Description

Reviewed all messages/*/root.txt files for spelling and grammar issues. Found and fixed various typos, grammar errors, and one actual bug.

Spelling/Grammar fixes include:

• "is failed" → "has failed" (verb tense)
• "failed to determined" → "failed to determine" (infinitive form)
• "Enexpected" → "Unexpected" (typo)
• "version os LTFS" → "version of LTFS" (typo)
• "access to directory" → "access directory" (incorrect preposition)
• "look an index" → "look like an index" (missing word)
• "Reached to EOD" → "Reached EOD" (incorrect preposition)
• "The opcode" → "the opcode" (capitalization after comma)
• "Error" → "error" (mid-sentence capitalization)
• Various double periods and missing punctuation

Bug fix:

• Format specifier 0x02%x → 0x%02x in messages 30203I and 30244I
• This caused incorrect output like "M = 0x0234" instead of "M = 0x34"

Type of change
