Add date filters to zypper search

[NeddM]

Fixes #575

Summary

Adds date-based filters to zypper search:

• --build-after YYYY-MM-DD
• --build-before YYYY-MM-DD
• --install-after YYYY-MM-DD
• --install-before YYYY-MM-DD

Validation

Built successfully in an openSUSE Tumbleweed container using:

cmake .. -DZYPP_PREFIX=/usr -DCMAKE_INSTALL_PREFIX=/usr -DLIB=lib64
make -j1

Manually validated:

./src/zypper search --help | grep -E "build-after|build-before|install-after|install-before"
./src/zypper search --build-after 01-01-2024 zypper
./src/zypper search --build-after 2024-01-01 zypper

Notes

This PR intentionally limits the initial scope to filtering results only. It does not add new table columns or XML output fields, keeping the change small and easier to review.

🤔

• How do you think about to support the filtering of time ranges?
• Can any time units be selected?

[NeddM]

Time ranges are currently supported by combining the after and before options, for example:

zypper search --build-after 2024-01-01 --build-before 2024-12-31 foo
zypper search --install-after 2024-01-01 --install-before 2024-12-31 --installed-only foo

For this first implementation I intentionally limited the accepted input to calendar dates in YYYY-MM-DD format. My idea was to keep the initial scope small and predictable, and avoid adding a more complex relative-time parser in the first PR.

Support for relative units such as days, weeks, or months could be added later if maintainers think that is useful, for example with options like --build-within 30d or similar.

How do you think about to experiment with an other filter parameter style? 🤔
filter_on installation between 2024-01-01 yesterday

[NeddM]

Thanks for the suggestion.

I think an expression-style filter syntax could be interesting, especially if zypper search gets more advanced filtering capabilities in the future.

For this PR, though, I would prefer to keep the interface based on explicit command-line options, for example:

zypper search --install-after 2024-01-01 --install-before 2024-12-31 foo

The reasons are:

• it follows the existing zypper search option style more closely
• it is easier to validate and document
• it keeps this PR small and focused on date filtering
• it avoids introducing a new mini-language/parser in the initial implementation

Relative dates such as yesterday could be useful, but I think they should probably be considered separately from this first version.
