MQ-01: the Anthropic adapter used a default http.Client, so a 3xx from the
configured endpoint was followed and the x-api-key header resent to the
redirect target; net/http strips only its own sensitive headers. Both
adapters now use a client whose CheckRedirect returns ErrUseLastResponse,
so a 3xx comes back as an llm.ProviderError and nothing is requested again.
The OpenAI-compatible adapter gets the same change: it forwards configured
extra headers (which may carry a credential and which net/http does not
treat as sensitive) across hosts, and net/http keeps Authorization on a
same-host https-to-http redirect.
MQ-02: a delay-seconds Retry-After too large for time.Duration overflowed
into a negative wait. retryAfter now caps the value at the most whole
seconds a time.Duration holds (also for values beyond int64) and the
response still maps to ErrRateLimited.
Tests: TestRedirectIsNotFollowed (302 to a second server, which must get
no request) and TestRateLimitedHugeRetryAfterIsCapped in both packages,
plus huge-number cases in TestRetryAfter.

The OpenAI adapter's redactedError had no GoString, so %#v printed its
fields, including the raw API key. Add GoString returning the redacted
text, matching the Anthropic adapter; redactedJoin inherits it.
Add TestRedactedErrorsFormatWithoutKey to both adapters, formatting
redactedError, redactedJoin and transportFailure with %v, %+v and %#v.
llm.ProviderError and llm.RateLimitedError keep no secret and are
already covered by TestTypedErrorsDoNotKeepSecret.

Add internal/ai/llm/anthropic, an llm.Provider over plain net/http:
- POST {base}/v1/messages and GET {base}/v1/models with x-api-key and
anthropic-version 2023-06-01. An empty key, a non-positive
Config.MaxTokens and a base URL that is not absolute http(s), or that
carries userinfo, a query or a fragment, are construction errors.
- System text goes in the top-level system field. A Request with a
Schema becomes one tool whose input_schema is the schema, forced by
tool_choice; Response.JSON is that tool's input. Otherwise the text
blocks are Response.Text. Usage and stop_reason are parsed.
- ListModels follows has_more/after_id pages; Verify fetches one page
with limit=1.
- 401/403 map to ErrAuth, 429 and 529 to ErrRateLimited with
Retry-After, 408 and deadlines to ErrTimeout, other statuses to
ErrProvider with a redacted excerpt.
- Errors carry the OpenAI adapter's redaction chain, so no Error(),
Unwrap layer, errors.As target or %#v output holds the key.
Contract tests replay sanitized fixtures adapted from Anthropic's public
Messages API docs over httptest, covering tool-forced JSON, text, each
error mapping and key redaction with the keys x-api-key, anthropic,
HTTP, rate, a one-letter key and a URL-escaped key.

Feature 03 made the OIDC variables required, so the Feature 04 boot tests'
loadConfig helper now sets them alongside the secret key file.
