* feat(agents): support `thinkingDefault: "adaptive"` for Anthropic models
Anthropic's Opus 4.6 and Sonnet 4.6 support adaptive thinking where the
model dynamically decides when and how much to think. This is now
Anthropic's recommended mode and `budget_tokens` is deprecated on these
models.
Add "adaptive" as a valid thinking level:
- Config: `agents.defaults.thinkingDefault: "adaptive"`
- CLI: `/think adaptive` or `/think auto`
- Pi SDK mapping: "adaptive" → "medium" effort at the pi-agent-core
layer, which the Anthropic provider translates to
`thinking.type: "adaptive"` with `output_config.effort: "medium"`
- Provider fallbacks: OpenRouter and Google map "adaptive" to their
respective "medium" equivalents
Closes#30880

* fix(secrets): normalize inline SecretRef token/key to tokenRef/keyRef in runtime snapshot
When auth-profiles.json uses an inline SecretRef as the token or key
value directly (e.g. `"token": {"source":"file",...}`), the resolved
plaintext was written back to disk on every updateAuthProfileStoreWithLock
call, overwriting the SecretRef.
Root cause: collectTokenProfileAssignment and collectApiKeyProfileAssignment
detected inline SecretRefs but did not promote them to the canonical
tokenRef/keyRef fields. saveAuthProfileStore only strips plaintext when
tokenRef/keyRef is set, so the inline case fell through and persisted
plaintext on every save.
Fix: when an inline SecretRef is detected and no explicit tokenRef/keyRef
exists, promote it to the canonical field and delete the inline form.
saveAuthProfileStore then correctly strips the resolved plaintext on write.
Fixes#29108
* fix test: cast inline SecretRef loadAuthStore mocks to AuthProfileStore
* fix(secrets): fix TypeScript type error in runtime test loadAuthStore lambda
* test(secrets): keep explicit keyRef precedence over inline key ref
