test: cover Filter #-prefixed tag keys in cache manager loadEvents

[nogringo]

Summary by CodeRabbit

• Improvements
  • Tag keys are normalized without a leading # when used in filters, and serialized with # where required.
  • Adding extra tags in the request command now replaces existing values for matching keys.
• Tests
  • Added coverage confirming tag-key matching is case-sensitive: A and a match only their respective tags.

📝 Walkthrough

Walkthrough

Filter now stores tag keys without the NIP-01 # prefix and restores the prefix during serialization. The request CLI merges parsed extra tags by replacing entries with matching keys. Tests cover normalized keys and case-sensitive cache tag queries.

Changes

Filter Tag Key Handling

Layer / File(s)	Summary
Normalize filter tag keys packages/ndk/lib/domain_layer/entities/filter.dart	The constructor, setter, parser, and tag methods normalize keys to bare names. Serialization adds # to arbitrary tag keys.
Merge CLI extra tags packages/ndk/lib/src/cli/req_cli_command.dart	The request command merges parsed extra tags into the filter map. Parsed entries replace existing values for matching keys.
Validate tag key behavior packages/ndk/test/entities/filter_test.dart, packages/ndk_cache_manager_test_suite/lib/src/cache_manager_test_suite_event.dart	Filter tests check bare keys after construction, assignment, and parsing. Cache tests check that queries for A and a return events tagged with the matching key.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to 4b0c5

Callers that write prefixed keys directly into a filter’s tag map may no longer retrieve those tags by bare key. This is a bounded compatibility risk to address or explicitly accept before merging.

Before / after behavior

• observed — Modified behavior in packages/ndk_cache_manager_test_suite/lib/src/cache_manager_test_suite_event.dart: Adds coverage for querying events with Filter’s #p-prefixed tag criteria: with kind 1059 and recipient_pubkey selected, only the matching event ID is expected.

@nogringo opted for the solution to store the tags without the # prefix on the filter, can discuss if this is the right solution or if we adjust the objectbox impl.

Keep direct tag-map writes consistent with bare-key lookup.

If a caller writes filter.tags!['#p'] = values, the getter exposes _tags and bypasses the setter. getTag('p') then returns null, even though toMap() serializes the entry as #p. Normalize writes through the public map, or prevent direct mutation so callers must use setTag or the setter.
