docs(plugins): drop unreachable repo-root LICENSE pointer from 13 READMEs (wave 2)

[kyle-sexton]

No linked issue — wave 2 of 3; #537 stays open until all 39 plugins are done.

Same recipe as wave-1 PR #755 for the next 13 plugins alphabetically; guardrails is deferred to wave 3 because two in-flight guardrails version bumps (#757 lane) serialize ahead of it. Per-plugin patch bump + CHANGELOG entry; discovery and docs-hygiene entries carry dates per those plugins' own changelog convention.

Verification: repro grep returns 0 hits over the 13 wave-2 READMEs; all 13 manifest versions match their CHANGELOG top entry; base predates #755 so wave-1 plugins intentionally still carry the pointer here (no file overlap between waves).

Findings

No security issues found.

This PR makes three mechanical changes to 13 plugins, all documentation/metadata only:

File type	Change
README.md (×13)	Removes a dead link to an unreachable LICENSE file; leaves the SPDX identifier in place
CHANGELOG.md (×13)	Appends a changelog entry for the doc-only change
plugin.json (×13)	Patch version bump (e.g. 0.8.0 → 0.8.1)

None of the changed files introduce executable code, modify GitHub Actions workflows, alter dependency pins, add external URLs, touch credential or secret handling, or change any permission surface. The $schema references in plugin.json (pointing to https://json.schemastore.org/claude-code-plugin-manifest.json) are unchanged from their pre-existing values. The removal of the broken repo-root LICENSE pointer is a minor correctness improvement with no security consequence.

PR Review — Wave 2 LICENSE pointer cleanup

• Gather context and diff
• Verify version bumps match CHANGELOG top entries
• Verify CHANGELOG date convention per plugin
• Verify README changes are consistent across all 13 plugins
• Confirm guardrails is correctly excluded

Summary

Clean, mechanical PR. All 13 plugins are consistently handled. No issues found.

Version bumps — every plugin.json is a correct +0.0.1 patch increment; each new version matches the top CHANGELOG entry:

Plugin	Old	New
discovery	0.8.0	0.8.1
docs-hygiene	0.7.0	0.7.1
domain-driven-design	0.2.0	0.2.1
education	0.3.1	0.3.2
eol-normalizer	0.4.1	0.4.2
event-storming	0.5.4	0.5.5
firecrawl	0.3.0	0.3.1
implementation	0.7.4	0.7.5
kindle-dedrm	0.6.1	0.6.2
knowledge	0.8.1	0.8.2
machine-health	0.6.0	0.6.1
mcp-tools	0.2.1	0.2.2
planning	0.22.2	0.22.3

CHANGELOG date convention — discovery and docs-hygiene carry — 2026-07-20 in the new entry header; the other 11 omit dates. Both are correct: each plugin's new entry format matches its own prior-entry convention, consistent with the PR description's explicit callout.

CHANGELOG wording — identical across all 13 plugins; no drift.

README changes — all 13 reduce the License section from a two-line pointer (See the LICENSE file at the root of the melodic-software/claude-code-plugins repository.) to a single line (MIT (SPDX-License-Identifier: MIT).). Correct fix: the repo-root LICENSE is unreachable from an installed plugin cache.

Scope — exactly 39 files changed (13 × 3). guardrails is correctly absent (deferred to wave 3). No wave-1 plugin files touched (confirmed by the diff). No extraneous changes.

LGTM — ready to merge.
