docs: restructure public docs

[altaywtf]

Summary

• Restructure the README around install, quick start, snapshots, commands, and docs navigation
• Move contributor and release mechanics into Contributing and Distribution
• Clarify Fin wording as Intercom-exposed conversation metadata instead of a separate provider
• Add a compact pull request template for verification and tenant-data boundary checks

Verification

• ./scripts/verify
• ./scripts/release-check
• go run ./cmd/fincrawl guard --json
• Markdown local link check
• stale wording/residue scan

Data Boundary

• No tenant credentials, identifiers, real transcript data, generated snapshots, logs, reports, screenshots, or transcript-derived examples added.

Complexity

• Reduced: top-level README is shorter and release/contributor detail has a clearer home.
