## Summary of the Pull Request

This PR adds three parts of the original big bad global error handler
(error report builder, sanitization and internal tools UI).

### Error Report Generation

- `ErrorReportBuilder`: Produces a detailed, technical report with
system context.
- Comprehensive data: OS version, architecture, culture, app version,
elevation status, etc.
- Exception analysis: Coalesces nested exception messages and HRESULT
details for clearer diagnostics.

This is an error report generated by Windows Command Palette.
If you are seeing this, it means something went a little sideways in the
app.
You can help us fix it by filing a report at
https://aka.ms/powerToysReportBug.

(While you’re at it, give the details below a quick skim — just to make
sure there’s nothing personal you’d prefer not to share. It’s rare, but
sometimes little surprises sneak in.)

### PII Sanitization Framework

- `ErrorReportSanitizer`: Multi-layer sanitization pipeline for
sensitive data.
- Nine specialized rule providers:
- `PiiRuleProvider`: Personally identifiable information (emails, phone
numbers, SSNs).
- `ProfilePathAndUsernameRuleProvider`: Windows user profiles and
usernames.
- `NetworkRuleProvider`: IP addresses, MAC addresses, network
identifiers.
- `SecretKeyValueRulesProvider`: API keys, tokens, passwords in
key/value formats.
  - `FilenameMaskRuleProvider`: Sensitive file paths and extensions.
  - `UrlRuleProvider`: URLs and web addresses.
  - `TokenRuleProvider`: JWT and other auth tokens.
  - `ConnectionStringRuleProvider`: Database connection strings.
- `EnvironmentPropertiesRuleProvider`: Environment variables and system
properties.

### Internals Tools Page

A page in settings available in non-CI-builds:
