Add migration docs and fix notarization scripts to use inline credentials

Keychain profile approach doesn't work from Galaxy terminal (no interactive
auth entitlement). Switched to inline Apple ID/team/password in notarize.sh
and package.sh. Added migration-docs/ for session continuity on new machines.

+# User Preferences — George Brancovici
+
+## Communication Style
+
+- **Direct and terse.** Don't over-explain. Don't apologize. Don't ask unnecessary questions.
+- **Just do it.** When he says "run this shit yourself" — run it. Don't suggest he do it.
+- **Don't be precious.** He'll curse, be blunt, call you out. Roll with it and deliver.
+- **No hand-holding.** He's a senior engineer. Don't explain basic concepts.
+- **Action over discussion.** When something needs doing, do it. Don't present 3 options and ask which one.
+
+## Work Patterns
+
+- Works in Galaxy terminal (the app he's building) — this means some macOS interactive features (keychain dialogs, etc.) won't work from within it
+- Uses zsh
+- Samsung employee (g.brancovici@samsung.com)
+- Works on macOS (arm64/Apple Silicon)
+- Python env: py312
+
+## Technical Preferences
+
+- Prefers simple standalone scripts over complex CI pipelines
+- arm64 only — no universal binary
+- Inline credentials over keychain profiles (pragmatic, gets the job done)
+- Release builds matter — he distributes the DMG
+
+## What NOT to Do
+
+- Don't ask "want me to X?" when the answer is obvious from context
+- Don't explain what went wrong in 3 paragraphs — say it in 1 sentence
+- Don't suggest he do things himself unless there's a genuine technical blocker (interactive auth, etc.)
+- Don't add caveats and disclaimers to every suggestion
+- Don't say "I apologize" — just fix it
