feat: add inkreach CLI + inkreach-teable-ops skill

A self-built CLI and companion agent skill for operating a deployed
inkreach-teable instance — configuring tables, fields, records, views, and
the project's OWN automation engine.

Why not the official 'teable' CLI:
  inkreach-teable's automation is self-built with a different contract:
  - conditions (not filter), fieldIds (not watchFieldIds)
  - recordCondition (not recordMatchesConditions)
  - webhook route /api/webhook/{baseId}/{wfId} (not the /base//workflow/ form)
  - scheduledTime backend honors only timing.type + timing.interval
  The official CLI targets the upstream contract and 404s/misconfigures here.
  Table/field/record/view APIs ARE upstream-compatible, but automation is not.

inkreach CLI (packages/inkreach-cli/):
  - Node.js + commander, zero extra runtime deps
  - Uses node:http (NOT fetch — Node 24 fetch drops Authorization header)
  - Commands: auth (login/status/token), base/table/field/record/view,
    workflow (list/get/create/update/delete/activate/deactivate/test),
    trigger set (8 types, builds correct config keys), action add/update/delete
    (6 types), secret, runs (list/get/rerun), fire (button-click/webhook), sql
  - --json mode for agent parsing; GET->modify->PUT whole-graph for node edits
  - Verified end-to-end: create workflow -> set webhook trigger -> add script
    action -> activate -> fire webhook -> runs list (succeeded)

inkreach-teable-ops skill (.agents/skills/inkreach-teable-ops/):
  - SKILL.md entry: module map, routing rules, 11 key constraints (the real
    contract keys), execution rules, error recovery
  - guides/: cli-reference, automation-guide, tables-fields, instance-access,
    development (build/restart, known gotchas)
  - api-reference/: trigger-types (8 triggers, exact config), action-types
    (6 actions, sandbox globals), field-types (21 types incl. Button)
  - metadata.json + install.sh
