docs: add privacy-first AI agent workflows

[TimeToBuildBob]

Summary

• add an ActivityWatch with agents and AI guide near the data/query examples
• document canonical-events-first workflows, local aggregation, review-before-send, and sensitive-field defaults
• cross-link the guide from querying data, exporting data, categorization, REST API, and the examples index

Addresses ActivityWatch/activitywatch#1388.

Verification

• make html passes locally after poetry install
• Build still emits existing repo warnings for changelog labels, missing media files, missing aw_qt, unknown :docs: roles, and Graphviz availability; no new warning points at src/examples/agents-and-ai.rst or the changed cross-link pages.

Greptile Summary

The PR adds a privacy-first guide for using ActivityWatch data with AI assistants and agents.

• Demonstrates bounded canonical-event queries and local aggregation.
• Recommends redaction, payload review, and local-first processing.
• Cross-links the guide from related API, export, categorization, and data-query documentation.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains; the revised canonical-events example constructs the query with the current client API, executes it for the bounded time range, and processes the returned event dictionaries correctly.

Important Files Changed

Filename	Overview
src/examples/agents-and-ai.rst	Adds the central AI-agent workflow guide; the corrected canonical-query example now follows the current client API and handles its JSON result shape.
src/examples.rst	Adds the new guide to the examples index and describes its purpose.
src/examples/working-with-data.rst	Links readers handling canonical ActivityWatch data to the privacy-first AI workflow.
src/api/rest.rst	Directs agent integrations toward bounded and aggregated access rather than raw events.
src/features/categorization.rst	Recommends categorized summaries as the default input for AI-assisted analysis.
src/features/exporting-data.rst	Warns readers to aggregate and redact exported data before model upload.
