Add UI components for viewing and managing LLM chat cost analytics.
## Changes
- `UserAnalyticsDialog`: personal cost summary with 30-day date range
- `ChatCostSummaryView`: shared component for cost breakdowns by model
and chat
- `ConfigureAgentsDialog`: admin Usage tab with deployment-wide cost
rollup
- Storybook stories for all new and existing components
- Replace `ModelsSection.test.tsx`, `DashboardLayout.test.tsx`,
`AuditPage.test.tsx` with Storybook stories
- Cost-related API client methods and React Query hooks
- Analytics utilities for formatting microdollar values
Backend: #23036
Add cost tracking for LLM chat interactions with microdollar precision.
## Changes
- Add `chatcost` package for per-message cost calculation using
`shopspring/decimal` for intermediate arithmetic
- **Ceil rounding policy**: fractional micros round UP to next whole
micro (applied once after summing all components)
- Database migration: `total_cost_micros` BIGINT column with historical
backfill and `created_at` index
- API endpoints: per-user cost summary and admin rollup under
`/api/experimental/chats/cost/`
- SDK types: `ChatCostSummary`, `ChatCostModelBreakdown`,
`ChatCostUserRollup`
- Fix `modeloptionsgen` to handle `decimal.Decimal` as opaque numeric
type
- Update frontend pricing test fixtures for string decimal types
## Design decisions
- `NULL` = unpriced (no matching model config), `0` = free
- Reasoning tokens included in output tokens (no double-counting)
- Integer microdollars (BIGINT) for storage and API responses
- Price config uses `decimal.Decimal` for exact parsing; totals use
`int64`
Frontend: #23037
The pre-push hook was removed in #22956. This restores it with a
reduced scope (tests + site build) and an allowlist so it only runs
for developers who opt in.
Two opt-in mechanisms:
- git config coder.pre-push true (local, not committed)
- CODER_WORKSPACE_OWNER_NAME allowlist in the hook script
git config takes priority and also supports explicit opt-out for
allowlisted users (git config coder.pre-push false).

## Summary
- remove the `pre-push` git hook script from the repository
- remove the `make pre-push` target and related Makefile documentation
- update contributor and agent docs so they only describe the remaining
`pre-commit` hook
## Validation
- `make pre-commit`
- `git diff --check`

The `test-postgres` Makefile rule was redundant — CI never used it (it
runs `test-postgres-docker` + `make test` via the `test-go-pg` action),
and `make test` auto-starts a Postgres Docker container when needed via
`dbtestutil`.
- Remove the `test-postgres` rule from Makefile
- Update `pre-push` to run `test-postgres-docker` in the first phase
(alongside gen/fmt) and `make test` in the second phase
- Fix stale comments in CI workflows referencing `make test-postgres`
- Remove redundant "Test Postgres" entries from docs since `make test`
handles Postgres automatically
Agents hit short shell timeouts on `git commit` (~13s) before
`make pre-commit` finishes (~20s warm), then disable hooks via
`git config core.hooksPath /dev/null`. This bypasses all local checks
and, because it writes to shared `.git/config`, silently disables hooks
for every other worktree too.
Add explicit timing guidance to AGENTS.md, and write worktree-scoped
`core.hooksPath` in post-checkout, pre-commit, and pre-push hooks to
make the bypass ineffective.
This change adds git hooks and Makefile targets that mirror CI required
checks locally, catching issues before they reach CI.
This is for use by AI agents (documented in AGENTS.md).
- **pre-commit** (every commit): gen, fmt, lint, typos, slim binary
build. Fast checks without Docker or Playwright.
- **pre-push** (before push): full CI suite including site build, tests,
sqlc-vet, offlinedocs.
To use:
```sh
git config core.hooksPath scripts/githooks
```
Works in worktrees (where `.git` is a file). Bypass with `--no-verify`.
Our `AGENTS.md` previously contained this directive:
> When adding tests for new behavior, add new test cases instead of
modifying existing ones. This preserves coverage for the original
behavior and makes it clear what the new test covers.
This leads to inflated diffs and test explosions. Updating it to bias
more towards updating existing tests where applicable.

When working on PRs, Claude Code was sometimes force pushing to
branches. This adds simple git workflow guidelines that emphasize proper
branch checkout and avoiding force pushes.
## Changes
Added git workflow section to `CLAUDE.md`, `AGENTS.md`, and
`.claude/docs/WORKFLOWS.md` with:
- Instructions to fetch, checkout, and pull before working on PR
branches
- Note to avoid `git push --force` unless explicitly requested
## Examples of force push behavior
Observed in recent PRs:
- PR #21148: 7 commits including merge commit from iterative changes
- PR #21150: 9 commits with multiple documentation iterations
- PR #21182: 4 commits with iterative fixes
- Force update on `feat/add-tasks-template-flag` branch:
`9bf7980b9...f98cf44f7`
The guidelines now make it clear to check out branches properly and push
normally.
