docs(daemon): align roadmap with web-first client strategy

[chiga0]

Summary

• Update daemon docs to reflect the 2026-05-19 decision: native local TUI stays on the direct runtime path, while qwen serve prioritizes remote web chat and web terminal.
• Raise remote web chat + web terminal to an explicit technical POC track that can start in parallel with P0 daemon must-haves/state CRUD, while production readiness still waits for the P0/P1 contract work.
• Reframe client/render work around web clients plus shared terminal render core instead of default-migrating TUI/channel/IDE to daemon transport.
• Mark #4202/#4203/#4199 as default-off spikes/future references and flag #4261/#4266/#4267 as draft work that should be closed, deferred, or mined for reusable render-core pieces.

Validation

• git diff --check
• roadmap text scan for stale “all clients migrate to daemon” wording

关闭。方向完全正确——native TUI 直连长期保留 + Mode B 优先 web chat / web terminal + channel/IDE 继续 --acp 后置评估，与 #4303 / #3803 reply 4483031818 / #4175 reply 4483033542 上推的 zero-cost abstraction 立场一致。

此 PR 重写的 6 文件均已变动，rebase 冲突面较大。

精炼表述（"两条长期链路 + 一个 parking lot" 表格 / @qwen-code/client-render source-independent render core 命名 / native TUI direct + local web daemon lifecycle 拆分）值得作为单独 commit 吸收，不通过本 PR 走。
