Improve vague error messages in channel initialization and tool setup
to include specific config key paths and remediation steps, matching
the quality standard set by proxy validation errors.
Changes:
- telegram.rs: Include [channels.telegram] section path and required
fields (bot_token, allowed_users) in missing-config error; add
onboard hint; specify channels.telegram.allowed_users in pairing
message; improve parse error context
- whatsapp.rs: Specify channels.whatsapp.allowed_numbers key path
in unauthorized-number warning
- linq.rs: Specify channels.linq.allowed_senders key path in
unauthorized-sender warning; add onboard hint
- web_search_tool.rs: Include tools.web_search.provider config path
and valid values in unknown-provider error
Addresses API surface audit §8.2 (config context in error messages).

Add native web search capability that works regardless of LLM tool-calling
support. This is particularly useful for GLM models via Z.AI that don't
reliably support standard tool calling formats.
Features:
- DuckDuckGo provider (free, no API key required)
- Brave Search provider (optional, requires API key)
- Configurable max results and timeout
- Enabled by default
Configuration (config.toml):
[web_search]
enabled = true
provider = "duckduckgo"
max_results = 5
The tool allows agents to search the web for current information without
requiring proper tool calling support from the LLM.
Also includes CI workflow fix for first-interaction action inputs.
