docs(skill): update inkreach-teable skill for fixed field routes + select-choice dependency

- cli-reference.md: field get/update/delete now <tableId> <fieldId>;
  new field visible-choices command; note --options goes via convert API
- tables-fields.md: correct update/delete signatures; options-rewrite
  semantics (convert API, whole-replace not merge); new section on
  select-choice visibilityFilter dependency (read/write/evaluate,
  backend 400 guards, write-time enforcement message)

 | Detail | Rule |
 |--------|------|
-| `--name` only | Convenience; for other props use `--options` |
+| `--name` only | Uses the PATCH update API (name/description only) |
-| `--options` merge | Partial updates; omitted keys are preserved |
+| `--options` | Rewrites options via the **convert** API (`PUT …/field/:fid/convert`) — the PATCH update API strips `options` by design. CLI auto-fetches the field's current type; omitted keys are **replaced whole**, not merged |
+| `--name` + `--options` | Both applied via one convert call |
 | `field delete` | Irreversible — all cell data in that field is lost |
 
+### Select-choice dependency (visibilityFilter) — 2026-08
+
+Single/multiple-select choices may carry a `visibilityFilter` making them visible only when another select field matches:
+
+```json
+{"choices":[{"id":"choA","name":"墨盒","visibilityFilter":{
+  "filterSet":[{"fieldId":"fldDeviceType","operator":"is","value":"choPrinter"}]}}]}
+```
+
+- **Read config**: `inkreach-teable field get <tableId> <fieldId>` → `options.choices[].visibilityFilter`
+- **Write config**: `field update --options` (convert API). Backend rejects self-reference (`Self-reference in visibilityFilter is not allowed`) and dependency cycles (`Dependency cycle detected…`) with 400 — enforced on both V1 and V2 paths since fix `26ed1f732`
+- **Evaluate for a record**: `inkreach-teable field visible-choices <tableId> <recordId> <fieldId>` → choices currently selectable
+- **Write-time enforcement**: writing a record value that fails its visibility condition → 400 `Option "X" does not meet the current row conditions and cannot be selected.`
