[opencode] make bonk fix requests implementation-first

[elithrar]

This updates the Bonk agent prompt so PR fix requests are treated as implementation work instead of suggestion-only review.

The current prompt gives review behavior more specific guidance than implementation behavior, which makes Bonk drift toward comments like the ones on #12970 instead of directly updating the branch.

• make implementation mode the default for fix, address, formatting, and cleanup requests
• add explicit action, PR, and thread-context bias so short review-thread prompts still resolve to direct changes
• add examples for review-only, implementation-first hybrid, and reproduce-then-fix requests

The change is to .opencode/agents/bonk.md only — an internal agent prompt file. This is not a published package, so no changeset is required. The changes restructure the prompt to prioritize implementation mode over review mode when Bonk receives action-oriented requests, which directly addresses the stated problem of Bonk drifting toward suggestion-only comments.

The restructuring is logical:

• XML tags for clear section boundaries
• Explicit mode precedence (implementation > review > triage)
• Concrete trigger examples for each mode
• Positive and negative examples to anchor behavior
• Anti-patterns updated to include the bad behavior being fixed

No logic bugs, security issues, backward compatibility concerns, or incorrect API behavior. The file is an internal prompt with no runtime impact on any published package.

LGTM

Clean restructuring that directly addresses the problem described in #12970. The XML-tagged sections, explicit mode precedence, and positive/negative examples should all help anchor behavior toward implementation when action is requested.

Two minor observations (non-blocking):

1. The <non_negotiable_rules> section packs a lot of behavioral guidance (action bias, PR bias, thread-context bias) alongside scope constraints. If Bonk still drifts, splitting the biases into their own section could make them harder to skip over during prompt processing — but worth seeing how this version performs first.

2. The implementation workflow step 4 is doing double duty: on issues it searches for overlaps, on PRs it establishes the current PR as the target. These are quite different actions. If step 4 grows more complex later, splitting it would improve clarity.

Neither of these is worth changing now — the restructure is a clear improvement over the previous version. LGTM.

[ask-bonk]

Approved PR #12993. The restructuring is solid — the XML-tagged sections, explicit mode precedence (implementation > review > triage), and concrete positive/negative examples should effectively anchor Bonk toward direct implementation when action verbs are used, which addresses the drift toward suggestion-only comments seen in #12970. Left two minor non-blocking observations about potential future refinements.
