docs(adr): ブログ連携機能の撤去 ADR を起票（ADR-0022 / #518）

[yusuke0610]

概要

機能整理ロードマップ #517 のサブ issue #518。ブログ連携（Zenn / note 同期・記事一覧・投稿スコアリング）を撤去する方針を ADR-0022 として起票する。本 PR は ADR のみ（撤去実装は次の #519）。

背景

• 経歴書へ還流せず、一覧 + スコア表示止まりの独立した島になっている
• 投稿頻度スコアはブランクのあるユーザに逆効果になり得る
• note は RSS スクレイピング依存で外部仕様変更に弱い
• 還流のないまま lint / test / codegen / 依存追従の保守コストが継続

内容

• docs/adr/0022-remove-blog-integration.md を新規作成（Accepted）
  • ADR-0008（LLM 全撤去）の流儀に倣い、次の実装 PR [ブログ撤去 2/2] 撤去実装: backend / web / DB / codegen #519 のチェックリスト粒度で撤去対象を全量列挙（DB テーブル 3 つ / backend / web / codegen 生成物）
  • Agent への波及を既知トレードオフとして明記（context_builder._build_blog_context がブログスコアを Agent コンテキストへ注入 → 撤去で職務要約・自己PR 提案の参照データからスコアが消える。ADR-0010 の DB 非更新原則・契約は不変）
• docs/adr/README.md 索引を同一 PR で更新（現在有効な決定 + 全 ADR 一覧の両表）

受け入れ条件

• ADR が Accepted で入り、索引と整合（make lint-adr-index green）
• 撤去対象の全量が ADR から漏れなく辿れる（[ブログ撤去 2/2] 撤去実装: backend / web / DB / codegen #519 のチェックリストとして使える粒度）

CI

make ci ローカル green。差分は docs のみ。

Closes #518

Warning

Review limit reached

@yusuke0610, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 52 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Inline comments:
In `@docs/adr/0022-remove-blog-integration.md`:
- Line 24: Expand the removal inventory in ADR-0022 to explicitly list backend
task-handler paths and all related env, ErrorCode, frontend constant, and
documentation files or symbols. Match the detailed checklist style of ADR-0008
so PR `#519` can verify scheduled jobs, configuration, and stale assets are fully
removed.
- Line 72: Update the ADR’s removal prerequisites to require verifying that no
internal or external clients consume the blog APIs before proceeding with `#519`,
and document how that verification will be performed. If any consumer is found,
replace the removal-only plan with a deprecation and migration plan.
- Around line 57-60: ADR-0022 must explicitly address the Agent contract
migration caused by removing blog_context. Update the ADR to state that
agent_career_summary.md, agent_self_pr.md, and test_agent.py must be updated
together with services/agent/context_builder.py, or retain blog_context until
those consumers are migrated; preserve prompt and test consistency throughout
the change.
