Why

Recall shipped in 0.161.0 and 0.162.0, but the homepage, README and docs home did not mention it, the docs never showed it answering a question, and nothing said when to use Recall rather than sinks or the execution history API. The roadmap and feature comparison still listed ClickHouse as a future adapter.

Changes

• Homepage step 09 "Investigate": an audit starts warning, sqb recall output shows what the build printed, and --backend warehouse finds the bad row and its cause. Real output from the example project, run on 0.162.0.
• Recall page: the same investigation, start to finish, with full output.
• Observability overview: a "Which to use" table (Recall, sinks, execution history, final JSON); compute log files described as also stored by Recall.
• Execution history: points readers investigating past runs to Recall.
• ClickHouse and SQLite adapter pages: a short Recall store section.
• README and docs home: Recall section, sqb recall in the command table, ClickHouse and SQLite in the adapter list.
• Roadmap and feature comparison: ClickHouse and SQLite are shipped (beta); Recall in the observability row.
• Regenerated skill reference pages.

Verification

• Website build (114 pages) and scripts/check_links.py: 0 broken links.
• Every output block captured from real runs of the waffle shop example with sqlbuild 0.162.0.
