docs: pattern break archaeology — WHY (not just WHAT) is impure
Git blame + commit messages reveal four categories:
1. Ship behavior, fix plumbing later (time pressure)
2. Better tooling exposed limitations (observability)
3. Removal cost > carrying cost (zero-interest debt)
4. Context needs different patterns (not actually a break)
Specific findings:
- CockroachDB Handle: introduced for profiling, not correctness
- Stale 22.2 TODO: struct field costs 0, removal touches many files
- Prometheus globals: startup constants read in hot path = correct call
- AppenderV2: unifies 4 type-asserted interfaces into 1
- Ecto zero TODOs: version-gated, cleaned on version bumps by José
