Explain agent history recovery and multilingual onboarding

[yeelam-gordon]

Developer benefit

Help developers find and resume existing coding-agent conversations without confusing the tool with a generic terminal multiplexer or complete agent orchestrator.

Changes

• Lead with retained-history search/resume and qualified Windows Terminal tab focus.
• Provide complete release-package and source-config first-use routes.
• Move remote-grouping privacy guidance before launch and document the wordmatch choice.
• Add six localized quick starts, troubleshooting and safe update/removal guidance.
• Bound provider/competitor/search claims and attribute historical private-corpus measurements.

Documentation only: no Rust code, provider definitions, grouping defaults, dependencies or histories change.

Validation

Updated stable compiler: both mandatory release clippy gates pass; cargo test --lib passes (227 passed, one ignored). Local links/fragments, TOML examples and config-generator targets were checked. No live provider authentication/session exercise is claimed.
