refactor(search): rename --after/--updated-after to --since/--updated-since

The --since naming is more intuitive (matches git log --since) and
consistent with the list commands which already use --since. Renames
the CLI flags, SearchCliFilters fields, SearchFilters fields,
autocorrect registry, and robot-docs manifest. No behavioral change.

Affected paths:
- cli/mod.rs: SearchArgs field + clap attribute rename
- cli/commands/search.rs: SearchCliFilters + run_search plumbing
- search/filters.rs: SearchFilters struct + apply_filters logic
- main.rs: handle_search + robot-docs JSON
- cli/autocorrect.rs: COMMAND_FLAGS entry for search
