Validate the data on every pull request, and fix everything it found

[je-can-code]

Takes the rmmz-plugins build from je-can-code/rmmz-plugins#121, and gives the data a validator that runs on every pull request.

Validation

• bun run validate checks the seams between the three things that write chef-adventure/data: every data file parses, no backup is committed, js/plugins/j/ is exactly one rmmz-plugins build with nothing stale beside it, every id a notetag or a plugin config names is a real row, and every notetag matches a pattern some plugin declares. What each tag means comes from the manifest.json the build now writes beside the plugins.
• .github/workflows/validate.yml runs it on every pull request and every push to main, after bun run validate:selftest, which plants each kind of bug in memory and fails unless every one is caught.
• package.json is new, as the home of those two scripts, and CLAUDE.md documents both.
• The first run found 63 problems. Everything below fixes them.

Fixes it found

• Deleted four orphaned plugins from js/plugins/j/, a stale source map, and Classes.old.json. .gitignore ignores *.old.json, *.backup* and *.bak*.
• Six enemy combos pointed at skills blanked on Jul 25, and point at live ones again. Ka-peck chains through Ka-peck-peck to Ka-peck-peck-peck.
• Removed the Wolftrap's test passive and the +Shielding extension, from the skill list and from the five enemies that carried it.
• The richpoor quests fetch Wilted Greens and What the Ground Gave, dishes that exist, and name them with \item codes.
• Twelve misspelled tags: hrc to hcr on the Life Cost states, jabsRole to aiRole on the Guardian and Sentinel maps, and dergrees, tpPerc and switchChoiceCondition.
• Renamed juiceRepeatMotion to juiceRepeatCount, animationOnSelf to selfAnimationId, and targeting to targeted.
• Removed <damagePerc:5> from 18 maps. It went with J-CAMods' floor damage, and regions replace it.
• Accelerant speeds up burn ticks with <tickSpeedTypePercent:[burn, 100]>. Untouchable grants 1000% evasion and magic evasion. Smother drains through mpFormula and tpFormula. Careless lowers crit reduction, which the plugins now allow. Skeletor and Kapn Kappa are careful. Equilibrium's growth tag names sar.
• docs/database-decode-cheatsheet.md calls ex-parameter 1 Phys Evade, not Parry Extend.

Growth

• Every natural growth tag is written in status-screen numbers now, and these tags already were, so they behave as authored. Every ex- and sp-parameter class growth is a hundred times what it delivered before, and Trickster's Gambit goes from multiplying drops by level to adding a percent per level.
• Lavos' cdmGrowthPlus reads 1.5, Blind lowers hit with <hitBuffRate:[-10]>, and Deathless Fury's pdr and mdr buffs read -50, all three having been written as fractions.
• Growth accumulated in older saves does not carry over.

Plugins

• J-Base 3.19.0, J-NaturalGrowth 3.0.0, J-CriticalFactors 1.4.0, J-DropsControl 2.6.0, J-ABS-Shield 1.2.0, J-ABS-Speed 1.2.0, J-Aptitude 1.5.0, J-Proficiency 2.5.0, J-Resources 1.2.0, J-Resources-ABS 1.2.0 and J-SDP 4.8.0.

Unrelated, from a sibling thread

• The regen gear (armors 103 to 114) restores a flat amount per tick, from 5 on a band to 250 on a crown, with descriptions to match.
• The armor table ends at 550. The hundred rows removed from its end were blank.
• MapInfos.json and System.json carry editor-save noise.
