Till JS 4b8fede7fc fix(mana-llm): surface Gemini finish_reason errors instead of returning ""
The google provider called response.text after a chat completion and
passed the resulting string downstream unchanged. When Gemini's content
filter, recitation guard, or max_tokens ceiling fired, response.text
quietly returned "" — which the planner then reported as "no JSON block
found", masking the real cause. Empirically this failed in 45 ms on a
simple Quiz mission.

Introduces providers/errors.py with a small ProviderError hierarchy
(Blocked / Truncated / Auth / RateLimit / Capability). google.py now
inspects response.candidates[0].finish_reason and raises the matching
structured error; the non-streaming path maps it to 422/502/429 via a
new except-branch in main.py, and the streaming path surfaces the kind
as the SSE error type. Capability is wired but not yet used — it lands
with the tool-schema passthrough in the next commit.
