Document /goal, /recap, and terminal display modes

[malston]

Adds three sections to the Workflow Patterns guide, all verified against the official Claude Code docs and changelog.

Sections added (content/guides/workflow-patterns.md)

• Goal-Driven Sessions with /goal (Document the /goal autonomous completion command #40) -- set a completion condition and Claude works across turns until a fast-model evaluator confirms it. Covers set/check/clear, writing effective conditions, the Stop-hook implementation, requirements, and resume behavior. Sourced from code.claude.com/docs/en/goal and changelog 2.1.139.
• Session Recap with /recap (Document session recap (/recap) #54) -- one-line recap on return, with the /config toggle, awaySummaryEnabled setting, and CLAUDE_CODE_ENABLE_AWAY_SUMMARY precedence. Sourced from interactive-mode#session-recap, settings, env-vars, and changelog 2.1.108/2.1.110.
• Terminal Display Modes (Document /tui fullscreen rendering mode and /focus #53) -- /tui fullscreen vs default, /focus condensed view, Ctrl+O verbose transcript, plus the tui / autoScrollEnabled settings and CLAUDE_CODE_DISABLE_ALTERNATE_SCREEN. Sourced from fullscreen, settings, interactive-mode, and changelog 2.1.110/2.1.132.

TOC updated; Hugo builds clean at 103 pages. No em dashes / banned filler / contrastive reframes in the new content.

Pull request overview

This PR extends the Hugo wiki’s Workflow Patterns guide with new user-facing documentation for Claude Code’s /goal, /recap, and terminal UI display modes, aligning the guide with the referenced product docs/changelog items.

Changes:

• Adds a Session Recap section documenting /recap behavior and configuration/precedence controls.
• Adds a Goal-Driven Sessions with /goal section describing evaluator-driven completion loops, constraints, and resume/headless behavior.
• Adds a Terminal Display Modes section documenting /tui, /focus, transcript viewing, and related settings/environment variables; updates the page TOC accordingly.

Checked this against the authoritative source before changing anything. The official Claude Code docs (https://code.claude.com/docs/en/interactive-mode, "Session recap" section) state verbatim:

Session recap is on by default for every plan and provider. The recap is always skipped in non-interactive mode.

That matches line 422 word-for-word, so the guide is accurate as written and documents current shipped behavior. Any telemetry-disabled-only condition implied by Issue #54 was either historical or doesn't reflect the current default. Leaving the line unchanged.
