feat: dynamically adjust page size based on terminal height

[ZaidQtaish]

Description

The page size was hardcoded to 15 repos per page regardless of terminal size. This updates resizeTable() to dynamically set pageSize based on available terminal height, so larger terminals show more repos and smaller ones show fewer. Minimum page size is capped at 5.

Fixes #17

Pull request overview

This PR updates the TUI pagination behavior so the number of repositories shown per page adapts to the available terminal height, instead of using a fixed default (15), and tweaks the docs navbar GitHub link styling.

Changes:

• Update resizeTable() to set pageSize based on the computed table height (with a minimum of 5).
• Trigger a table refresh after resizing so the new pageSize takes effect immediately.
• Adjust the docs navbar GitHub link styling to use a flex layout.

Calling m.updateTable() from resizeTable() means every tea.WindowSizeMsg will re-run applyFilter() and sortRepos() (O(n log n)) even though only the current page slice needs to change. Consider updating just the visible rows for the current page (and only re-sorting when the underlying repo list / filter / sort mode changes) to avoid unnecessary work during continuous resize events.

Suggested change

	m.pageSize = h // Update page size based on new height
	m.updateTable() // Refresh table to apply new page size
	// Only refresh the table when the effective page size actually changes
	if h != m.pageSize {
	m.pageSize = h // Update page size based on new height
	m.updateTable() // Refresh table to apply new page size
	}

pageSize can change on resize without adjusting currentPage. If pageSize increases, currentPage*m.pageSize may become out of range, and getCurrentPageRepos() will silently fall back to showing the first page while currentPage remains unchanged, leading to inconsistent pagination state (and incorrect “Page X of Y” behavior). After changing pageSize, clamp currentPage to [0, totalPages-1] (or reset it) before refreshing rows.

Suggested change

	m.pageSize = h // Update page size based on new height
	m.updateTable() // Refresh table to apply new page size
	m.pageSize = h // Update page size based on new height
	// Clamp currentPage to the valid range for the new page size to keep pagination consistent
	totalRows := len(m.table.Rows())
	if totalRows == 0 {
	m.currentPage = 0
	} else {
	totalPages := (totalRows + m.pageSize - 1) / m.pageSize
	if totalPages < 1 {
	totalPages = 1
	}
	if m.currentPage < 0 {
	m.currentPage = 0
	} else if m.currentPage >= totalPages {
	m.currentPage = totalPages - 1
	}
	}
	m.updateTable() // Refresh table to apply new page size and current page

This change makes pageSize effectively ignore the configured cfg.PageSize (the initial pageSize from config will be overwritten on the first window-size event). If pageSize is meant to remain user-configurable, consider only applying the dynamic sizing when the config value is unset/default, or treating the config value as a hard override / max.

Suggested change

	// Ensure page size is at least 5 to avoid too small pages
	if h < 5 {
	h = 5
	}
	m.pageSize = h // Update page size based on new height
	// Compute a dynamic page size based on height, with a minimum of 5
	dynamicPageSize := h
	if dynamicPageSize < 5 {
	dynamicPageSize = 5
	}
	// If a positive PageSize is configured, respect it; otherwise use the dynamic size
	if m.cfg != nil && m.cfg.PageSize > 0 {
	m.pageSize = m.cfg.PageSize
	} else {
	m.pageSize = dynamicPageSize
	}

Will review the code, and test it.
