Adds links from existing stack numbers in command output and TUIs to their GitHub stack pages, preserving compact labels and the existing PR-link fallback behavior.

Functionality and impact

• Links only the identifier (#N, or the existing numeric picker cell), not surrounding words or spaces.
• Preserves colored-terminal rendering and narrow layouts. Checkout discovery messages can contain links; confirmation questions remain plain text.
• Leaves confirmed missing or dissolved stacks unlinked, including stale local picker entries and stacks deleted during lookup.
• Adds no network requests or persisted URL fields. Existing navigation, JSON output, and path-only output are unchanged.

Key areas to review

• internal/config/config.go: shared OSC 8 formatting, sequence-safe underlining, and text versus compact fallbacks.
• cmd/checkout.go and cmd/link.go: failed versus empty listings, retained lookup errors, plain prompts, and missing-stack diagnostics.
• internal/tui/shared/header.go and internal/tui/submitview/screen.go: identifier-only styling and click bounds, including sidebar scrolling and closed-PR banners.
• internal/tui/checkoutview/model.go and internal/tui/mergeview/view.go: render complete hyperlink sequences without per-rune underlining or broken clipping.

Testing

Build, go vet ./..., and the full race-enabled suite (go run ./scripts/test -workers 4) pass. Focused regressions cover ANSI256 rendering, plain confirmation text, missing-stack races, and scroll/resize click targets. Existing command tests carry the lifecycle-output assertions rather than duplicating their workflow fixtures.

What changed in this PR

Adds links from stack-number references to their canonical GitHub pages, extending the CLI’s existing PR-link conventions across command output and terminal interfaces.

Changes:

• Add host-aware stack URLs, terminal hyperlinks, and copyable text fallbacks.
• Add clickable stack labels to view/submit and compact links to checkout/merge.
• Expand regression coverage and document link behavior and environment controls.
