Ticket tool users 全体に ticket.language guidance が届くようにした。

実装概要:

• crates/ticket/src/tool.rs に shared ticket_tool_description(name, record_language) を追加し、configured ticket.language がある場合は Ticket tool description に durable Ticket record / Ticket tool body language guidance を追加するようにした。
• crates/pod/src/feature/builtin/ticket.rs の builtin Ticket feature ToolDeclaration descriptions でも同じ helper を使い、read-only Companion-style context と lifecycle/Ticket-role-style context の両方に guidance が届くようにした。
• guidance は worker.language / memory.language / ticket.language を区別し、protocol literals、file paths、commands、logs、identifiers、quoted external text は fidelity 優先で保持することを明記した。
• guidance は Ticket tool / capability surface で model-visible であり、hidden context injection や ticket_role launch prompt fragment ではない。
• Companion/read-only authority や mutating tool exposure は拡大していない。

Review / integration:

• Implementation commit: 92c4dee7 ticket: guide Ticket tool language universally
• Reviewer: yoi-reviewer-ticket-language-guidance が approve。
• Orchestrator merge commit: ec66cad8 merge: ticket language guidance for tool users
• Ticket completion commit: 2ba97b67 ticket: mark language guidance done

Validation:

• cargo test -p ticket ticket_record_language_guidance: pass
• cargo test -p pod ticket_language_guidance: pass
• cargo test -p client ticket_record_language_stays_out_of_first_run_text: pass
• cargo test -p ticket: pass, 68 tests
• cargo fmt --check: pass
• git diff --check HEAD~1..HEAD: pass
• ./result/bin/yoi ticket doctor: doctor: ok
• nix build .#yoi: pass

Known unrelated validation failure:

• cargo test -p pod still includes pre-existing failures in Pod orchestration guidance prompt assertion tests. These were verified on the Orchestrator branch before merge and reviewed as unrelated to this Ticket.

Cleanup:

• coder/reviewer Pods stopped。
• child worktree /home/hare/Projects/yoi/.worktree/ticket-language-guidance-all-tools removed。
• branch ticket/ticket-language-guidance-all-tools deleted。

Non-blocking risk:

• configured language guidance is appended to every Ticket tool description, including read-only tools. This repeats some prompt text, but it is the accepted universal capability-surface tradeoff for this Ticket.
