v2.1.1

Added

• A documentation site (mdBook, with search) at kabirnarang39.github.io/pando/docs:
  getting started, coming from git, deploying, and AI agents and SDKs, alongside the
  architecture, design decisions and benchmarks.
• New logo, README, landing page and social preview. Charts and diagrams are generated
  as light and dark SVGs by scripts/charts.py.
• bench/ci_checkout_load.py: concurrent CI checkouts on one machine, for git and Pando.

Fixed

• Checkouts that write many files in parallel could fail with File exists (os error 17)
  when two writers created the same new directory at once (seen in about 3% of concurrent
  CI checkouts of git/git's t/).
• The MCP tools still used the pre-rename prefix: sap_cat, sap_land and the others are
  now pando_cat, pando_land and so on. MCP clients discover tool names, so agents pick
  up the new names on restart.
• Commands that work without a workspace (cat, ls, log, ...) suggested a --server
  flag they do not have; the error now points to PANDO_SERVER.

Security

• Release archives get signed SLSA build provenance and an SPDX SBOM through GitHub
  artifact attestations (verify with gh attestation verify); container images carry
  provenance and SBOM attestations. See SECURITY.md.
• OpenSSF Scorecard runs weekly and on every push to main.
