Model-facing tool-call budgets were tangled into each capability's schema (bash timeoutMs, web_fetch timeout_ms) with no shared home. Add a tools/execute around-dispatch waterfall to dsh-tools whose base next() is the dispatch-with-normalization thunk, and a new @deepseek-ai/dsh-timeout-policy plugin (packages/timeout/) that arms a per-tool deadline on exec.signal and returns a structured TOOL_TIMEOUT when it wins. Migrate web_fetch (drop the model-facing timeout_ms) and web_search onto it; the fetch provider keeps its timeout only as a resource backstop for direct callers. bash and hook command execution keep BASH_TIMEOUT unchanged. Named the plugin timeout-policy (not the RFC's tool-timeout) so it does not trip the gen-tool-catalog packages/*/tool-* completeness guard, and replace exec.signal by in-place mutation before next() since cordis waterfall next() ignores passed arguments. RFC moved to implemented/ recording both deviations.

timeout/ — tool-call timeout policy
The tool-call timeout policy plugin. A single product package: it is a deployment-policy consumer of the tools/execute around-dispatch seam (owned by dsh-tools) and the pure dsh-timeout library — not a swappable capability with an interface/implementation split, so it needs no seam trio.

timeout-policy/ |
A tools/execute wrapper: for each configured tool it arms a per-call deadline on exec.signal and returns a structured TOOL_TIMEOUT result when that deadline wins |
(registers a tools/execute listener; injects nothing) |
Timeout is split across three layers: dsh-timeout owns the pure timing/classification primitive (deadline/timeoutOf), each capability owns termination (bash kills its process group, the fetch provider tears down its socket), and this package owns the model-facing tool-call budget as deployment policy — no model-facing timeout argument, no global default. It is the middleware the timeout-library RFC foresaw. bash and hook command execution keep their own BASH_TIMEOUT backend timeout and do not route through this policy.
