fix(ci): drop invalid timeout-minutes from reusable-workflow calls (parse-dead) (#44)

## What

One or more jobs set a job-level `timeout-minutes:` on a job that calls
a reusable workflow via `uses:`. GitHub does not permit that key on a
`workflow_call` job, so it **rejected the file at parse time** — the
workflow failed instantly (`0s`) on every push and never ran a single
job.

## Fix

Remove the invalid caller-side `timeout-minutes:`. The standards
`*-reusable.yml` workflows already declare `timeout-minutes` on every
internal job, so the caller key was redundant as well as invalid.

## Verification

`actionlint` (real tool): no `timeout-minutes is not available` findings
remain.

## Context

Estate-wide shared-fate CI defect across 84 repos. Reference fix:
hyperpolymath/gitbot-fleet#374.
