fix(worker): record real raw token usage per run, not the uncached remainder

task_runs.tokens_in only ever held the API's uncached "input_tokens" field
(off by a factor of ~400,000 on a resumed session), and tokens_out summed
only the last result event instead of the whole session. TaskRunner now
reads each run's cache-read/cache-write/input/output totals from the
session transcript via a new ITranscriptUsageReader.ReadSessionTotalsAsync,
storing the delta against prior runs on the same session so a --resume
doesn't double-count. New task_runs.cache_read_tokens/cache_write_tokens
columns; the Session tab now shows the raw total (what actually counts
against the 5h/7d usage limit) with a breakdown tooltip.

 ## Schema
 
-Tables: `lists`, `tasks`, `worktrees`, `list_config`, `task_runs`, `subtasks`, `app_settings`, `prime_schedules`, `daily_notes`, `week_reports`, `task_attachments`. Managed by EF Core migrations in the `Migrations/` folder. The `tasks` table holds `status`, `planning_phase` (default `none`), and `blocked_by_task_id` (FK to `tasks.id`, `ON DELETE SET NULL`). Migration `WeeklyReport` added `daily_notes`, `week_reports`, and the two new `app_settings` columns. Migration `DailyPrepMaxTasks` added the `daily_prep_max_tasks` column to `app_settings` (no new tables). Migration `AddTaskAttachments` created the `task_attachments` table. Migration `AddModelPresetsAndManualFlag` added `app_settings.model_presets` plus the `is_manual` flags on `tasks` and `lists`. Migration `AddHandlerCommitRange` added the nullable `handler_base_commit`/`handler_head_commit` columns to `tasks`. Migration `AddUsageGateAndRunModel` added `app_settings.usage_gate_five_hour_pct`/`usage_gate_seven_day_pct` (defaults 80/90) and the nullable `task_runs.model` column. Migration `AddWorktreeMergeCommit` added the nullable `worktrees.merge_commit` column. Migration `AddVerifyCommand` added the nullable `list_config.verify_command` column. `TaskRepository.DeleteAsync` and `ListRepository.DeleteAsync` also delete the on-disk attachment dir(s) via an optional `AttachmentStore` ctor param (defaults to the production store).

 ## Execution History
 
 Each CLI invocation is recorded in the `task_runs` table via `TaskRunRepository`:
-- Fields: `session_id`, input/output/cache token counts, turn count, `result` text, structured output JSON
+- Fields: `session_id`, turn count, `result` text, structured output JSON, and the four raw token
+  fields (`tokens_in`/`tokens_out`/`cache_read_tokens`/`cache_write_tokens`) — **not** read from the
+  stream-json "result" event's `usage.input_tokens` (that's only the uncached remainder of one API
+  call and undercounts the real prompt size by orders of magnitude once caching kicks in). Instead
+  `TaskRunner.ApplyUsageAsync` reads `ITranscriptUsageReader.ReadSessionTotalsAsync(sessionId)` —
+  the session transcript's cumulative totals across every assistant message — and stores the
+  **delta** against prior `task_runs` rows sharing the same `session_id`, so a `--resume`'d run
+  doesn't double-count the turns already billed to an earlier run. A missing/unreadable transcript
+  leaves all four fields `null`; it never fails the run.
 - Enables auto-retry on failure (resume last session) and multi-turn follow-up via `ContinueAsync`
