docs: Fix broken Unicode emoji rendering across 122+ markdown files ([U+XXXX] → actual emoji)

[Foundup]

Problem

Emoji characters across 122+ markdown files are rendering as broken Unicode escape text [U+XXXX] instead of actual emoji characters. This makes documentation hard to read and looks unprofessional.

Example (ROADMAP.md line 1)

Current: # [U+1F310] FoundUps Intelligent Internet Orchestration System
Expected: # 🌐 FoundUps Intelligent Internet Orchestration System

Common broken patterns found

Escape Text	Should Be	Meaning
[U+1F310]	🌐	Globe
[U+1F300]	🌀	Cyclone/WRE
[U+1F4BB]	💻	Computer
[U+1F4E1]	📡	Satellite
[U+2502]	│	Box drawing vertical
[U+1F6A7]	🚧	Construction
[U+1F984]	🦄	Unicorn
[U+1F52E]	🔮	Crystal ball
[U+1F3AD]	🎭	Performing arts
[U+1F3D7]	🏗️	Building construction
[U+1F4BC]	💼	Briefcase
[U+1F3AC]	🎬	Clapper board
[U+1F4F1]	📱	Mobile phone
[U+1F31F]	🌟	Glowing star
[U+1F536]	🔶	Large orange diamond
[U+1F4C1]	📁	File folder
[U+1F3B5]	🎵	Musical note
[U+1F528]	🔨	Hammer
[U+1F3B2]	🎲	Game die
[U+26A0]	⚠️	Warning

Also affected: ASCII art box-drawing characters [U+2502], [U+2500], [U+250C], [U+2514], [U+2510], [U+2518], [U+251C], [U+2524], [U+252C], [U+2534], [U+253C] used in diagrams.

And text-tag emoji aliases: [TARGET], [OK], [DATA], [AI], [BOT], [REFRESH], [ROCKET], [HANDSHAKE], [LINK], [IDEA], [CLIPBOARD], [NOTE], [BIRD], [LIGHTNING], [ALERT], [TERMINAL], [UP] — these should map to their corresponding emoji: 🎯, ✅, 📊, 🤖, 🤖, 🔄, 🚀, 🤝, 🔗, 💡, 📋, 📝, 🐦, ⚡, 🚨, 💻, 📈

Root Cause

The wsp_documentation_guardian.py and discovery_feeder.py sanitizers were converting real emoji to [U+{ord(char):04X}] safe representations (see lines 260-261 in holo_index/qwen_advisor/orchestration/src/wsp_documentation_guardian.py). This was intended for safe processing but was applied to .md documentation files where emojis should render properly.

The README.md is not affected because it was edited separately — but ROADMAP.md, modules/ROADMAP.md, and 120+ other docs were hit.

Scope

122 markdown files contain [U+1F...] broken emoji patterns (GitHub code search: [U+1F path:*.md).

Priority files (public-facing / high-traffic)

1. ROADMAP.md — 12 instances (root project roadmap)
2. modules/ROADMAP.md — 14 instances
3. modules/README.md — 3 instances
4. docs/foundups_vision.md — 21 instances
5. prompt/README.md — 3 instances
6. utils/README.md — 4 instances

Other affected areas

• WSP_framework/ docs
• WSP_knowledge/ docs
• Module-level README.md and ROADMAP.md files across all enterprise domains
• docs/ analysis and architecture documents

Fix Approach

1. Manual fix for priority files (ROADMAP.md, modules/ROADMAP.md, etc.) — replace all [U+XXXX] with actual Unicode chars
2. Script-based batch fix for remaining 117 files using regex: \[U\+([0-9A-Fa-f]{4,5})\] → chr(int(match, 16))
3. Fix the guardian: Update wsp_documentation_guardian.py to skip .md files or preserve emojis in markdown
4. Add CI check: Prevent [U+ patterns from being committed to .md files in future
