Adds the canonical .golangci.yml (v2 layout, default: all with the standard disable list) and pins golangci-lint v2.12.2 everywhere it is referenced.

Version pins

Makefile deps target: go install now uses github.com/golangci/golangci-lint/v2/cmd/golangci-lint@v2.12.2, replacing @latest on the old v1 module path.
Dockerfile lint stage already pinned golangci/golangci-lint:v2.12.2-alpine by digest; unchanged.
script/bootstrap installs golangci-lint via the system package manager (nix/brew/apk) and carries no version pin; unchanged.

Lint fixes

The repo previously had no .golangci.yml, so the strict config surfaced 174 issues, all fixed with no behavior changes:

err113 (12): wrapped static sentinel errors instead of dynamic fmt.Errorf
gocognit/funlen/nestif: split ExtractDay, Run, DumpAndCompress, VerifyOutput, and CLI date parsing into smaller helpers
noctx (10): ExecContext/QueryContext/QueryRowContext/BeginTx and exec.CommandContext
noinlineerr (42) and wsl_v5 (46)/nlreturn (16): statement layout fixes
lll (24): wrapped long lines and SQL strings
gosec (11): filepath.Clean on opens/creates, bounded uint64 conversion in CheckFreeSpace, named output-dir permission constant
mnd (4): unix.FADV_SEQUENTIAL/unix.FADV_WILLNEED and named constants
revive (11): package and exported symbol comments
testpackage/paralleltest: smoke test moved to bsdaily_test with t.Parallel()
nonamedreturns (2), unqueryvet (7), gochecknoglobals (1)

Remaining //nolint directives, each justified inline: gosec G204 for the sqlite3/zstdmt/zstdcat/head subprocesses (internally constructed paths and fixed arguments), and unqueryvet for the intentional full-row SELECT * copies whose schema is defined by the source database.

TODO.md Completed Steps updated. make check is green.

Add the canonical .golangci.yml (v2 layout, default: all with the
standard disable list) and pin golangci-lint v2.12.2 in the Makefile
deps target using the v2 module path, replacing the @latest install on
the old v1 path. The Dockerfile lint stage already pinned the v2.12.2
alpine image by digest and is unchanged.

Fix all issues surfaced by the strict config:

- err113: introduce wrapped static sentinel errors
- gocognit/funlen/nestif: split ExtractDay, Run, DumpAndCompress,
  VerifyOutput, and the CLI flag parsing into smaller helpers
- noctx: use ExecContext/QueryContext/BeginTx and CommandContext
- noinlineerr: replace inline if-err assignments with plain ones
- wsl_v5/nlreturn: add required blank lines
- lll: wrap long lines and SQL strings
- gosec: filepath.Clean on file open/create; bounded uint64
  conversion in CheckFreeSpace; named output dir permission constant
- mnd: use unix.FADV_* constants and named size constants
- revive: add package and exported symbol comments
- testpackage/paralleltest: move smoke test to bsdaily_test with
  t.Parallel()
- nonamedreturns: drop non-error named returns

The remaining nolint directives (gosec subprocess launches with
internal paths, unqueryvet full-row SELECT * copies whose schema is
defined by the source database) are each justified inline.
