Fixes #1059.

Adds user-guide guidance for Hamcrest matchers in expect: and then: blocks, plus explicit assert that(...) usage. Includes import guidance, a closeTo example, and a cross-reference to mock argument constraints. Adds executable documentation specs for the examples.

Validation:

• Focused HamcrestMatchersDocSpec: 3 tests passed.
• Asciidoctor documentation build passed.
• Full Gradle build passed from a no-space temporary worktree (80 actionable tasks).

AI assistance: drafted with Codex (GPT-6); I reviewed the APIs, examples, and build results.

Walkthrough

The Spock Primer now documents Hamcrest matcher use in conditions, explicit assertions, and mock argument constraints. A new specification demonstrates matcher use in expect: and then: blocks and in a setup assertion. An anchor identifies the Hamcrest Constraint subsection.

_{A rabbit checks a matcher near,
Then writes its uses, plain and clear.
In expect: and then: it tests,
A setup check completes the quests.
A guide gains one anchor, neat and bright,
And hops away into the night.}

sentence on its own AsciiDoc line, including the sentence about `closeTo` and
