fix: browse binary discovery broken for agents (v0.3.5) (#44)

* fix: replace find-browse with direct path in SKILL.md setup blocks

Agents were skipping the find-browse binary and guessing bin/browse
(wrong path). Now the setup block explicitly checks browse/dist/browse
with workspace-local priority, global fallback.

Also adds || true to update check to prevent misleading exit code 1.

Adds {{UPDATE_CHECK}} and {{BROWSE_SETUP}} template placeholders to
gen-skill-docs.ts so all skills share a single source of truth.

* refactor: convert qa/ and setup-browser-cookies/ to .tmpl templates

Replaces hardcoded update check and find-browse blocks with
{{UPDATE_CHECK}} and {{BROWSE_SETUP}} placeholders. Both skills
are now generated from templates via gen-skill-docs.

* test: add e2e and LLM eval tests for SKILL.md setup block

- 3 Agent SDK e2e tests: happy path, NEEDS_SETUP, non-git-repo
- LLM eval: setup block clarity + actionability >= 4
- New error pattern: 'no such file or directory.*browse'

These tests catch the exact failure mode where agents can't discover
the browse binary via SKILL.md instructions.

* chore: bump version and changelog (v0.3.5)
