docs(tui): unify help, anatomy, and preset operations

[huangzesen]

Summary

This is the single combined documentation/skills PR requested for review.

Help and runtime anatomy

• expand lingtai-tui-help into a thin discoverable umbrella for the stable TUI mental model and machine-readable + human feature routing
• make the close-TUI boundary explicit: normal UI exit does not stop a running agent, lifecycle changes stay explicit, and ordinary persistence does not default to launchd
• align lingtai-tui-anatomy with the repo-root ANATOMY.md as normative owner instead of duplicating the convention
• add exact same-repo quit/launch/attach/lifecycle/inventory/Portal source anchors and focused population/routing tests

Preset guidance

• keep lingtai-preset-skill as one thin dual-axis router: exactly 12 source-derived provider children plus 5 operation children (saved-presets, endpoint-capabilities, availability-save-gate, activation-session-refresh, troubleshooting-migration)
• keep provider pages limited to provider/model/auth/API/capability facts while centralizing shared saved-preset, probe/save, activation, and troubleshooting behavior in the operation axis
• expand codex-pool with v1/v2 pool semantics, sticky weighted selection, safe non-secret inspection, authorization/backup/compare/atomic-replace/parser-validation boundaries, and the explicit refresh/new-session activation step
• document the real Codex app-server quota query route (initialize → account/rateLimits/read with params: null), safe per-window fields, and the dated/model/route-qualified context-window evidence without treating it as timeless
• update preset Anatomy and source-derived regression tests so the 12-provider/5-operation taxonomy, source anchors, optional-tier rule, conditional OpenRouter vision path, and volatile Codex contracts cannot drift silently

Validation

Parent final gate:

• cd tui && go test ./... -timeout 300s — PASS, all 14 packages
• focused preset router/vision tests — PASS
• go build ./... — PASS
• go vet ./... — PASS
• gofmt / git diff --check — PASS
• YAML frontmatter: 19 files PASS
• parent catalogs: exactly 12 providers + 5 operations PASS
• portable-path scan: PASS

Frozen independent final review:

• exact base: 1dda8f4bb0cf0d80d6469f2d58557e3b37bb3d85
• full result: 28 files, +1730/-317
• frozen patch SHA256: 54ec5c88928716c53494b3ad375e2c998b989e22550e45f28251a3073ff40e35
• byte manifest: all 28 paths verified
• isolated reviewer: mechanically verified gpt-5.6-terra
• snapshot go test ./...: PASS, all 14 packages
• verdict: PASS — no P0, P1, or P2 findings

The three r1 findings are fixed and independently verified: OpenRouter vision is conditional on a user-owned saved preset advertising vision; no false canonical template-order promise remains; empty tier is accepted as source does.

Current main advanced after the frozen base only through Windows PowerShell installer PR #690 (3 upstream paths, zero overlap with this PR's 28 paths).

Scope

Documentation, bundled skills, Anatomy, and focused contract tests only. No runtime behavior, provider auto-routing, release, deploy, config, auth, cleanup, or lifecycle action.
