Step 2 of plan.md (Spor B B3 pipeline run). Wires the --regex/-r flag
into main(): when set, compileRegex(pattern) is used and the count is
text.match(re).length. Invalid regex exits 2 via the existing fail()
helper. JSON output now includes flags.regex so consumers can tell the
mode apart. Baseline tests remain green; -i/--ignore-case has no effect
when --regex is set (out of brief scope).
Verify covered: SC #1 (any position), SC #2 (-r short form), SC #3
(regex semantics differ), SC #4 (invalid exits 2), SC #5 (JSON regex),
SC #6 (byte-identical baseline).

Step 1 of plan.md (Spor B B3 pipeline run). Adds the new --regex / -r
flag to parseArgs and a compileRegex(pattern) helper. The flag is
parsed but main() does not yet branch on it (wired in step 2). All
10 baseline tests remain green.

Adds the runnable counterpart to examples/01-add-verbose-flag (which is
artifacts-only). The fixture is the measurement target for Spor B's
end-to-end pipeline run (B3) and Spor C's cache-prefix experiment.
Baseline:
- tally.mjs (80 lines, hand-rolled argv parser, zero deps)
- 3 flags: --json, -i/--ignore-case, --lines + --help
- Exit codes: 0 success, 1 file error, 2 invalid argv
- 10 node:test cases, all green (~2.2s wall-clock)
- Deterministic fixtures: sample.txt (foo×7, Foo×1, regex fo+×9) +
poem.txt (--lines vs total distinction)
- REGENERATED.md skeleton (B3 fills the pipeline walk-through)
Brief preconditions verified:
- grep -c 'foo' sample.txt = 4 (>= 1)
- regex /fo+/g count = 9 (> grep count)
- Brief assumptions for B3 SC #1, #3 hold
This is the first runnable example in plugins/ultraplan-local/examples/.
Next: B3 runs /ultraresearch-local + /ultraplan-local + /ultraexecute-local
against the brief to add --regex/-r, then verifies all 10 Success Criteria.
