feat(textrazor): scaffold plugin

[Simran-Sharma392]

Description

Initial scaffold for the TextRazor integration, generated via
pnpm run generate:plugin Textrazor. This adds the packages/textrazor/
plugin package and registers it in packages/corsair/core/constants.ts.

TextRazor (https://www.textrazor.com/) is an NLP API for entity extraction,
topic classification, and text analysis, exposed here as a single-endpoint
API-key-authenticated integration.

Closes #1034

This is an initial scaffold — implementation (real endpoints, auth wiring,
schemas) will follow in subsequent commits before this is marked ready for
review.

Checklist

• I have run pnpm lint and all checks pass
• I have run pnpm typecheck and there are no TypeScript errors
• I have run pnpm build and all packages build successfully
• I have run pnpm test and all tests pass
• I have added or updated tests where applicable
• I have added or updated necessary documentation

Screenshots / Demos (if applicable)

N/A yet — will add once endpoints are implemented.

Additional Notes

No breaking changes. New plugin package only; no changes to existing
plugins or core behavior beyond the generated registration entry.
