Jinwoo Hong 3e4fd4a7af Shorten orchestration skill description under the Agent Skills 1024-char limit (#18683)
* Shorten orchestration skill description under the Agent Skills 1024-char limit

The folded description was 1038 chars, so spec-conforming installers such
as SkillStar rejected the bundled orchestration skill. Drop the two clauses
already covered elsewhere in the same description: "decomposing work across
agents" (implied by "structured multi-agent coordination") and "automation
of the browser embedded inside Orca" (restated by the locked `orca-cli`
embedded-pages sentence). Every routing trigger asserted by
orchestration-skill-guidance.test.mjs, the orca-cli handoff boundary, and
the Computer Use boundary are unchanged. Result: 958 chars.

Add config/scripts/skill-description-length.test.mjs, which parses every
skills/*/SKILL.md frontmatter with `yaml` and fails on an empty or >1024
char description, so the regression cannot return. orca-cli sits at 1015
and is left as is.

Fixes #17935

* Keep the embedded browser in the orchestration description's orca-cli routing

Restores the word "browser" in the orca-cli sentence ("and the Orca embedded
browser") so agents scanning for it still route embedded-browser control to
orca-cli. Description is 985 chars, 39 under the spec limit.
