## Description

Adds workflow-level concurrency controls to all three orchestrator
workflows. This prevents unnecessary parallel runs when multiple commits
are pushed in quick succession and reduces GitHub Actions resource
consumption.

**Changes:**

- Added `concurrency` block to `pr-validation.yml` with
`cancel-in-progress: true` to cancel stale PR validation runs when new
commits arrive
- Added `concurrency` block to `main.yml` with `cancel-in-progress:
false` to prevent cancellation of main branch builds
- Added `concurrency` block to `weekly-security-maintenance.yml` with
`cancel-in-progress: false` for scheduled job protection
- Updated `.cspell/general-technical.txt` with missing dictionary terms
(`carryforward`, `SCHED`, `SECCHECK`) that were causing pre-existing
spell-check failures

## Additional Notes

### Concurrency Configuration Patterns

| Workflow | Group Key | Cancel In-Progress | Rationale |
|----------|-----------|-------------------|-----------|
| `pr-validation.yml` | `workflow-head_ref` | `true` | Cancel stale PR
runs when new commits arrive |
| `main.yml` | `workflow-ref` | `false` | Protect main branch builds
from cancellation |
| `weekly-security-maintenance.yml` | `workflow` | `false` | Single
weekly job, no ref variation needed |

### Dictionary Updates

Fixed pre-existing spell-check gaps that passed CI due to timing:

- `carryforward` - Codecov configuration term (PR #250)
- `SCHED`, `SECCHECK` - Mermaid diagram labels (PR #252)
