feat(wasteland): configurable upstream — read from mayor/wasteland.json

[pratham-bhatnagar]

Summary

All wasteland read commands (browse, stamps, show, charsheet, scorekeeper) hardcode hop/wl-commons as the upstream database. This makes it impossible to use a private or custom wasteland federation.

This PR reads the upstream configuration from mayor/wasteland.json (already saved by gt wl join) instead of hardcoding, with full backward compatibility.

Changes

Core Infrastructure

internal/wasteland/wasteland.go

• ResolveDBName(townRoot) — derives Dolt database name from config ForkDB field (hyphens → underscores). Falls back to "wl_commons".

internal/doltserver/wl_commons.go

• NewWLCommonsWithDB(townRoot, dbName) — store constructor with custom database name
• DBName() accessor on WLCommons
• Exported QueryCSV() and QueryJSON() for server-side query execution

internal/doltserver/wl_charsheet.go

• Refactored QueryStampsForSubject, QueryBadges, QueryAllSubjects, UpsertLeaderboard into wrapper + DB-parameterized implementations

Command Updates

Command	Change
wl_browse.go	Server fast path when DB registered; config-aware clone fallback
wl_stamps.go	Config local dir check before clone; config-aware upstream
wl_show.go	Server fast path via store; config-aware clone fallback
wl_charsheet.go	ResolveDBName() + NewWLCommonsWithDB()
wl_scorekeeper.go	Same as charsheet
wl_claim.go, wl_stamp.go, wl_done.go	Resolved DB name for existence check

Resolution Order (read commands)

1. Dolt server (if database registered) → query via TCP
2. Config local dir (from mayor/wasteland.json) → dolt sql in directory  
3. Standard location (.wasteland/hop/wl-commons)
4. Common fallback locations
5. Clone-then-discard from config upstream (or hop/wl-commons default)

Backward Compatibility

• No config → falls back to hardcoded hop/wl-commons
• WLCommonsDB constant unchanged
• Package-level functions still use default DB name
• No changes to gt wl join, gt wl post, gt wl sync
• All existing tests pass

Use Case

Anyone running gt wl join <custom-upstream> expects all gt wl commands to work with their configured upstream. Currently only join, post, claim, done, and sync respect the config — read commands ignore it.

Test Plan

• gt wl join <custom/db> saves config correctly
• gt wl browse reads from local fork (no DoltHub clone)
• gt wl show <id> queries through Dolt server when DB registered
• gt wl stamps <handle> works with custom DB name
• gt wl charsheet resolves custom DB from config
• gt wl scorekeeper --json uses resolved database
• All commands fall back to hop/wl-commons with no config
• Builds cleanly from v0.13.0

Notes

Submitted by @pratham-bhatnagar. We run a Gas Town with a private wasteland and discovered these hardcoded paths while setting up federation. Happy to iterate on the implementation.

Updated implementation rebased on latest upstream (9f962c4). All changes on masti-ai/gastown main branch. 12 wl command files patched — browse, show, stamps, charsheet, scorekeeper, claim, done, stamp, post all read from local Dolt server via wasteland.json config. Zero DoltHub cloning. Binary tested and installed.
