plans/exit.md: record final status; defer phase 5; convert stragglers (#2207)
Phase-5 wrap-up for plans/exit.md. The DSL-runtime cluster (pkg/dsl/cst:
hofs.go, udf.go, evaluable.go) is deferred rather than converted: 58
regression cases pin the current loud-failure behavior (exact stderr plus
exit 1), and the planned error-Mlrval mechanism would make HOF/UDF misuse
fail silently as bare '(error)' with exit 0 -- a debugging-UX regression.
The alternative (typed panic recovered at the Execute* boundaries) preserves
behavior but introduces panic/recover to a codebase that has none. The
decision belongs with the issue-440 strict-mode design, where the
fatal-vs-data error taxonomy gets decided anyway; plans/exit.md now records
the rationale, the phase-by-phase status (#2198, #2202, #2204, #2205), and
the final intentional keep-list.

Also converted here, since they're squarely in prior phases' patterns rather
than the deferred expression-depth cluster:

- RootNode.ProcessEndOfStream (a phase-3 leftover on the put/filter
  Transform path) returns an error instead of printing-and-exiting on
  end-of-stream close failures; first error returned, any others printed at
  the site.
- The three CompileMillerRegexOrDie calls in option_parse.go (inside
  error-returning parser closures since phase 2) use CompileMillerRegex and
  return the error; 'mlr --ifs-regex (' output and exit code are unchanged.

All 4779 regression cases pass; make lint 0 issues.
