chore(license): flip 700 PMPL→AGPL-3.0-or-later SPDX stamps (Phase 1) (#344)

## Summary

First in a per-subdir series for standards PMPL→**AGPL-3.0-or-later**
source-SPDX alignment.

**Note the direction**: standards is category 3 (son-shared per
[[standards-agpl-intentional]]), so source SPDX flips to
`AGPL-3.0-or-later`, **not** MPL-2.0 (which is the sole-owner default
for repos like dev-ecosystem and neurophone).

## Repo state confirmed

- Root LICENSE: AGPL-3.0-or-later ✓
- Source SPDX: 3,553 files carry `PMPL-1.0-or-later` from legacy
carve-out era
- consent-aware-http subdir has its own special hybrid (MPL-2.0 source +
CC-BY-4.0 spec + PMPL-2.0-or-later reference) — EXCLUDED from this PR

## Phase 1 scope (this PR)

**700 files** flipped `PMPL-1.0-or-later` → `AGPL-3.0-or-later`:

| Area | Files |
|---|---|
| Repo root | 28 |
| `docs/` | 319 |
| `.machine_readable/` | 57 |
| ~30 small subdirs with no own LICENSE (meta-a2ml,
session-management-standards, agentic-a2ml, anchor-a2ml,
k9-coordination-protocol, standards-update, scripts, state-a2ml,
ecosystem-a2ml, playbook-a2ml, neurosym-a2ml,
toolchain-readiness-grades, overlay-protocol, a2ml-templates,
.verisimdb, inline-annotations, hooks, launcher, contractiles,
adoption-readiness-grades, panll-panels, hypatia-rules,
foundations-readiness-grades, component-readiness-grades,
publication-pre-flight, ensaid-config, ai-instruction, tasks, standards,
release-pre-flight, tools, testing-and-benchmarking, .meta,
immaculate-guide, .github, accessibility) | ~296 |

## Explicitly EXCLUDED

| Path | Reason | Files |
|---|---|---|
| `a2ml/` | Own PMPL LICENSE — Phase 2 (LICENSE+SPDX to AGPL combined) |
1,171 |
| `k9-svc/` | Own PMPL LICENSE — Phase 2 | 1,160 |
| `rhodium-standard-repositories/` | Own PMPL LICENSE — Phase 2 | 122 |
| `0-ai-gatekeeper-protocol/` | Own PMPL LICENSE — Phase 2 | 107 |
| `lol/` | Own PMPL LICENSE — Phase 2 | 105 |
| `avow-protocol/` | Own PMPL LICENSE + check-in copy of standalone
`hyperpolymath/avow-protocol` — skip (fix in standalone) | 90 |
| `axel-protocol/` | Own PMPL LICENSE — Phase 2 | 49 |
| `consent-aware-http/` | **Special hybrid** licensing (MPL-2.0 src +
CC-BY-4.0 spec + PMPL-2.0-or-later ref) per owner directive 2026-06-02 |
39 |
| `outreach/` | Own LICENSE — Phase 2 review | 10 |

## Pattern this PR follows

- `hyperpolymath/neurophone#102` for SPDX-flip mechanics
- `hyperpolymath/developer-ecosystem#103/#105` for per-subdir scoping
- **First time** the destination is AGPL not MPL — be aware

## Verification

```sh
grep -rl 'SPDX-License-Identifier: PMPL-1.0-or-later' <phase-1-paths>
# returns: 0 files
```

## Why draft

License sweep + first-of-kind AGPL destination; owner sight before
merge.
