* fix(knowledge): infer MIME type from file extension in create/upsert tools

Both create_document and upsert_document forced .txt extension and
text/plain MIME type regardless of the document name. Now the tools
infer the correct MIME type from the file extension (html, md, csv,
json, yaml, xml) and only default to .txt when no extension is given.

* refactor(knowledge): reuse existing getMimeTypeFromExtension from uploads

Replace duplicate EXTENSION_MIME_MAP and getMimeTypeFromExtension with
the existing, more comprehensive version from lib/uploads/utils/file-utils.

* fix(knowledge): fix btoa stack overflow and duplicate encoding in create_document

Same fixes as upsert_document: use loop-based String.fromCharCode
instead of spread, consolidate duplicate TextEncoder calls, and
check byte length instead of character length for 1MB limit.

* fix(knowledge): allowlist text-compatible MIME types in inferDocumentFileInfo

Use an explicit allowlist instead of only checking for octet-stream,
preventing binary MIME types (image/jpeg, audio/mpeg, etc.) from
leaking through when a user names a document with a binary extension.

* fix(knowledge): remove pdf/rtf from allowlist, normalize unrecognized extensions

- Remove application/pdf and application/rtf from TEXT_COMPATIBLE_MIME_TYPES
  since these tools pass plain text content, not binary
- Normalize unrecognized extensions (e.g. report.v2) to .txt instead of
  preserving the original extension with text/plain MIME type

* fix(knowledge): handle dotfile names to avoid empty base in filename

Dotfiles like .env would produce an empty base, resulting in '.txt'.
Now falls back to the original name so .env becomes .env.txt.
