chore(calm-suite): A3 — git mv calm-suite/* to repo root

Promotes the two calm-suite sub-projects to top-level workspaces:
- calm-suite/calm-studio/ → calm-studio/
- calm-suite/calm-guard/  → calm-guard/
- calm-suite/DEPLOYMENT-RECONCILIATION.md → DEPLOYMENT-RECONCILIATION.md

Removes the now-empty calm-suite/ directory.

This is a PURE-RENAME commit — zero file content changes — so git's
rename detection preserves the full `git log --follow` chain on every
moved file. CI workflow paths, root workspaces glob, CODEOWNERS,
README, lockfile, and other path-bearing config land in the next
commit.

Refs finos#2649 (Track A), finos#2600 (parent epic). PR finos#3 of the 5-PR Phase 1
sequence; A1 (finos#2661) + A2 (finos#2664) merged.
