refactor: split jobs_view, drop YAML migration, update docs (T6.1-T6.4)

T6.1: split jobs_view.go into three files — jobs_view_helpers.go (pure
helpers) and jobs_view_details.go (detailsPanel struct with widget
creation, update, clear, and container methods) — bringing jobs_view.go
from 459 to ~200 lines.

T6.2: remove stale YAML upgrade note from README; drop *.yaml from
.dockerignore.

T6.3: delete YAML shadow structs (yamlConfig/yamlJob/yamlJobsFile),
importYAMLConfig/importYAMLJobs, legacy path constants, and all
YAML-import tests; run go mod tidy to remove go.yaml.in/yaml/v4.

T6.4: refresh ARCHITECTURE.md — JSON storage references, new Key Domain
Concepts section (per-job overlap policy, run-time statistics + log
seeding, persisted pause flag, jobs_view split).

+
+## Key Domain Concepts
+
+### Per-job overlap policy
+
+`domain.Job` carries an `OverlapPolicy` field (`json:"overlap_policy,omitempty"`).
+When non-empty it overrides the global `Config.OverlapPolicy` for that job alone.
+Empty means inherit the global default. `app.Service.RunDue` resolves the
+effective policy per job: it uses `job.OverlapPolicy` when set, otherwise falls
+back to `store.Config.OverlapPolicy`. `normalizeJob` in `app/operations.go` leaves
+the field empty on new jobs so the inherit semantics are preserved.
+
+### Run-time statistics
+
+`domain.JobRuntime` holds a rolling aggregate updated after each run:
+
+| Field | Meaning |
+|-------|---------|
+| `RunCount` | total runs recorded |
+| `FailCount` | runs that exited non-zero |
+| `LastDurationMS` | wall-clock time of the most recent run |
+| `AvgDurationMS` | mean over all runs with a recorded duration |
+| `MaxDurationMS` | longest recorded run |
+
+`runner.RunJob` measures the wall-clock start→finish and sets `DurationMS` on
+the returned `RunRecord`. `runner/logfile.go` writes a `duration` line into the
+log file header alongside the existing `state` line.
+
+On startup, `runner.SeedStats` scans each job's log files (matched by the
+`_<sanitized name>.log` suffix, bounded by `Config.MaxLogFiles`) and folds the
+parsed `state`/`duration` headers into a `runner.StatSeed` map. `NewService`
+applies those seeds to the runtime map before the first scheduler tick, so the
+details panel shows accumulated run history immediately after a restart.
+Older log files that pre-date the `duration` header are tolerated: the run is
+counted but the timing is skipped.
+
+### Persisted global pause
+
+`domain.Config` carries a `Paused bool` field (`json:"paused,omitempty"`).
+`app.Service.SetGlobalPause` writes the new value into `store.Config` and calls
+`SaveConfig`, so the paused state survives a restart. `NewService` initialises
+`s.paused` from `store.Config.Paused` and applies the paused next-run text to
+all runtimes before the first tick, ensuring the UI shows the correct state from
+the moment the window opens.
+
+### `jobs_view.go` file structure
+
+`src/ui/jobs_view.go` is split across three files to stay within the ~250-line
+size guideline:
+
+| File | Contents |
+|------|----------|
+| `jobs_view.go` | `newJobsView` — list, toolbar, button wiring, and layout |
+| `jobs_view_details.go` | `detailsPanel` struct — widget creation, `update`, `clear`, `container` |
+| `jobs_view_helpers.go` | Pure helpers — `filteredJobIndexes`, `folderOptions`, `filterValue`, `indexOfID`, `lastJobLogs` |
