chore: set Daytona Platforms Inc. as author across packages and apps

[mislavivanda]

Why

Package/app metadata attributed a single person as author in one place and was empty or absent in others. This makes attribution uniform across the repository: Daytona Platforms Inc. <support@daytona.io>, matching what n8n-nodes-daytona, opencode-plugin, pi-extension and pydantic-ai-daytona already declared.

Metadata-only change: no code, no dependencies, no behavior. For the two published Python packages it affects the Author/Author-email fields of future releases on PyPI.

What changes

File	Before	After
packages/adk-plugin/pyproject.toml	Mislav Ivanda <mivanda@daytona.io>	Daytona Platforms Inc.
packages/langchain-data-analysis/pyproject.toml	authors = []	Daytona Platforms Inc.
apps/dify-plugin/pyproject.toml	no authors key	Daytona Platforms Inc.
apps/inngest-agentkit-coding-agent/package.json	no author key	Daytona Platforms Inc.
apps/stripe-coding-agent-template/package.json	"author": ""	Daytona Platforms Inc.

Already correct, untouched: n8n-nodes-daytona, opencode-plugin, pi-extension, pydantic-ai-daytona.

Deliberately not changed

• apps/dify-plugin/manifest.yaml (author: daytonaio) — this is the Dify marketplace org handle, not a display name. Changing it would affect plugin ownership/publishing on the marketplace.
• packages/n8n-nodes-daytona/dist/package.json — untracked build artifact.

Note on the three manifest dialects

The touched files use three different author syntaxes, and using the wrong one breaks the build:

• PEP 621 (adk-plugin, dify-plugin): authors = [{name = "...", email = "..."}]
• Poetry (langchain-data-analysis): authors = ["Name <email>"] — plain strings, not tables
• npm (inngest, stripe): "author": "..." string

Verification

• Both published Python packages were built and their metadata inspected:
  • daytona_adk-0.2.0 → Author-email: "Daytona Platforms Inc." <support@daytona.io>
  • langchain_daytona_data_analysis-0.2.0 → Author: Daytona Platforms Inc. / Author-email: support@daytona.io
• dify-plugin/pyproject.toml validated through setuptools' PEP 621 reader; poetry-core parsed the langchain project successfully.
• Both package.json files parsed as valid JSON.
• Repo-wide sweep confirms every tracked manifest now declares an author.

Release impact

None — chore: produces no release-please version bump, so no release is cut for the touched packages.

Summary by cubic

Standardizes author metadata to "Daytona Platforms Inc. support@daytona.io" across manifests for consistent attribution. Old: mixed/empty authors; New: org author everywhere; side effect: future PyPI releases show the org as Author/Email; no code, dependency, or runtime impact.

• Changed manifests: packages/adk-plugin/pyproject.toml (individual → org), packages/langchain-data-analysis/pyproject.toml (empty → org), apps/dify-plugin/pyproject.toml (added org), apps/inngest-agentkit-coding-agent/package.json (added org), apps/stripe-coding-agent-template/package.json (empty → org).
• Not changed: apps/dify-plugin/manifest.yaml keeps marketplace handle daytonaio.
• Release: no version bumps or publishes.
