Website: guides and glossary catch up with spec 0.4 (audit, #257, #262) - #266

Fixes the website audit (docs-audit/website.md, 43 findings) against current main, and covers what #257 and #262 mean for app developers. Website only, so no changeset.

Per file

• guides/other-characters.md
  • Auras: the sample now uses 5E's Aura of Protection on an ally statted with the same pack (the old one put a Draw Steel aura on a 5E goblin). Shows the real entry (the copy that holds it, paladin), gives each placed entry an ID and shows its removal, and names the aura's text key.
  • appliers on all five calls, with applyChanges' positional order (7th, after strict, links, dice).
  • Event samples keep the observer's and the talent's returned files; a bullet says why (offers live in the file).
  • Handoffs: an action effect without as runs on the actor, pausing at its path.
  • Turns: pass links and appliers. Cast auras: "orc-2e's bless or 5E's Spirit Guardians".
  • Both samples were run against the current engine (scratch scripts, not in the repo): the aura entry, the save going from 2 to 4 with the view, removeEffect, and the tactician's mark-damaged-1 stored in its file.
• guides/showing-text.md: addedParam/addedParamValue/addedParamDescription in the Forms sample, templateFieldDescription, a "Situational choices" section (situational, situationalValue), an "Effects and auras" section saying plainly there is no aura helper (look up <source>.auras.<aura>.name with text.message, fall back to the source's name), stepPrompt/stepName, and invalid-param/boundBy text. Outputs checked with the text package.
• guides/changing-characters.md: the five missing change types (finishCreation, offerFollowUp, clearFollowUp, dismissFollowUp, observe) with links; applyEffect names appliedBy and aura; naming offered reactions; a held copy's state from a choice's cost doesn't clamp (Spec: a situational choice's changes reach held copies' state (#244) #257).
• guides/storing-characters.md: appliedBy, aura, state on applied entries and entry on addAs: copy picks; caches depend on links and appliers.
• guides/showing-a-sheet.md: auras and observes rows; effectsWhen; aura immunity issue IDs; re-key competing picks saved under rules/… (Spec: rules choice issue IDs name their pack, unchoose by owner, list of integer #240).
• guides/text-and-translation.md: key rows for added parameters, content computed values, auras, inline option descriptions, and a rules-level choice's issue (<pack>:rules/<choice>); {self_<key>} covers computed values; invalid-param and boundBy in errors.
• guides/upgrading-characters.md: changeContentType and grantsToCopies, grant-not-copied, and a "What your app passes in" section (removed or narrowed parameters and situational choices, parameters made derived; a removed parameter's value is ignored, checked against the engine).
• guides/rolling-dice.md: "PF2e's Hero Points" becomes "orc-2e's Hero Points"; bounds that read params aren't listed; derived parameters are never passed and participant errors come first (Spec: derived parameters, computed values in action-time effects, bounds on an action's own parameter (#251, #252) #262); continue a paused action with the ruleset it started with; roll items' tags.
• guides/building-characters.md: picked-copy-invalid; rules-level choice issue IDs.
• guides/implementing.md, quick-start.md, README.md: level 6 covers shared sheets, auras, turns and events; level 5 lists describeAction; "no runtime dependencies" becomes "doesn't depend on Node" (the engine depends on @opencharacter/spec and semver).
• guides/packs-and-rulesets.md: LicenseRef- packs (Draw Steel, the Sine Nomine games) carry a credit and a permission notice.
• glossary.md: new Activation, Added parameter (with addedBounds/boundBy), Shared action; updated Effect operation (action), Handoff, Interface change, Shape change, Proposed change, Situational choice (held copy costs).
• scripts/sync-docs.ts (separate commit): the home packs table names LicenseRef-draw-steel-creator-license and LicenseRef-sine-nomine-free-edition, drops the unused OGL-1.0a, and adds a footnote.

Skipped

• Finding 12 (pending Effects can't read computed values, and nothing derives a value from an action's parameters #251/A params effect can't bound a parameter the action already declares #252): merged in Spec: derived parameters, computed values in action-time effects, bounds on an action's own parameter (#251, #252) #262, which already updated rolling-dice and the glossary; the remaining checks are done above.
• Finding 19 (Spec: a situational choice's changes reach held copies' state (#244) #257 changing-characters bullet): Spec: a situational choice's changes reach held copies' state (#244) #257 already updated it; only the no-clamp note was added.
• Finding 43: no change needed (generated table, version pins rewritten by pnpm version-packages).
• Finding 41's "Shared action": defined as the spec does (a rules action items use), not as the audit's wording.
