Handle missing player identity safely in asynchronous command rewards - #375
Console rewards can continue after temporary player data has been cleared. Guard missing names across console, player and permission lookups; allow identity-independent console commands and return failures when execution needs unresolved player identity. Preserve saved command expansions and replay checkpoints across asynchronous mixed-command continuation.
Adds an optional failure observer for legacy reward dispatch so callers can record partial or unknown outcomes without changing list dispatch order or retrying completed effects.
Validation: a clean Maven package passed 1,719 unit tests and two packaged-artifact checks. Independent source review returned no findings. The inspected AdvancedCore JAR has SHA-256 ddb42adb6bec6450aed79314b7bf9be36e9f79f0aa38633a36b3ef57418f632e.
The paired VotingPlugin change must embed the updated artifact before using the additive observer API. Hosted CI, Jenkins validation and dependency publication are pending. No merge, release or deployment is included.
Summary by CodeRabbit
Bug Fixes
Console commands no longer proceed when player-dependent placeholders or enabled script placeholders cannot be resolved because player identity is missing.
Blank or missing player names are handled safely during player lookups and permission checks, while permission-provider checks can still proceed.
Saved console commands are replayed correctly after a failed reward attempt.
New Features
Asynchronous reward options can now observe failures without interrupting existing error reporting.
Console command expansion now handles missing player identity and carries replay context through asynchronous execution. Reward options also support an optional async failure observer, which reward failure handling invokes before existing reporting.
Console command expansion now uses a shared helper. Without a player name, the helper rejects player-dependent placeholders and enabled JavaScript segments, and checks applicable PlaceholderAPI placeholders. Player and permission lookup paths guard against null or blank names. Tests cover command expansion, player lookups, permissions, and reward command cases.

Console snapshot checks and async command execution now accept explicit replay state and key. Reward command handling passes this context through execution. Tests cover retry behavior and replay context across asynchronous player availability.

RewardOptions adds an optional async failure observer, and dispatch copies preserve it. Reward failure handling invokes the observer before existing reporting and ignores observer exceptions. Tests cover observer notification, dispatch copies, nested failures, and list fan-out.

Merge Risk: Low · previous review d0fde
Nameless rewards can reject otherwise valid global placeholders, and failure observers installed by reward-event listeners are ignored. These narrow limitations warrant fixes or explicit owner acceptance before merging.

The missing-name guard rejects every recognized PlaceholderAPI token when PlaceholderAPI is enabled, without distinguishing server-wide expansions from player-dependent ones.
A console command that could use server-wide data fails solely because the recipient's name is unavailable.
This can occur when: A nameless user's console command uses an installed global expansion such as %server_online%.

- Around line 1488-1490: Update the async failure handling in giveReward to
resolve the observer from the RewardOptions copy passed through event dispatch
after PlayerRewardEvent fires, rather than capturing it from the caller’s
original options. Ensure an observer set by an event listener on
event.getRewardOptions() is used when dispatch fails.

## Compatibility-first change policy
Compatibility is the default acceptance criterion for every new feature, refactor, fix, storage change, and dependency change. Unless the task explicitly authorizes a breaking change:
- Preserve public and de-facto APIs, constructors, overloads, callback/threading behavior, configuration keys/defaults, serialized forms, database semantics, shaded packages, and reflection-visible names used by downstream plugins.
For the out-of-diff PlaceholderAPI suggestion, unresolved-identity execution remains conservative. The expansion contract does not provide a general guarantee that an arbitrary expansion is independent of its player context. With a valid name, normal expansion behavior is unchanged. Without one, literal or already-expanded commands can execute; identity-dependent expansion returns a meaningful failure rather than silently skipping the reward or guessing a target. Supporting specific global providers would need a separate verified capability contract.
