Garry Tan 4b3bbed242 fix(security-classifier): TDZ when claude CLI is missing from PATH
The checkTranscript Promise executor in browse/src/security-classifier.ts
referenced `finish()` at the !claude early-return guard before declaring
it 5 lines later. JavaScript throws ReferenceError: Cannot access 'finish'
before initialization (TDZ) for that path, but the path is only reachable
when resolveClaudeCommand returns null inside the spawn block (a TOCTOU
window vs. the outer checkHaikuAvailable cache).

Fix: hoist `let stdout = ''`, `let done = false`, and `const finish` block
above `const claude = resolveClaudeCommand()` so finish is in scope before
any reference to it. Behavior is identical when claude is on PATH; the
fix only matters for the dormant missing-CLI degraded path.

Adds browse/test/security-classifier-tdz.test.ts as the regression guard:
clears PATH + override env vars, calls checkTranscript, asserts the result
serializes with degraded:true and a meaningful reason field.
