Add 5 rule files for Swift following the established pattern used by
TypeScript, Python, and Go rule sets. Covers Swift 6 strict concurrency,
Swift Testing framework, protocol-oriented patterns, Keychain-based
secret management, and SwiftFormat/SwiftLint hooks.

The PreToolUse Write hook blocks creation of .md files to prevent
unnecessary documentation sprawl. However, it also blocks Claude Code's
built-in plan mode from writing plan files to .claude/plans/*.md,
causing "BLOCKED: Unnecessary documentation file creation" errors
every time a plan is created or updated.
Add .claude/plans/ path to the whitelist so plan files are not blocked.
Comprehensive coding standards for modern C++ (C++17/20/23) derived
from isocpp.github.io/CppCoreGuidelines. Covers philosophy, functions,
classes, resource management, expressions, error handling, immutability,
concurrency, templates, standard library, enumerations, naming, and
performance with DO/DON'T examples and a pre-commit checklist.
The inline environment variable syntax `TIMESTAMP="$timestamp" echo ...`
does not work correctly because:
1. The pipe creates a subshell that doesn't inherit the variable
2. The environment variable is set for echo, not for the piped python
Fixed by using `export` and separating the commands:
- export TIMESTAMP="$timestamp"
- echo "$INPUT_JSON" | python3 -c "..."
This ensures the TIMESTAMP variable is available to the python subprocess.

Round 125: Tests for readFile returning garbled strings (not null) on binary
files, output() handling undefined/NaN/Infinity as non-objects logged directly
(and JSON.stringify converting NaN/Infinity to null in objects), and loadAliases
with __proto__ key in JSON proving no prototype pollution occurs.
Total: 935 tests, all passing.
Round 124: Tests for findFiles matching dotfiles (unlike shell glob where *
excludes hidden files), getAllSessions strict date equality filter (wrong format
silently returns empty), and parseSessionMetadata title regex edge cases
(no space after #, ## heading, multiple H1, greedy \s+ crossing newlines).
Total: 932 tests, all passing.
Round 123: Tests for countInFile non-overlapping regex match behavior (aaa with
/aa/g returns 1 not 2), replaceInFile with $& and $$ substitution tokens in
replacement strings, and parseSessionMetadata CRLF section boundary bleed where
\n\n fails to match \r\n\r\n. Total: 929 tests, all passing.
Round 122: Tests for findFiles glob dot escaping (*.txt must not match filetxt),
listAliases limit=0/negative/NaN returning all due to JS falsy check, and
getSessionById matching old YYYY-MM-DD-session.tmp filenames via noIdMatch path.
Total: 926 tests, all passing.
- parseSessionFilename rejects Feb 29 in century non-leap years (1900, 2100) but accepts 2000/2400
- replaceInFile with /(?:)/g zero-width regex inserts at every position boundary
- parseSessionMetadata preserves raw markdown formatting (**bold**, `code`, _italic_) in titles
Total: 899 tests
Round 110: Tests for findFiles with unreadable root directory returning
empty array (vs Round 71 which tested subdirectory), parseSessionFilename
year 0000 exposing JS Date 0-99→1900-1999 mapping quirk, and uppercase
session ID rejection by [a-z0-9]{8,} regex. 890 tests total.
Round 109:
- appendFile creating new file in non-existent directory (ensureDir + appendFileSync)
- getExecCommand with ../ path traversal in binary (SAFE_NAME_REGEX allows ../)
- getAllSessions skips .tmp files that don't match session filename format
- grepFile with ^$ pattern verifies empty line matching including trailing newline phantom
- replaceInFile with self-reintroducing replacement confirms single-pass behavior
- setAlias with whitespace-only title exposes missing trim validation vs sessionPath
- countInFile with named capture groups verifies match(g) ignores group details
- grepFile with multiline (m) flag confirms flag is preserved unlike stripped g
- getAllSessions with array/object limit tests Number() coercion edge cases
- parseSessionMetadata: blank line within Completed section truncates items
due to regex lookahead (?=###|\n\n|$) stopping at \n\n boundary
- grepFile: sticky (y) flag not stripped like g flag, causing stateful
.test() behavior that misses matching lines
- getExecCommand: object args bypass SAFE_ARGS_REGEX (typeof !== 'string')
but coerce to "[object Object]" in command string
