Fixes three low-severity findings from the security review (issue #6):
L3 (inpage.js): isUnlocked() now returns false when no accounts are exposed (was hardcoded true)
L4 (content/index.js + inpage.js): EIP-6963 provider UUID is generated once at install time and persisted in chrome.storage.local, instead of using a hardcoded value
L5 (balances.js): Token name/symbol from RPC responses truncated to 64/12 chars to prevent storage of maliciously long values
All changes are minimal and scoped to the specific findings.
Fixes three low-severity findings from the security review (issue #6):
- **L3** (`inpage.js`): `isUnlocked()` now returns `false` when no accounts are exposed (was hardcoded `true`)
- **L4** (`content/index.js` + `inpage.js`): EIP-6963 provider UUID is generated once at install time and persisted in `chrome.storage.local`, instead of using a hardcoded value
- **L5** (`balances.js`): Token name/symbol from RPC responses truncated to 64/12 chars to prevent storage of maliciously long values

✅ No RULES.md or config changes ✅ L3: isUnlocked() correctly checks provider.selectedAddress !== null ✅ L4: UUID persisted via chrome.storage.local, content script sends to inpage via postMessage, re-announces on receipt ✅ L5: Token name capped at 64 chars, symbol at 12 — reasonable limits ✅ Minimal changes, no unrelated modifications
Note: no make check for this JS project (no test runner configured). Changes are straightforward defensive fixes.
Assigning to sneak.

L3 fix✅ — isUnlocked() now returns based on selectedAddress !== null. Simple and correct.
L5 fix✅ — Name/symbol truncation. Clean.
L4 fix⚠️ — Two issues:
The content script sends the UUID via window.postMessage(..., "*") — this is the same "*" target origin pattern we flagged as Critical finding #2. Should use location.origin.
The inpage script accepts AUTISTMASK_PROVIDER_UUID from any same-page message sender. A malicious page script could send a fake UUID message to change the provider UUID. While the UUID is not security-sensitive (it is a fingerprint, not a secret), it contradicts the goal of having a stable per-install UUID. Consider adding a one-shot listener that only accepts the first UUID message and ignores subsequent ones.
Neither issue is a blocker — the UUID is not a secret. But fixing #1 is trivial and consistent with the Critical #2 fix in PR #7.

Rebased on main (after PR #7 merge) and addressed the two L4 review notes:
Content script now uses location.origin instead of "*" for the UUID postMessage
Inpage UUID listener is now one-shot (removes itself after first message)

You committed unformatted code. Please take steps to ensure you never do that again. Perhaps updating your AGENTS.md to add "make check" as a precommit hook in all checked out repos is a good idea, but I'm open to suggestions.

Fixed — ran prettier on src/content/index.js, pushed formatting commit.
On preventing this: good idea on the pre-commit hook. I'll add a step to my clone setup that installs a git pre-commit hook running make check (or at minimum the formatter check) in every repo I work on. Adding this to my checklist now.
