* fix(kube): improve error handling in table column lookup

Add error handling for missing columns in Table.find_indexes method.
Previously the function would silently ignore missing columns,
now it returns a helpful error message with available columns.
This makes debugging easier by providing context when columns
are missing.

* feat(kube): support customizable columns for pod resources

Add support for configurable columns in pod display:
- Define POD_DEFAULT_COLUMNS constant with standard columns
- Add columns field to PodConfig struct
- Update pod table generation to use configured columns
- Maintain namespace column logic when viewing multiple namespaces
- Adjust color highlighting to work with customized column layout

* feat: add customizable pod columns via command line

Add ability to customize which columns are displayed in the pod table
via the new --pod-columns flag. Users can specify columns as a
comma-separated list (e.g. "name,status,age") or use "full" to show
all available columns. Name column is always included for reference.

* feat(zsh): add pod columns customization completion

Add ZSH completion support for the new --pod-columns option which
allows users to customize which columns are displayed in pod view.
The completion provides all available column options, supports
comma-separated values, and includes the 'full' option to display all
columns. This enhancement improves the shell experience when using
kubetui's pod column customization feature.

* chore(bash): update vim modeline settings in shell scripts

Change the vim modeline settings in bash completion script to match
project conventions. Set noet (no expandtab) to maintain tabs in shell
scripts.

* feat(bash): add pod-columns option to bash completion

Add support for --pod-columns option in bash completion script.
This enables auto-completion for column values when configuring
pod display columns in kubetui.

* feat(error): add error logging for panic information

Add logger macro call to panic hook to ensure panic information is
properly logged. This helps with debugging by preserving error context
in log files even when panics occur.

* feat(args): validate 'full' column can't be combined with others

When specifying pod columns, the 'full' option should be used alone as it
includes all available columns. This change adds validation to prevent
users from combining 'full' with other column names, providing a clear
error message to guide proper usage.

Tests have been added to verify both the error case and the valid usage
of the 'full' option.

* feat(args): filter empty elements in pod columns input

Add filtering logic to remove empty elements when parsing pod columns.
This enhancement provides better UX by allowing comma-separated input with
empty elements (like "ready,,status") to be processed correctly instead
of causing errors.

Added tests to verify both valid cases with empty elements and cases
where only empty elements are provided.
