`mvn verify` (the canonical goal that produces target/failsafe-reports/)
previously fell through to Passthrough — no filtering, no XML enrichment
— even though the failsafe parser was already implemented for run_test.

- New MvnCommands::Verify variant; dispatch_mvn routes to run_verify.
- Extract run_test body to private run_tests_like(binary, goal, ...);
  both run_test and run_verify wrap it. Shared filter + enrichment.
- Parameterize filter_mvn_test summary prefix via filter_mvn_tests_with_goal
  (goal in {"test", "verify"}). Public wrappers filter_mvn_test /
  filter_mvn_verify preserve existing call sites.
- Generalize enrich_with_reports zero-tests detection + error message
  (ends_with(": no tests run"), goal extracted from summary prefix).
- Discover rules: add `verify` to mvn and mvnd patterns.
- Snapshot + prefix-assertion tests for verify path; goal-awareness test
  for enrichment's zero-tests branch.

Addresses P2 rtk-ai#7 from the review of sibling PR rtk-ai#782.

Multi-module compile output was dominated by the `Reactor Build Order:` block
and per-module `Reactor Summary` status lines (~40 redundant tokens on a
green 5-module build), and javac `[ERROR] <path>:[line,col]` locations were
emitted twice — inline during compilation and again in the trailing help
block — nearly doubling the failure-path output.

Changes in filter_mvn_compile:
- Skip `Reactor Build Order:` block entirely (redundant with per-module
  Building headers that are already stripped).
- Collapse Reactor Summary: emit a compact `Reactor: N modules — M SUCCESS,
  K FAILURE (name, ...)` line only when something failed; all-green reactors
  rely on the surviving `BUILD SUCCESS` line.
- Dedup `[ERROR] <path>:[line,col]` occurrences by (path, line, col). When
  a duplicate fires, swallow the indented `[ERROR] symbol:/location:/
  required:/found:/reason:` context lines that mirror an earlier javac
  explanation emitted without the `[ERROR]` prefix.

Also: broaden `deprecated` check to `deprecat` (catches both `deprecated`
and `deprecation` variants); strip `/pom.xml` path references (previously
only literal `from pom.xml` matched); drop the Help-footer line `For more
information about the errors...` which wasn't in the boilerplate list.

Savings on fixtures adapted from rtk-ai#782 (attribution in filenames):

  mvn_pr782_compile_success_raw  74.6% → 97.8%  (+23pp)
  mvn_pr782_compile_fail_raw     49.1% → 79.7%  (+31pp)
  mvn_pr782_test_pass_raw        98.7% → 98.7%  (unchanged, correct)
  mvn_pr782_test_fail_raw        93.4% → 93.4%  (unchanged, correct)

Four new regression tests validate multi-module accumulation (20 tests
across 6 modules must not report only the first module's count), failure
enumeration uniqueness, reactor collapse, and javac error dedup.
