesn't ship).
All 15 packages had `exports["."].types: "./src/index.ts"`. But `files: ["dist"]` excludes `src/` from the tarball, so TypeScript users would get no types.

Fix: point `exports["."].types` at `./dist/index.d.ts`.

Version sync

All 15 workspace packages were still at `0.6.0` while root was `0.6.2`. Bumped them all to `0.6.2` so the first publish is coherent.

Dry-run output

```
$ pnpm -r publish --access public --no-git-checks --dry-run

• @otaip/adapter-duffel@0.6.2
• @otaip/agents-booking@0.6.2
• @otaip/agents-exchange@0.6.2
• @otaip/agents-lodging@0.6.2
• @otaip/agents-platform@0.6.2
• @otaip/agents-pricing@0.6.2
• @otaip/agents-reconciliation@0.6.2
• @otaip/agents-reference@0.6.2
• @otaip/agents-search@0.6.2
• @otaip/agents-settlement@0.6.2
• @otaip/agents-ticketing@0.6.2
• @otaip/agents-tmc@0.6.2
• @otaip/cli@0.6.2
• @otaip/connect@0.6.2
• @otaip/core@0.6.2
  ```

Also inspected the `@otaip/agents-booking` tarball manifest — pnpm correctly rewrote every `workspace:*` dep to `"0.6.2"`.

What is NOT in this PR (you need to do before publishing)

1. Create the `@otaip` npm org → https://www.npmjs.com/org/create
2. Generate an automation-type npm token with read+write scope on `@otaip/*`
3. Add it to the GitHub repo as `NPM_TOKEN` → Settings → Secrets → Actions
4. Merge this PR
5. Either tag `v0.6.2` on main (triggers `release.yml` → `publish.yml`) or trigger `publish.yml` manually (workflow_dispatch)

Once published, smoke-test with:
```
npm view @otaip/core
npm view @otaip/agents-search
npm view @otaip/adapter-duffel
```

Test plan

• `pnpm -r run clean && pnpm -r run build` — all 16 packages Done
• `main` and `types` resolve to existing files on all 15 packages
• `pnpm -r publish --dry-run` — 15 @otaip/* packages at 0.6.2
• Packed tarball dependency manifest uses concrete versions, not `workspace:*`
• `pnpm test` — 3,092 pass (3 skipped)
• `pnpm -r run typecheck` — clean
• `pnpm run lint` — clean
