Replaces today's `keyLimitUsd = min(walletBalance, $25)` with population-aware
buffers so users can use 100% of their credits before being paywalled, and
opaque mid-run "more credits" failures (e.g. https://github.com/pullfrog/app/actions/runs/25531633203)
get a clear PR comment instead of a generic stack-trace dump.
Policy matrix:
- Auto-reload accounts: `wallet + autoReloadAmountCents` (default $50, no cap)
- Card + no-autoreload: `wallet + $5` overdraft buffer
- No card: `wallet` (no buffer; existing zero-balance 402 stays)
- OSS: `$10` (unchanged)
Removes the $25 per-run cap entirely. Long Build runs at high-balance
accounts no longer silently cap at $25.
Other changes:
- Classify mid-run OpenRouter "requires more credits, or fewer max_tokens"
errors as `router_keylimit_exhausted` BillingError so users get an
actionable PR comment.
- Override OpenCode `max_tokens: 32000` default to `5000` via
OpenCodeConfig.limit.output. Drops Opus per-call upfront budget reservation
from ~$2.40 to ~$0.38 — what makes low-wallet runs viable at all.
- Switch `findInitialComment` and `findExistingPaywallComment` to GraphQL
`issueOrPullRequest(number:) { comments(last: 100) }` (single round trip,
actually returns newest-100; REST listComments doesn't support sort/direction).
Also fixes a latent `comments.find()` returning the OLDEST match instead
of the most recent — now selects max(databaseId).
- Wrap `syncAccountUsage` in `prisma.$transaction` with `SELECT ... FOR UPDATE`
on the account row. Pre/post-balance reads inside the transaction enable
deterministic low-balance edge detection (currently logs; will push the
outreach.low_balance task once #592 lands).

* fix(action): tighten provider error detection and propagate agent error events
Both bugs from #562:
1. detectProviderError used substring matches against "429", "rate limit",
etc. — false-positives on commit SHAs containing 429 and on x-ratelimit-*
response headers in dumped 401 error JSON. rewrote with anchored regexes:
numeric status codes only match adjacent to a recognised status key, and
`\brate[_ ]limit(?=[_ ]|\b)` rejects ratelimit-* headers (no separator).
word-boundary anchors on INTERNAL / UNAVAILABLE / quota / limit:0 reject
INTERNAL_SERVER_ERROR / time_limit:0 substrings. added 11-case regression
test.
2. opencode 401s slipped through `eventCount === 0 && lastProviderError`
because opencode's own type=error event increments eventCount before
the guard runs. added an explicit `error:` handler that captures the
event and propagates it to a non-success AgentResult. opencode emits
the message under `error.data.message`, not the top level. mirror fix
in claude.ts: error_max_turns / error_during_execution / any error*
subtype on the result event now flips success: false.
* fix(action): match quota inside identifiers like insufficient_quota
\bquota\b missed insufficient_quota / quota_exceeded / quotaExceeded
because _ is a word character and camelCase has no boundary. quota is
specific enough to be matched as a plain substring.
* fix(action): match `rate limited` and `rate limits exceeded`
Drop the trailing `(?=[_ ]|\b)` lookahead from the rate-limit regex. The
lookahead failed when `limit` was followed by another word character
(`limited`, `limits`), so `rate limited` and `rate limits exceeded` were
slipping past detection. The leading `\b` plus `[_ ]` separator already
rejects `x-ratelimit-*` / `anthropic-ratelimit-*` headers without it.
