fix: detect and dismiss Windows lock screen before each task (#117)

* feat: add correction flywheel (store, capture, parser, controller hooks)

Implements the correction flywheel MVP:

- correction_store.py: JSON-file-based correction library with
  save/find (fuzzy string matching via SequenceMatcher)/load_all
- correction_capture.py: Human correction capture using openadapt-capture
  Recorder (primary) with PIL screenshot fallback
- correction_parser.py: VLM call to parse before/after screenshots
  into PlanStep dict (think/action/expect)
- demo_controller.py: Added correction_store and enable_correction_capture
  params. On retry exhaustion: check correction store -> inject match,
  or capture human correction -> parse -> store -> advance
- cli.py: Added --correction-library and --enable-correction-capture flags

The loop: agent fails at step N -> correction store checked -> if match,
inject corrected step -> if no match and capture enabled, human completes
step -> Recorder captures -> VLM parses -> correction stored -> next run
retrieves it.

17 tests added, all passing. 54 existing demo_controller tests unaffected.

* fix: mock _has_recorder in correction capture test

The test was calling the real Recorder which may not have
wait_for_ready in the installed version. Mock it to use
the simple fallback path since this is a unit test.

* fix: detect and dismiss Windows lock screen before each task

Add _dismiss_lock_screen() to run_dc_eval.py that checks for LogonUI.exe
process and types the password to unlock if the screen is locked. Called
from ensure_waa_ready() after each successful probe.

This prevents eval failures when the Windows VM has been idle and the
lock screen has engaged between tasks or between sessions.
