🚦 feat: Configurable Circuit Breakers for Runaway Streamed Tool Args (#14613)
* 🚦 feat: Configurable Circuit Breakers for Runaway Streamed Tool Args

* docs: forewarn create_file about the streamed tool-argument limit

The breaker failing a near-limit write should not be the model's first
exposure to the bound. Both create_file variants now state the default
64 KB per-call limit and the incremental pattern (create the first
section, extend with edit_file) in the tool description and the content
parameter description.

* fix: keep skill create_file description under the provider advisory cap

The limit-guidance paragraph pushed the skill-aware description to 1169
chars, past the 1024-char advisory bound where providers may truncate.
The skill variant now carries the guidance only in its content parameter
description, which sits closest to the generated payload and is not at
truncation risk; the shorter code-sandbox variant keeps the full
paragraph.

* 🚦 feat: per-tool streamed-arg limits with a create_file default

Thirty days of production data show create_file is the only tool class
with legitimate near-limit arguments (p99 80.6 KiB; every other tool
p99 under 10 KiB). Rather than loosening the global 64 KiB cap for all
tools, the yaml gains maxToolCallArgBytesByTool (per-tool overrides,
keyed by model-facing tool name, 0 disables that tool's guard) and
LibreChat ships { create_file: 131072 } by default; yaml entries merge
over and can replace it. Pairs with maxToolCallArgBytesByTool support
in the agents SDK and stays inert until the dependency bump.

* test: pass per-tool spec configs as plain Partial literals

The as-TAgentsEndpoint casts fail TS2352 for object-valued fields:
comparability does not grant nested literals the implicit index
signature that plain assignability does, so casts carrying
maxToolCallArgBytesByTool never sufficiently overlap. The mapper
already accepts Partial<TAgentsEndpoint>, so the new cases pass
uncast literals instead.

* chore(deps): bump @librechat/agents to 3.3.12
