feat: surface task execution progress across Host Agent and Cloud

Host Agent now persists step-level execution detail locally (via a real
TaskMetadataStore/Timeline wired into TaskRunner) and reports a bounded
in-progress snapshot piggybacked on lease renewal. Cloud persists that
snapshot per active assignment and exposes it through the existing task
list/detail query path; Cloud Console renders it as a live badge. Host
Agent's local console gains authenticated, read-only task list and
detail/timeline pages (same-origin, server-rendered) with inlined
screenshots.

Also fixes a pre-existing gap in the shared Timeline: the actual
per-step LLM prompt is now recorded instead of the task goal, benefiting
both Runtime and Host Agent consoles. When a host uses the cloud planner
transport, each decide call's prompt and resulting tool decision are
durably logged in a new planner_decision_log table (with bounded
retention) and browsable from Cloud Console; direct-transport hosts
explicitly surface a "not reported" state.

Includes Alembic migrations 0008 (progress columns on scheduled_tasks)
and 0009 (planner_decision_log), bounded Host-Agent-local retention,
dual-backend repository parity, and Vitest + pytest coverage. Task 6.5
(manual end-to-end device verification) remains.

### Task progress storage and retention
The Host Agent persists step-by-step task execution state (metadata +
timeline screenshots) to local SQLite/files on the edge machine. These
paths are independent from the Runtime's own `tasks/tasks.sqlite3` and
do not collide when both processes run on the same host.

HOST_AGENT_TASK_PROGRESS_DB_PATH=host_agent_data/task_progress.sqlite3

HOST_AGENT_TASK_RETENTION_MAX_AGE_DAYS=7
```
- `HOST_AGENT_TASK_PROGRESS_DB_PATH` — SQLite path for the Host Agent's
task metadata store. Default: `host_agent_data/task_progress.sqlite3`.
- `HOST_AGENT_TASK_ARTIFACT_DIR` — directory for timeline screenshots and
step artifacts. Default: `host_agent_data/history`.
- `HOST_AGENT_TASK_RETENTION_MAX_COUNT` — maximum number of completed
tasks to retain. Default: `50`.
- `HOST_AGENT_TASK_RETENTION_MAX_AGE_DAYS` — maximum age in days for
retained tasks. Default: `7`. The more restrictive of count vs. age
always wins.
**Viewing live and historical task progress:**
- **Host Agent console**: Open `http://127.0.0.1:8765/tasks` for the task
list (status, device, timestamps). Click a task ID to see the detail page
with full step-by-step timeline and inlined screenshots.
- **Cloud console**: The Cloud Console task detail page shows the latest
coarse-grained progress badge (step index, status, summary) that the Host
Agent piggybacks on each lease renewal.
Treat `HOST_AGENT_CONSOLE_ALLOW_NON_LOOPBACK` as an explicit,
operator-accepted risk: the console has no built-in TLS and no rate
limiting, so a non-loopback bind exposes an unencrypted login form to
