[Ready for Review] Overall Docs update

[ankitzm]

What changed

• Added docs/getting-started.md — first-run setup walkthrough (replaces the old SETUP.md)
• Added docs/configuration.md — config keys reference and how to set them
• Added docs/arch.md — architecture overview
• Moved commands.md → docs/commands.md (consolidated under docs/)
• Renamed contributing.md → CONTRIBUTING.md (standard casing GitHub recognizes)
• Removed SETUP.md — folded into docs/getting-started.md
• Trimmed README.md (~140 lines removed) and re-pointed all links at the new docs/ tree
• Updated cross-links in CHANGELOG.md, .github/ISSUE_TEMPLATE/config.yml, install.sh, and CLAUDE.md to the new doc paths
• Minor .gitignore cleanup

Why

Documentation was scattered across the repo root (SETUP.md, commands.md, contributing.md) with overlapping content and stale links. This consolidates everything under a single docs/ tree with a clear entry point (getting-started.md), giving new users one obvious path in and keeping the README short. The code behind this (embedded/no-Docker default) is already merged into the target — this PR is the documentation catch-up.

How to test

1. Open README.md — every doc link should resolve to a file under docs/ (or CONTRIBUTING.md); no dead links to the removed SETUP.md or root-level commands.md.
2. Open docs/getting-started.md and follow it end-to-end — commands and references should match current CLI behavior.
3. Spot-check docs/configuration.md against actual config keys (bytebell set …) — keys and defaults should line up.
4. Confirm CONTRIBUTING.md renders and is linked from the README / issue templates.
5. Check install.sh and the issue-template config.yml links point at the new docs/ paths.

Checklist before [DONE]

• Branch name follows the rules (docs/overall)
• Title starts with a status tag
• What / Why / How to test sections present
• N/A — docs only, no UI/frontend changes (no screenshots)
• CI passes
• Self-reviewed the diff — no broken links left behind
• Rebased on merge/embedded_prerelease so the diff is clean

[Dead-Bytes]

needs to updated with open-ir as reference instead of bytebell pubic

[ankitzm]

[Dead-Bytes]

add a video while filling the setup form that would be great in readme @ankitzm

[bharatsachya]

please add logo here and also remove run it in 5 minutes, also a description like immediate representation of your codebase sounds more intresting
