fix: Replace hardcoded 'Daniel' user references with generic terms

[neilsoult]

Summary

• Replaces hardcoded "Daniel" user identity references with generic "the user" terminology
• Renames danielPreferences variable to principalPreferences
• Updates file references from ABOUT_DANIEL.md to ABOUT_PRINCIPAL.md

This allows PAI to work correctly for all users regardless of their configured principal.name in settings.json.

Changes

Agent Files (11 files in Packs/pai-agents-skill/src/agents/):

• Changed "Daniel needs to hear you speak" → "the user needs to hear you speak"
• Changed "tell Daniel it's ready" → "tell the user it's ready" (Engineer.md)

Hook Files:

• RelationshipMemory.hook.ts: Renamed variable and updated docs
• RelationshipReflect.ts: Updated file reference

What's NOT Changed

• Author attribution ("Author: Daniel Miessler") - correct as-is
• Voice name references ("Daniel" ElevenLabs voice) - correct as-is
• Repository URLs (danielmiessler/PAI) - correct as-is

Test plan

• Verify agent voice notifications work with custom principal.name
• Verify RelationshipMemory hook runs without errors
• Verify no remaining hardcoded user identity references

Fixes #555

Testing Evidence

1. TypeScript Compilation ✅

$ bun build RelationshipMemory.hook.ts
Bundled 7 modules in 5ms
RelationshipMemory.hook.js  20.31 KB  (entry point)

2. Variable Rename Verification ✅

$ grep -n "principalPreferences" RelationshipMemory.hook.ts
133:  let principalPreferences: string[] = [];
146:        principalPreferences.push(snippet);

3. No Remaining Hardcoded User References ✅

$ grep -ri "daniel needs\|tell daniel" Packs/
(no output - all references removed)

4. Files Changed Summary

• 11 agent definition files: 1-line change each (Daniel → the user)
• Engineer.md: 2 changes (line 74 and line 184)
• RelationshipMemory.hook.ts: Variable renamed, docs updated
• RelationshipReflect.ts: File reference updated

All changes are text replacements only - no logic changes.

Not sure, but it might be intended. E.g. Packs/pai-agents-skill/src/agents/Engineer.md contains Daniel reference while release file Releases/v2.5/.claude/agents/Engineer.md has it substituted. Maybe it's easier for Daniel to develop with Kai and then apply such modifications.
