Documentation Quality Audit — Typo, Spacing, and Formatting Fixes

A full audit of the wiki docs and update-thread posts found a range of issues: misspellings, broken links, stray invisible Unicode characters, inconsistent heading levels, trailing whitespace, mismatched list markers, and copy-paste errors. This PR fixes them across 35 files.

Spelling / Grammar Fixes

• docs/gaming-tools.md — "Deltaune" → "Deltarune" (line in Undertale/Deltarune Tools section)
• docs/educational.md — "Diskordseгver" → "Diskordserver" (Cyrillic г (U+0433) replaced with Latin g)
• docs/educational.md — "Resources Wikipedia" → "Wiki / Resources" in the MIT Rocket Team entry
• docs/posts/WWH.md:
  • "Whats our purpose? Whats the point?" → "What's our purpose? What's the point?"
  • "we're all apart of" → "we're all a part of"
  • "its important" → "it's important"
• docs/posts/Internet-Archive.md — "its highly recommended" → "it's highly recommended"
• docs/posts/new-site.md — "feel like its the best version" → "feel like it's the best version"
• docs/posts/may-2026.md — three "its" → "it's" (open-source / officially closed / been archived)
• docs/posts/nov-2023.md — description copy-paste error: "October 2023 updates." → "November 2023 updates."

Broken / Malformed Links

• docs/gaming.md — TETR.IO Skin Database URL had a double trailing slash: tetrioplus// → tetrioplus/
• docs/posts/june-2026.md — trailing space inside the URL fmhy.net/single-page.md ) → single-page.md), which would break the link
• docs/posts/changelog-sites.md — kept the original Reddit link (revert of the earlier Discord link swap)

Stray / Invisible Unicode Characters

These are U+2060 (WORD JOINER) zero-width characters left embedded in unwanted positions:

• docs/video.md — "S⁠treaming Perfect Setup" → "Streaming Perfect Setup" (joiner removed from mid-word)
• docs/audio.md — trailing ⁠ after the synced+ GitHub link removed
• docs/educational.md — ⁠ removed from mid-description in the Rubiks Cube Guide entry
• docs/gaming.md:
  • duplicated "⁠Memorize Earth" text at end of line removed
  • "Guess Countries by ⁠Music" → "Guess Countries by Music"
• docs/posts/sept-2026.md — trailing ⁠ at end of line removed
• docs/posts/june-2026.md — ⁠ before "[SteaMidra]" and before "Fluxy Repacks" removed

Missing Characters / Spacing

• docs/posts/KeepAndroidOpen.md — "-Help this project out" → "- Help this project out" (space after list dash)
• docs/system-tools.md — "Github" → "GitHub" (capital H)

Link Text Fixes

• docs/video.md — "[ReFooty ]" → "[ReFooty]" (trailing space inside link text)

Heading Level Consistency

• docs/posts/feb-2025.md — "### Wiki Updates" → "# Wiki Updates" (was the only ### heading in a file that otherwise uses #, causing mixed heading levels)
• docs/posts/july-2024.md — "## Tournament Results" and "## [Final Results]" → "###" (the file's other headings all use ###)

List Marker / Formatting Consistency

• docs/storage.md — - [ prefixed list items in "Internet Archive Tools" → * [ to match the rest of the file
• docs/posts/sept-2026.md — * Starred → - Starred (sole asterisk bullet among dash bullets)
• docs/educational.md — the entire Go / Baduk / Weiqi section used en-dashes – as separators instead of hyphens -; all replaced for consistency with the rest of the file
• docs/posts/support-ia.md — added missing blank lines around the *** horizontal rules

Content Consistency

• docs/mobile.md — added the missing description "Free Open Source Video Players" to the mpvEx / mpvRex / mpvRx entry (every other entry in the section has one)
• docs/image-tools.md — moved an orphaned leading comma so the OCR Desktop Apps line stays on the wrapping list properly

Trailing Whitespace Removed

Trailing spaces were stripped at the end of lines across:

• docs/audio.md (1 line), docs/developer-tools.md (2 lines), docs/educational.md (17 lines), docs/gaming.md (1 line), docs/video.md (2 lines), docs/social-media-tools.md (1 line)
• Posts: july-2023, july-2025, aug-2025, jan-2025, sept-2024, sept-2025, oct-2024, oct-2025, nov-2024

Line Ending Normalization (CRLF → LF)

Three 2026 update-thread files were saved with Windows line endings (\r\n) while every other file in the repo uses LF. Converted to LF to avoid rendering/merge artifacts:

• docs/posts/july-2026.md
• docs/posts/aug-2026.md
• docs/posts/sept-2026.md
