feat(Core/Playerbots): Initialize bot professions and specializations (#2287)
## Pull Request Description

Initialize random bot professions from the factory using class-matching
or weighted-random profession pairs, respect the active primary
profession cap, and restore required profession tools during bot
init/refresh.

This PR also initializes profession specializations for eligible bots so
crafted professions are not left in an unspecialized state after
profession assignment. Supported specialization families include:

- Alchemy: Transmute / Elixir / Potion
- Engineering: Goblin / Gnomish
- Leatherworking: Dragonscale / Elemental / Tribal
- Tailoring: Spellfire / Mooncloth / Shadoweave
- Blacksmithing: Armorsmith / Weaponsmith, plus Hammersmith / Axesmith /
Swordsmith for eligible Weaponsmith bots

Specialization choices are stored in bot values so they remain stable
across later refreshes. Required tool items are also restored for
relevant professions during maintenance.

## Feature Evaluation

- Describe the **minimum logic** required to achieve the intended
behavior.
- Select one or two professions during factory initialization from a
small weighted list.
- Clamp the assigned professions to the configured primary profession
limit.
- Learn the profession starter spell and set skill to the bot’s
profession cap.
- For professions with supported specialization branches, assign exactly
one valid specialization when the bot meets the same level/skill gates
used by AzerothCore profession scripts.
- Persist the specialization selection in stored bot values so the
choice is stable and does not need to be recalculated repeatedly.
- Restore missing profession tools only when the bot has the related
profession and the tool is absent.

- Describe the **processing cost** when this logic executes across many
bots.
- The added logic executes only during bot init/refresh, not as part of
per-tick combat or trigger evaluation.
- Runtime cost is limited to a few small switch statements, stored value
lookups, spell checks, and item presence checks.
- No expensive repeated searches, map scans, or per-trigger decision
trees were added.
- The design keeps specialization selection deterministic after first
assignment by storing the result, avoiding repeated random branching
later.

## How to Test the Changes

1. Build and restart the server with this branch.
2. Trigger random bot creation, refresh, or level-based reroll for
multiple bots.
3. Verify in `Playerbots.log` that bots receive profession pairs and,
when eligible, profession specializations.
4. Check that low-level bots do not receive specializations before the
required thresholds.
5. Check that eligible bots do receive one specialization for supported
profession families.
6. Verify that specialization choices remain stable across subsequent
refreshes.
7. Verify that profession tools are restored when missing:
   - Mining Pick
   - Blacksmith Hammer
   - Arclight Spanner
   - Runed Arcanite Rod
   - Skinning Knife
8. For a few bots, inspect in game or via debug tooling that profession
spells/specialization spells are present as expected.

Expected behavior:
- Bots receive professions that respect the configured primary
profession limit.
- Profession skill values are initialized to the level-based cap.
- Eligible bots receive exactly one valid specialization for supported
profession families.
- Specialization assignments are logged and persist across refreshes.
- Profession tools are restored only when required.

## Impact Assessment

- Does this change increase per-bot/per-tick processing or risk scaling
poorly with thousands of bots?
    - - [ ] No, not at all
    - - [x] Minimal impact (**explain below**)
    - - [ ] Moderate impact (**explain below**)

  Explanation:
- The added work runs during initialization/refresh rather than normal
per-tick behavior.
- Logic is bounded, data-local, and based on direct skill/spell/value
checks.

- Does this change modify default bot behavior?
    - - [ ] No
    - - [x] Yes (**explain why**)

  Explanation:
- Bots can now start with initialized professions, required tools, and
eligible profession specializations instead of remaining partially
configured or unspecialized.

- Does this change add new decision branches or increase maintenance
complexity?
    - - [ ] No
    - - [x] Yes (**explain below**)

  Explanation:
- The factory now contains specialization assignment branches for
supported profession families.
- Complexity is intentionally limited to init-time switch-based logic
with stored specialization values to preserve predictability.

## AI Assistance

Was AI assistance used while working on this change?
- - [ ] No
- - [x] Yes (**explain below**)

AI assistance was used for:
- code generation and refactoring in `PlayerbotFactory`
- drafting and refining profession/specialization initialization logic
- PR description preparation

All generated and suggested code was reviewed, adjusted, built locally,
and validated before submission.

## Final Checklist

- - [x] Stability is not compromised.
- - [x] Performance impact is understood, tested, and acceptable.
- - [x] Added logic complexity is justified and explained.
- - [x] Any new bot dialogue lines are translated.
- - [x] Documentation updated if needed (Conf comments, WiKi commands).

## Notes for Reviewers

- Target branch is `test-staging`.
- Profession/specialization logic is intentionally limited to
init/refresh paths to avoid per-tick cost.
- Specialization selections are stored to keep bot behavior stable
across later refreshes.
- Recent changes also add debug logging for assigned specializations and
save the bot after specialization learning so assignments are visible
and persisted.

Playerbots Module

mod-playerbots is an AzerothCore module that adds player-like bots to a server. The project is based off IKE3's Playerbots.

Features include:

  • The ability to log in alt characters as bots, allowing players to interact with their other characters, form parties, level up, and more
  • Random bots that wander through the world, complete quests, and otherwise behave like players, simulating the MMO experience
  • Bots capable of running most raids and battlegrounds
  • Highly configurable settings to define how bots behave
  • Excellent performance, even when running thousands of bots

We also have a Discord server where you can discuss the project, ask questions, and get involved in the community!

Installation

Supported platforms are Ubuntu, Windows, and macOS. Other Linux distributions may work, but may not receive support.

Important: All mod-playerbots installations require a custom fork of AzerothCore: mod-playerbots/azerothcore-wotlk (Playerbot branch). The standard AzerothCore repository will not work.

Quick Start

git clone https://github.com/mod-playerbots/azerothcore-wotlk.git --branch=Playerbot
cd azerothcore-wotlk/modules
git clone https://github.com/mod-playerbots/mod-playerbots.git --branch=master

Then build the server following the platform-specific instructions in our Installation Guide.

Testing branch: A test-staging branch is available with the latest features and fixes before they are merged into master. To use it, clone with --branch=test-staging instead. Note that this branch may contain unstable or breaking changes — use it at your own risk and only if you are comfortable troubleshooting issues.

Detailed Guides

Documentation

The Playerbots Wiki contains an extensive overview of AddOns, commands, raids with programmed bot strategies, and recommended performance configurations. Please note that documentation may be incomplete or out-of-date in some sections, and contributions are welcome.

Bots are controlled via chat commands. For larger bot groups, this can be cumbersome. Because of this, community members have developed client AddOns to allow controlling bots through the in-game UI. We recommend you check out their projects listed in the AddOns and Submodules page.

Contributing

This project is still under development. We encourage anyone to make contributions, anything from pull requests to reporting issues. If you encounter any errors or experience crashes, we encourage you report them as GitHub issues. Your valuable feedback will help us improve this project collaboratively.

If you make coding contributions, mod-playerbots complies with the C++ Code Standards established by AzerothCore. Each Pull Request must include all test scenarios the author performed, along with their results, to demonstrate that the changes were properly verified.

We recommend joining the Discord server to make your contributions to the project easier, as a lot of active support is carried out through this server.
