content: add 3 Ethiopia canons (visa, safety, medical); re-verify 3 aging canons

[dbwls99706]

Gap filled

Ethiopia (et) was tied with Egypt for the most underserved supported country: only 4 of 12 country-scoped domains covered (banking, culture, emergency, medical), with visa, legal/safety, communication, food-safety, policy, disaster, and mental-health all empty. This PR adds 3 new canons across 3 previously-empty domains.

Canons added

• visa/visa-extension-in-person-addis-only/et — Ethiopia's e-visa cannot be extended online or at a regional office. Both the UK FCDO and Canada's official travel advisory state the extension must be filed in person, before expiry, at the Immigration and Citizenship Service (ICS) Head Office in Addis Ababa. Overstay fines accrue daily and travelers cannot leave the country until they're paid in full.
• safety/photographing-government-military/et — Canada's travel advisory lists roads, bridges, dams, and airfields alongside military installations and government buildings as strictly prohibited to photograph — not just obviously sensitive sites. Separately, the UK FCDO warns there are no published drone guidelines and drones may be confiscated at the border; a permit from the Ethiopian Civil Aviation Authority (ECAA) and the Information Network and Security Agency (INSA) is required first. ECAA's own site corroborates the regulatory gap — its RPAS (drone) rules were still at draft-validation stage as of its own workshop announcement, years into the process.
• medical/addis-ababa-malaria-altitude-dispute/et — The US CDC and the UK's national travel-health authorities give opposite malaria guidance for Addis Ababa specifically, because the city's elevation (~2,350–2,410 m depending on source) sits between their two different cutoffs: CDC uses 2,500 m (risk area, includes Addis Ababa), UK NaTHNaC/FCDO uses 2,000 m (no risk in Addis Ababa). A traveler or AI agent that checks only one authority gets a confident but contradictory answer.

Sources used

• UK Foreign, Commonwealth & Development Office — Ethiopia travel advice (entry requirements, local laws and customs, health)
• Canada's official travel advisory (travel.gc.ca/destinations/ethiopia)
• Ethiopia's Immigration and Citizenship Services (ics.gov.et)
• Ethiopian Civil Aviation Authority (ecaa.gov.et)
• US CDC Travelers' Health — Ethiopia destination page
• UK NaTHNaC / TravelHealthPro — Ethiopia country page

All dead ends cite at least 2 primary/government sources; no Reddit or blog content was used as a sole source for any claim.

Aging-canon re-verification

Per the recurring re-verification cycle, checked the oldest untouched last_confirmed canons and refreshed dates where content and sources still hold:

• rust/e0700-async-closure-lifetime/rust1-linux (was 2026-02-01) — Rust book/error-codes sources still resolve and match the documented move/named-lifetime/Pin<Box<dyn Future>> guidance.
• typescript/ts5023-unknown-compiler-option/ts5-linux (was 2026-02-01) — TypeScript handbook, tsconfig reference, and tsconfig/bases GitHub repo all still resolve and match.
• aws/access-denied-exception/awscli2-linux (was 2026-02-11) — AWS IAM best-practices, Access Analyzer, and policy-creation docs all still resolve at the same anchors and match the documented guidance.

No content changes were needed for any of the three — only last_confirmed / last_updated / last_verification were bumped to today.

Validation

• ruff check generator/ tests/ — passed
• python -m pytest tests/ -q — 337 passed
• python -m generator.validate --data-only — passed (0 stale, only expected aging warnings)
• python -m generator.build_site — 2,486 pages generated
• python -m generator.validate --site-only — passed
