* feat(interactions): continue requires_continuation long decodes with continuation_token hops
A foreground Interactions request stops at Google's per-hop output cap with
status requires_continuation and a continuation_token. litellm now re-posts the
request with previous_interaction_id and continuation_token until the status
moves on, merging the hops into one interaction (last id, every hop's steps,
summed usage with initial_input_tokens from hop 1), for non-streaming and
streaming calls. continuation_token is accepted as a request param, and
requires_continuation is a known status for billing.
* refactor(gemini interactions): validate streaming chunks with model_validate
* fix(interactions): keep the held completion across stream hops, stop on a repeated continuation_token, follow the spec redirect
* fix(interactions): add grounding_tool_count per tool type, stop on any seen continuation_token, keep streaming past a [DONE] frame when a hop is pending
* ci(interactions): point the spec canary at aistudio.google.com, where Google moved the Interactions OpenAPI spec
* test(interactions): scripted Google ends each long decode hop with a [DONE] frame
* refactor(interactions): pass requires_continuation and continuation_token through instead of looping hops in the proxy
The caller drives the continuation, the same as against Google directly. /interactions accepts continuation_token in place of input so a resume request needs no input.
* test(proxy): assert the accepted /interactions bodies pass the required-param check
* fix(proxy): keep the router default fallback for input on /interactions, continuation_token stands in for it

* test(interactions): assert the live status enum is parsable instead of pinning it
* test(interactions): read the spec from a vendored snapshot and canary the live one daily
* test(interactions): run the canary on PRs touching its inputs, file an issue on a red run, pin the regenerate command
* test(interactions): take the live spec URL as a pytest option, assert its source, split the canary's tracking-issue job
* test(interactions): file the canary issue whenever its compliance step did not pass, match the issue title exactly, cover UrlContextResult
