Drops six per-function lodash.* packages in favor of a single
es-toolkit dependency, using the lodash-compatible /compat surface so
behavior matches the existing tests — including the non-Latin
subject-case regressions added after the kasi revert (#4621).

Replacements:

- lodash.camelcase / kebabcase / snakecase / startcase / upperfirst →
  es-toolkit/compat in @commitlint/ensure (case helpers)
- lodash.mergewith → es-toolkit/compat:
  - mergeWith (with customizer) in @commitlint/resolve-extends
  - merge (no customizer) in @commitlint/load,
    @commitlint/config-patternplate, and the cli test helper

es-toolkit/compat's mergeWith always treats the last positional
argument as the customizer, unlike lodash's createAssigner which
detects function-typed customizers. Call sites that passed objects (no
customizer) are switched to es-toolkit's variadic merge to preserve
behavior.

Test results: 1185/1185 tests across 90 files pass, including the
Cyrillic / Chinese / Arabic / Hebrew / mixed-script subject-case cases
that broke under kasi.
