feat(hire): sharpen positioning copy per updated studio draft

[Koopa0]

Summary

Owner-approved copy revision of /hire, synced verbatim from the updated source draft. Three changes:

• Fail-closed orchestration bullet sharpened. It now opens with the failure modes agent buyers recognize — a tool call with hallucinated arguments, a retry that fires the same side effect twice, a delegated agent holding permissions it should never have — "designed away, not prompted away." The other two bullets are unchanged (minimal variant, deliberately).
• Language positioning line after the Go section: Go first, Rust second — for the smaller correctness-critical pieces (parsers, CLIs, verification tools), held to the same bar. Capability statement only; deliberately no project link — the public Rust receipt waits for a project intended for open source.
• Frontend positioning line: names the supporting capability (this site, public face and admin cockpit, is my Angular end to end) while keeping the backend pitch primary. Only Angular is named — the live site is the receipt; other frontend work stays off-page.

Test Plan

• npx tsc --noEmit — clean
• npx ng lint — all files pass
• npx ng test — 617/617 (hire.spec now 7 cases; new test pins the three new copy fragments)
• npx ng build — prerender verified: all new copy fragments present in dist/.../hire/index.html
• Verbatim fidelity script: all 18 prose units of the updated draft present in the page, unchanged

Out of scope

No layout, route, or footer changes. Unrelated working-tree docs changes untouched.
