fix: Remove all emojis from documentation for cross-platform compliance

Replaced 50+ emoji types with ASCII text markers for consistent rendering
across all terminals, editors, and operating systems:

  - Checkmarks/status: [OK], [DONE], [SUCCESS], [PASS]
  - Errors/warnings: [ERROR], [FAIL], [WARNING], [CRITICAL]
  - Actions: [DO], [DO NOT], [REQUIRED], [OPTIONAL]
  - Navigation: [NEXT], [PREVIOUS], [TIP], [NOTE]
  - Progress: [IN PROGRESS], [PENDING], [BLOCKED]

Additional changes:
  - Made paths cross-platform (~/ClaudeTools for Mac/Linux)
  - Fixed database host references to 172.16.3.30
  - Updated START_HERE.md and CONTEXT_RECOVERY_PROMPT.md for multi-OS use

Files updated: 58 markdown files across:
  - .claude/ configuration and agents
  - docs/ documentation
  - projects/ project files
  - Root-level documentation

This enforces the NO EMOJIS rule from directives.md and ensures
documentation renders correctly on all systems.
