Fix CS8618 warnings by adding null-forgiving operator (!) or default values to non-nullable properties in DTO/model classes. Files changed: - Env.cs (static fields + Config class) - LlmContinuationSnapshot.cs - LlmExecutionContext.cs - ModelWithCapabilities.cs - PaddleOCRPost.cs - PaddleOCRResult.cs - OCRTaskPost.cs - OCRTaskResult.cs - ShortUrlMappingResult.cs - BuiltInToolAttributes.cs - McpAttributes.cs Note: Remaining warnings (CS0612/CS0618/CS8424/CS8602) are from: - Obsolete attribute usage (cannot fix without design change) - Third-party packages (NU1901/NU1701/SourceLink)

In `@TelegramSearchBot.Common/Env.cs`:
- Around line 79-103: Add a new docs page under Docs/ that documents the
persistent Config.json used by Env.cs (the Config class), including where to
place the file (%LOCALAPPDATA%/TelegramSearchBot/Config.json), the JSON
format/schema, and a short description, type and default value for each property
found on the Config class (e.g., BaseUrl, BotToken, AdminId, EnableAutoOCR,
EnableAutoASR, IsLocalAPI, EnableLocalBotAPI, TelegramBotApiId,
TelegramBotApiHash, LocalBotApiPort, SameServer, TaskDelayTimeout,
OllamaModelName, EnableVideoASR, EnableOpenAI, OpenAIModelName, OLTPAuth,
OLTPAuthUrl, OLTPName, BraveApiKey, EnableAccounting, MaxToolCycles); include a
minimal example JSON template and instructions for secure storage of secrets
(BotToken, API keys) and how to restart the app after editing Config.json.
In `@TelegramSearchBot.Common/Model/AI/LlmExecutionContext.cs`:
- Line 21: Change the SnapshotData property on LlmExecutionContext to be
nullable instead of using the null-forgiving initializer: replace "public
LlmContinuationSnapshot SnapshotData { get; set; } = null!;" with a nullable
declaration like "public LlmContinuationSnapshot? SnapshotData { get; set; }"
(remove the "= null!" initializer); this aligns the type with conditional
initialization and existing null-checks (e.g., checks against
executionContext.SnapshotData) and improves type safety—update any XML comments
on the SnapshotData property if present.
In `@TelegramSearchBot.Common/Model/AI/ModelWithCapabilities.cs`:
- Around line 60-62: The change alters ModelWithCapabilities.GetCapability to
return string.Empty for missing keys which breaks callers/tests expecting null;
revert to the previous contract by making the method return a nullable reference
(change signature to public string? GetCapability(string capabilityName)) and
return null when Capabilities.TryGetValue(...) is false (i.e., replace
string.Empty with null), keeping the lookup via Capabilities.TryGetValue intact
so callers/tests that expect null continue to pass.
In `@TelegramSearchBot.Common/Model/Tools/BraveSearchResult.cs`:
- Around line 5-7: The DTOs currently assert non-null with null! but the
external Brave API often omits fields; update all properties in
BraveSearchResult, BraveWebResults, BraveResultItem, and BraveProfile to
nullable types (e.g., string? and BraveProfile?), remove null! initializers, and
ensure any collections or nested DTO references are also nullable so
deserialization can produce true nulls without violating the type system; adjust
any callers that assume non-null or add null checks where necessary.
In `@TelegramSearchBot.Common/Model/Tools/SearchToolModels.cs`:
- Line 16: The properties ContentPreview and Content are declared as non-null
with = null! but callers assign potentially-null values; change their types from
string to nullable string (string?) on the SearchToolModels class so the
nullable contract matches assignments (update the ContentPreview and Content
property declarations to use string? and adjust any related consumers or
mappings if needed).

This PR introduces a new persistent configuration system (Env.cs loading from %LOCALAPPDATA%/TelegramSearchBot/Config.json), which requires documentation updates per coding guidelines.

- How to create and populate
Config.json - All 23 configuration properties and their purposes

Make SnapshotData nullable to match conditional initialization.
The property is initialized with null! and documented as present only when iteration limit is reached. All call sites already null-check before dereference (e.g., if (executionContext.IterationLimitReached && executionContext.SnapshotData != null)). Making it explicitly nullable removes the null-forgiving operator and improves type safety.

Make all BraveSearchResult DTO properties nullable to reflect actual deserialization behavior.
External API responses are incomplete by design, and JsonConvert.DeserializeObject produces null values for missing fields. The null! declarations create a false safety contract that masks these runtime nulls and can hide bugs during development. Change all string and object properties in BraveSearchResult, BraveWebResults, BraveResultItem, and BraveProfile to nullable (e.g., string?, BraveProfile?) to accurately represent what the deserializer produces.

In `@TelegramSearchBot.Common/Model/Tools/SearchToolModels.cs` at line 16, The
properties ContentPreview and Content are declared as non-null with = null! but
callers assign potentially-null values; change their types from string to
nullable string (string?) on the SearchToolModels class so the nullable contract
matches assignments (update the ContentPreview and Content property declarations
to use string? and adjust any related consumers or mappings if needed).
