[WIP] Update README.md for core principles formatting

[Copilot]

Thanks for asking me to work on this. I will get started on it and keep this PR's description up to date as I form a plan and make progress.

Original prompt

Problem

The README.md file contains multiple instances of "??" that should be replaced with proper icons, symbols, or formatting to make the document more professional and readable.

Changes Required

Update the README.md file with the following changes:

1. Core Principles Section (lines 16-20)

Remove the ?? prefix from each principle:

Before:

- ?? **Calm** - Breathing room, gentle neutrals, no harsh edges or visual noise
- ?? **Intentional** - Motion with purpose, no bouncing or flourish
- ?? **Local & Sovereign** - On your machine, for your mission
- ?? **Predictable** - Stable regions, consistent hierarchy
- ?? **Human** - Plain language errors, safest action first

After:

- **Calm** - Breathing room, gentle neutrals, no harsh edges or visual noise
- **Intentional** - Motion with purpose, no bouncing or flourish
- **Local & Sovereign** - On your machine, for your mission
- **Predictable** - Stable regions, consistent hierarchy
- **Human** - Plain language errors, safest action first

2. Error Messages Section (lines 234-235)

Replace ? with proper checkmark symbols:

Before:

? **Don't:** "Error: NullReferenceException at line 42"  
? **Do:** "Couldn't save your data. The connection was lost. [Retry]"

After:

**❌ Don't:** "Error: NullReferenceException at line 42"  
**✅ Do:** "Couldn't save your data. The connection was lost. [Retry]"

3. Architecture Section (lines 241-259)

Replace the malformed tree structure with proper ASCII tree characters:

Before:

CalmUI/
??? Theme/
?   ??? CalmTheme.vb          # Design system foundation
??? Components/
...

After:

CalmUI/
├── Theme/
│   └── CalmTheme.vb          # Design system foundation
├── Components/
│   ├── CalmButton.vb         # Semantic buttons
│   ├── CalmTextBox.vb        # Rounded inputs
│   ├── CalmControls.vb       # Layout helpers
│   ├── PromptCard.vb         # Guidance cards
│   ├── GuidanceStrip.vb      # Assistant panel
│   ├── LeftRail.vb           # Navigation rail
│   ├── TopCalmBar.vb         # Application bar
│   ├── BottomStatusBar.vb    # Status display
│   ├── AnimatedPanels.vb     # Animation framework
│   └── WhySourcesDrawer.vb   # Explanatory drawer
├── Forms/
│   ├── CalmChildForm.vb      # Base template
│   └── WelcomeOnboardingForm.vb
└── Messaging/
    ├── CalmMessageBox.vb     # Human dialogs
    └── ToastNotification.vb  # Quiet toasts

4. Acknowledgments Section (line 288)

Remove the ??:

Before:

Built with ?? for operators who deserve dignity.

After:

Built for operators who deserve dignity.

5. Support Section (lines 292-294)

Remove the ?? prefix from each link:

Before:

- ?? [Full Documentation](./docs/README.md)
- ?? [Issue Tracker](https://github.com/thynaptic/AUGMORY/issues)
- ?? [Discussions](https://github.com/thynaptic/AUGMORY/discussions)

After:

- [Full Documentation](./docs/README.md)
- [Issue Tracker](https://github.com/thynaptic/AUGMORY/issues)
- [Discussions](https://github.com/thynaptic/AUGMORY/discussions)

Expected Outcome

All placeholder "??" instances should be replaced with appropriate professional formatting, making the README more polished and readable.
