chore: release v4.5.0-rc.3 (#3763)

## Summary
1 improvement, 2 bug fixes.

## Improvements
- Retry `TASK_MIDDLEWARE_ERROR` under the task's retry policy instead of
failing the run on the first attempt. The error was already classified
as retryable by `shouldRetryError`, but `shouldLookupRetrySettings` did
not include it, so the retry flow fell through to `fail_run`. Fixes
#3231. ([#3676](#3676))

## Bug fixes
- Fix `TypeError` in `unflattenAttributes` when the input attribute map
contains conflicting dotted key paths (e.g. both `a.b` set to a scalar
and `a.b.c` set to a value). The path-walk loop now applies
last-write-wins when a prior key wrote a primitive, null, or array at an
intermediate slot, matching the existing precedent in
`AttributeFlattener.addAttribute`. Callers no longer crash when handed
malformed external attribute inputs.
([#3762](#3762))
- Fix external trace context leaking across runs on warm-started workers
with `processKeepAlive` enabled. Every subsequent run's attempt span was
being exported with the first run's `traceId` and `parentSpanId`,
breaking causal-chain navigation in external APM tools. Runs without an
external trace context are unaffected.

`main` is currently in **pre mode** so this branch has prereleases
rather than normal releases. If you want to exit prereleases, run
