Feature: Direct-to-Disk Take Extraction

As a user with S1100 or S3000 DD-recorded disk images
I want to extract Direct-to-Disk (DD) recordings as WAV files from the web UI
So that I can recover and use legacy DD takes in modern DAWs

Acceptance Criteria

Scenario: List DD takes on a disk image

Given a disk image with S3000 DD takes
When I open it in the Disk Browser
Then I see a "DD Takes" section with each take listed by index and name
And each take shows its duration in seconds (from tinfoi output)

Scenario: Extract a single DD take to WAV

Given a disk image with DD takes
When I select a take and click "Export to WAV"
Then a WAV file is created matching the take's sample rate and duration
And it plays back correctly in the browser audio player

Scenario: Extract all DD takes in batch

Given a disk image with 12 DD takes
When I click "Export All DD Takes to WAV"
Then 12 WAV files are created in the output directory
And each is named "<take-index>_<take-name>.wav"

Implementation

akaiutil commands: tinfoall for listing, take2wavi <idx> / take2wavall for extraction
Endpoint: GET /api/browse?iso=<path>&takes=true returns takes alongside partition tree
Include audio preview capability for extracted WAVs in the web UI
Reuse existing SSE progress pattern from download queue

Karpathy Principle

Builds on the existing WAV extraction pattern and the Disk Browser tree UI. Minimal new akaiutil learning needed.
