refactor: remove unused exports from internal modules (#2465)

* refactor: remove unused exports from internal modules

Remove export keyword from symbols that are never imported outside
their defining module (including tests). This reduces the public API
surface and clarifies which symbols are internal implementation details.

Symbols de-exported:
- domain-patterns.ts: DomainProtocol, ParsedDomain, ParsedDomainList
- cli.ts: AgentImageResult, ApiProxyValidationResult,
  FlagValidationResult, LocalhostProcessingResult
- pid-tracker.ts: NetTcpEntry
- logs-stats.ts: StatsFormat
- logs-summary.ts: SummaryFormat
- logs-command-helpers.ts: LoggingOptions
- commands/logs.ts: LogsCommandOptions
- logs/log-streamer.ts: StreamOptions
- logs/index.ts: removed StreamOptions re-export
- config-file.ts: AwfFileConfig
- image-tag.ts: ImageDigestKey, ParsedImageTag
- rules.ts: Rule
- docker-manager.ts: SslConfig

Closes #2448, closes #2449, closes #2452, closes #2457, closes #2458,
closes #2459, closes #2460, closes #2461

* revert: restore exported symbols and remove unrelated files

Per review feedback, removing export from types compiled to dist/*.d.ts
(no exports map) is a breaking API change for downstream consumers.
Restore export on all de-exported symbols and remove the unrelated
paper-data JSON and scripts/paper PNG files accidentally included.
