fix(install): batch parse error aborted install.bat at OCR stage

Live clean-install test caught a syntax bug in the new Tesseract setup
block: install.bat died with "so was unexpected at this time." right
after "Setting up OCR...", so OCR setup and the whole dependency
verification stage never ran.

Cause: "::" comment lines placed INSIDE parenthesised if-blocks. Two
problems compound there -- a "::" line inside a ( ) block is itself a
parse error, and any parenthesis in the comment text closes the block
early. The text "(non-zero when already installed), so after each" left
"so" as a stray token.

Fix: move every comment out of the parenthesised blocks, in both the
Tesseract block and the conda winget block added earlier. The conda one
had survived only because its text happened to contain no parentheses.

Verified: install.bat now runs to completion with exit 0 --
  Tesseract: C:\Program Files\Tesseract-OCR\tesseract.exe
  pytesseract: OK (tesserocr: DLL issue, expected)
  cv2/mss/numpy/transitions/rapidfuzz/pydantic/pytesseract/yaml/discord: OK
  All dependencies verified.
140 tests pass against the freshly created env.
