fix(mcp): escalate transient failures before asking for a restart (#6353)

* fix(mcp): escalate transient failures before asking for a restart

Give dropped connections and startup failures one bounded retry, then a
scripted handoff to the user. Point timeout recovery at a named request
field or REA_* setting instead of telling agents those limits are fixed.

* fix(process): stop unexpected command failures from recommending a retry

The catch can already have launched the target, and the projection stays
non-retryable. Tell the user to check the inputs and run doctor instead.

* fix(mcp): limit retries to safe calls and recommended settings

A dropped connection may already have changed the target, and a bad
catalog rejects the same startup every time. Retry only a repeatable
call, and change a setting only when the remediation recommends it.

* test(mcp): match recovery guidance across wrapped lines

Startup handoff capitalization and markdown wrapping still carry the
same sentences. Compare the prose with whitespace collapsed.
