chore: scrub internal session-handoff docs from public repo

[satyakwok]

Why

SESSION_HANDOFF.md and TODO.md were committed in the initial push 2026-04-18 and have sat in public history since. They're internal-flavored notes — Indonesian-language session log mentioning APK testing flow ("dikirim via WA"), internal file paths, operator-side TODO state. Nothing sensitive (no creds, no addresses) but doesn't belong in the public mobile-wallet repo.

What

git rm both files. No history rewrite — leaked content is non-sensitive, removing from current tree is sufficient and doesn't break consumers.

Active TODO state lives in operator's local notes; SESSION_HANDOFF exists privately. Removing public copies removes the drift risk between the two surfaces.

Test plan

• No code/build impact (markdown removal only)
• Verify nothing in the repo references these files (README, docs, CI)

📝 Walkthrough

Walkthrough

Two documentation files have been cleared of their content. SESSION_HANDOFF.md, which previously contained session handoff documentation for the Solux Wallet project, has been completely emptied. Similarly, TODO.md, which previously contained a TODO checklist with Done/In Progress/Pending sections, has also been entirely removed, including its last updated timestamp.
