chore(api): AX compliance sweep — banned imports, naming, test coverage 
Replace fmt/errors/strings/encoding/json/os/os/exec/path/filepath with
core primitives; rename abbreviated variables; add Ugly test variants to
all test files; rename integration tests to TestFilename_Function_{Good,Bad,Ugly}.

## 8. Response Caching
`WithCacheLimits(ttl, maxEntries, maxBytes)` installs a URL-keyed in-memory response cache scoped to GET requests:
```go
engine, _ := api.New(api.WithCacheLimits(5*time.Minute, 100, 10<<20))
```
`WithCache(ttl)` installs a URL-keyed in-memory response cache scoped to GET requests:
- Only successful 2xx responses are cached.
- Non-GET methods pass through uncached.
- Cached responses are served with an `X-Cache: HIT` header.
- Expired entries are evicted lazily on the next access for the same key.
- The cache is not shared across `Engine` instances.
- `WithCache(ttl)` remains available as a compatibility wrapper for callers that do not need to spell out the bounds.
- Passing non-positive values to `WithCacheLimits` leaves that limit unbounded.
- There is no size limit on the cache.
The implementation uses a `cacheWriter` that wraps `gin.ResponseWriter` to intercept and
capture the response body and status code for storage.

## Known Limitations
### 1. Cache remains in-memory
### 1. Cache has no size limit
`WithCache(ttl, maxEntries, maxBytes)` can now bound the cache by entry count and approximate
payload size, but it still stores responses in memory. Workloads with very large cached bodies
or a long-lived process will still consume RAM, so a disk-backed cache would be the next step if
that becomes a concern.
`WithCache(ttl)` stores all successful GET responses in memory with no maximum entry count or
total size bound. For a server receiving requests to many distinct URLs, the cache will grow
without bound. A LRU eviction policy or a configurable maximum is the natural next step.
### 2. SDK codegen requires an external binary
